Sport Relief special. As you'd expect, there are a few changes to watch out for, including having Sport Relief celebrities walk up those famous stairs to accompany the cash-hungry entrepreneurs in their bid for investment.

To kick off the episode, funnyman Patrick Kielty lends his support to an improbable-sounding invention - the Sideways bike. Two sisters from Southampton hope the Dragons will see the potential in their bottom-toning prototype, ably demonstrated by Ruby Wax. Olympic champion James Cracknell lends a hand to young businessman Liam O'Reilly and his dancing troupe; and Greg Rusedski leaves his tennis racket behind to help two Irish entrepreneurs pitch their portable sports stadium aimed at kids. Jason Manford and Iwan Thomas both have to stand in front of the Dragons and respectively pitch a spectacle-stabilising attachment for sports caps, and a sat nav for skiers.

Before entering the Den, the Dragons and entrepreneurs have all agreed that some of the profits from any investment will go towards Sport Relief. But when it comes down to business, the same rules apply; it's the Dragons' own money and only the very best ideas will succeed. In this tough arena, facing some of the best minds in the business, will any of these hopeful entrepreneurs convince the fearsome financiers that they should walk away with their cash?

Plus, the Dragons visit the Kibera slum in Kenya to find out how the money raised by Sport Relief is helping those in need.

Budding entrepreneurs approach 5 of the best business minds in the UK with the hope of securing financial backing for their business proposal. Can they in a few short minutes persuade the Dragons that they are a sound investment? Or will they get shown the door?

Budding entrepreneurs pitch their business ideas to five investors – Peter Jones, Duncan Bannatyne, Rachel Elnaugh, Doug Richard and Theo Paphitis – collectively worth over half a billion pounds. If the investors like an idea, they're ready to invest their own cash to kick-start the business. But if they don't like it, expect drama as the dragons show no mercy and tell the budding entrepreneur in no uncertain terms to stop wasting their time.

The investors are confronted by an innovation in pub snacks, branded underwear, a solution to rolling beer bottles in the fridge, a wi-fi business aimed at yachties and many more. Will anyone leave the den with the cash they need to launch their business dreams?

The Dragons finally meet their match as clean shaven Jay Cousins brings his Orikaso folding plates to the foldaway table.

Series revealing the lives of the Dragons' Den dragons. How did they make their millions? And what are they really like?

In the first of the five programmes focusing on the dragons, we are on an access-all-areas journey into the life of Theo Paphitis. We hear what Mrs P and the children, whose inheritance he keeps spending, think of him; we also get a quick peek into the luxurious lifestyle of a multi-millionaire businessman. While Theo rebuffs the notion that he is the classic rags to riches story, we gain a valuable insight into how his upbringing influenced his business career, get some tips on what it takes to be a future dragon and find out what his rival dragon investors really think of him.

We also discover how some of his most memorable Den investments are getting on, including iTeddy and Ben the Bin, as well as hear from one entrepreneur who accepted an offer from Theo inside the Den, but in the end chose to walk away from the deal.

In this episode, we gain unprecedented access into the life of James Caan. We discover why his daughters cringe at some of his appearances in the Den and get a glimpse into the jet-setting lifestyle of a multimillionaire businessman as he breakfasts with his wife in Cannes, checks up on some business investments in Lahore and gets an update on his latest venture aboard his own luxury superyacht, specially designed to meet James's meticulous demands.

As a private equity investor, James is a dragon both inside and outside the den and so as well as getting an insight into how he spends his millions, we also discover some of the secrets about how he made them, why he chose not to go into the family leather business and why he changed his name.

Finally we discover what his rival dragon investors really think of him and how difficult it has been being the new boy; also, we catch up with some of his most memorable investments. Will his doggie treadmill earn him another fortune? How has Laban Roomes and his gold-plating business coped with James' attention to detail? And just four months on since shaking hands on the deal, has life changed for glamorous events company, D4M?

Series revealing the lives of the Dragons' Den dragons. How did they make their millions? And what are they really like?

Deborah Meaden is next up in this five-part series profiling each of the current dragons. Having made her fortune in the leisure industry, Deborah's back at Butlins, the home of her first venture into entrepreneurialism: a bingo concession. We find out from her husband Paul what he thinks of being married to a dragon; discover what it's like being the only female dragon in an otherwise testosterone-fuelled den; and hear from a former employee about how tough she was to work for. The answer? Very.

We also catch up with some of Deborah's Den investments and discover how the businesses are developing with a dragon on board. One of Deborah's most memorable investments, Sarah Lu and her You Doo Doll, has developed into a full range of products including a You Doo Dog. Deborah's killer heels don't get in the way as she climbs aboard an HGV truck with another den investment, JPM Logistics, as they ferry topiary elephants around London; and we're with recycling company ProWaste in the first few weeks and months of dealing with a dragon outside the Den.

It's Peter Jones' story next in the penultimate programme in this series. He made his money in the telecoms industry, but has gone on to become one of the most high-profile businessmen in the UK. With unprecedented access to Peter's business and personal life, we follow him as he visits 10 Downing Street for a meeting with the prime minister; at home with his five children; and discover how he made, and why he lost, his first fortune.

We also catch up with some of Peter's investments, which are among the most memorable in the Den. Both Levi Roots and his Reggae Reggae Sauce have become household names, but how much money are they making? And Hamfatter, the first band to enter the Den, ended up being able to choose between offers from four dragons. Peter won that battle, and we catch up with them all during the band's recent UK tour and discover whether their dragon backer has managed to turn them into a profitable proposition.

In the final programme of the series, it is Duncan Bannatyne's turn to open the door into his multi-millionaire world. Having grown up in the shadow of the shipyards of Clydebank, he makes an emotional visit to the local pub where he used to play dominoes with his father and talks about some of the events that shaped his life. We see a very different side to the tough-talking, plain-speaking dragon as he explains how his unconventional CV is ideal for anyone who wants to be a successful entrepreneur.

We are with Bannatyne's family as they holiday in their luxurious villa in the Cote D'Azure, track his business career to find out where he made his millions, but also discover that his straight talking manner is unsuprisingly not confined to the den.

We also trace some of his most memorable den investments and find out what happened once the deal was done - from the all-singing, all-dancing Razzmatazz franchises, through to the successful logistics company Igloo and the electrical wiring connector that is selling in the millions and has turned its inventor Peter Moule into a mini-dragon in his own right.

An entertaining and illuminating journey through the 18 other countries that now have their own versions of the hit programme. Featuring some of the most bizarre inventions and cringeworthy pitches, the angriest exchanges, as well as the joyous moments when the plucky entrepreneur actually gets investment.

On the second stage of its tour of the UK, Dragons' Den: On Tour heads back on the road proving that, even in tough times, entrepreneurialism is fighting fit in our cities, towns and villages.

The tour heads into London for episode two where a visit to one of the most successful entrepreneurs not to get investment - Shaun Pulfrey and his Tangle Teezer brush. But will Duncan Bannatyne agree with Shaun that the Dragons got it wrong?

Theo Paphitis opens up his contact book to put the team of his recent investment 'Ice Blading' through their paces, and Peter makes a play for Theo's title as the 'Den Destroyer' by getting physical with the products of Jason Robert's Tech21.

Deborah Meaden investigates a change of business direction for one of her early investments 'Mix Album', and the team from Blindsinabox get some serious motivational management from a fired up James Caan.

This episode features Alan Mandel Butler and his company Apocalypse. The Den is the stuff of nightmares for most, but what reaction did they get once they asked the Dragons for a two hundred thousand pound investment in their horror-based scare attraction? The investors may be used to being the leading characters in the Den, but how will they respond to London-based Australian Katie Olver who has them starring in her personalised romance novels? Also featured in this episode are Aberdeenshire's Eddie Middleton and his eco-friendly patio heaters, a more cat-friendly collar, and a revolutionary new hat that makes your wrinkles disappear. All that and an invention that puts an end to nuisance phone calls.

What will the Dragons make of poker player JJ Hazan's proposition? Oscar-nominated make-up artist Beverley Binda wants to launch a new range of cosmetics for darker skin, and corporate team builders BassToneSlap from Nottingham hope to drum up support for their business by offering up probably the noisiest pitch ever heard in the Den.

Also fronting the Dragons are Scunthorpe's Sharon Wright, who has worked day and night on her own to launch her first invention in the UK but needs the Dragons' expertise to take it global, and trained barrister Adejare Doherty who pleads his case for his new range of eco-friendly disposable dinnerware. Will the Dragons give him the 120,000 pound verdict he needs?

Launching a new musical is a notoriously risky venture; will Kent-based theatre director and former Pebble Mill presenter Josephine Buchan hit the right note in her quest for cash? East London brothers Oliver and Toby Richmond hope there will be no stalling when they ask the Dragons to invest in their car servicing company. A former GCSE project takes centre stage when Welsh student Emily Webb asks for 75,000 pounds to take her invention to market, and Rugby duo Frank Drewett and Lawrence Webb hope a Dragon's backing will help lift the lid on the potential of their wheelie bin accessory.

Can Tony Earnshaw and Steven Pearson make a clean sweep with their regional cleaning company? Karen O'Neill and Karen Coombes could be skating on thin ice by coming into the Den with their new invention to help budding Torvills and Deans all over the country; and will advertising consultant and budding entrepreneur William Sachiti get the money he needs to roll out his new litter bin that he describes as 'approachable'?

Father-and-son team Phillip and Robert Pain hope that the well-travelled multimillionaires will fund their extraordinary multipurpose suitcase-come-sunlounger to the tune of 200,000 pounds, and Patrick Thirkell from Moray in Scotland hopes to catch a Dragon with his new offshore seafood company.

For Lancashire-based Paul Ward, the current swine flu pandemic has boosted sales of his bug-busting cleaning products, but will the Dragons be impressed enough to invest? Carol Savage from Hertfordshire hopes to cook up a frenzy with her online community for food lovers, and whilst the Dragons are no strangers to fine wine, can serial entrepreneur James Nash entice them to pour investment into his innovative single serve wine containers? Meanwhile, can jewellery and fashion designer Jane Rafter walk away with investment for her range of customisable sandals? Finally, the Dragons come face-to-face with themselves as a Midlands trio ask for 50,000 pounds for their customisable masks.

The economy may have contracted but the same can't be said for the Dragons' business portfolios as they pledge more money than ever before to cash-strapped entrepreneurs. But it's still their own hard-earned fortunes they are risking and anyone expecting an easy time is in for a rude awakening at the top of those famous stairs this week.

It's not easy when Deborah Meaden declares you've given possibly the worst pitch in the Den, but that's just what Manchester inventor Samantha Gore heard last series as her pitch fell apart. That hasn't deterred her though, and she's back again with another addition to her crime prevention business and continued dreams of investment. Fellow Mancunian and classical pianist David Schofield is hoping his youthful take on the classics will get a Dragon to finance his future recordings. Also aiming to succeed is Ronan McCarthy from Surrey with his 21st-century take on the shoe polish booth. Personal biographer Michael Oke hopes he can start a new chapter in his life and get one of the five dragons to back his publishing venture, whilst West Midlands duo Peter Neath and Ian Worton hope they'll stand up to the investors' grilling and secure some much needed cash in their sausage cooking accessory. Devon mother of two Nikki Povey brings along a couple of interesting friends in a bid to appeal to the Dragons' fun side, and London businessman Jason Roberts pitches his range of protective coverings for mobile phones and computer equipment.

Another diverse mix of businesses and entrepreneurs go before the multimillionaire investors.

Hampshire-based businessman Stephen Voller hopes the Dragons won't put the brakes on his new electric car invention, as he smashes the Den record for the most money ever asked for. But will he walk away with the cash?

Serial inventor Michael Pritchard hopes to clean up in the Den with his revolutionary invention that allows every last drop of liquid to be used in household product sprays. Young Bolton entrepreneurs Umar Mohammed and Ahmed Suleman hope they'll get investment from a Dragon with their fast food curry trays.

Also heading up the stairs are London sisters Audrey and Sophie Boss, who want to gain lots of extra pounds from their new approach to weight loss. And there's a touch of fantasy in the Den as Norfolk-based craftsman Russell Bowlby pitches his range of high-end children's play equipment.

A husband and wife team from Warwickshire, David and Patti Bailey, believe they have every executive's dream, with a range of computer mice based on iconic classic cars. Ever wondered how to get the last bit of toothpaste from the tube? Susan Bell and Jonathan Jones have an invention that can do just that, and are looking for 75,000 pounds to take it to market.

Michael Lea from Cheshire reckons that good food is always in demand, even in a recession, and wants a Dragon to back his novel hot and cold food van. Also, young Manchester student Vernon Kerswell hopes the sky's the limit with his extreme remote-controlled microhelicopters.

Featuring the team behind Ladderbox, sculptor Guy Portelli and olive oil man Michael North.

This episode is already in Specials and should be deleted from Season 7.

The Dragons are off to the Midlands, Oxfordshire, North Lincolnshire, Cambridgeshire and Essex to discover whether business is booming, or if the recession has dampened the spirit of entrepreneurialism in our cities, towns and villages.

The Dragons catch up with the band Hamfatter to find out how the Den's first rock investment is doing. Duncan pops in to sign the deal with one of the stars of the 2009 series, Sharon Wright, who came to the Den with an invention for putting cables through walls.

Deborah checks up on a very flamboyant interior furnishings company, while James pays a visit to one of his investments whose business plan had to be totally revamped because of the economic climate.

Finally, Theo meets up again with one of the Den's most successful entrepreneurs to find out why her Road Refresher dog bowl was apparently good enough for the President of the United States, but not for the Dragons!

Having travelled across the North, South and East of the country, the destination for the fifth and final stage of the Dragons' Den tour is the West.

James Caan visits Clive Billing, the man who caused astonishment in the Den by spurning an offer from three Dragons. Deborah Meaden enjoys the opportunity to see Buggyboot hit the shelves, while Theo Paphitis welcomes a very special new addition to the Magic Whiteboard family.

The realities of business hit home as Peter Jones visits aspiring motorsport enterprise British Racing, and Duncan Bannatyne catches up with Rapstrap, one of his investments.

The Dragons are back and hungry to secure themselves the best deal. These are challenging times economically, but that hasn't deterred the nation's entrepreneurs from pitting their wits against the multimillionaire investors. In this series, a record number of entrepreneurs walk up the famous stairs to ask for an all-important cash injection that could transform their businesses and change their lives.

The rival multimillionaires may be used to the odd glass of something sparkling, but Devon-based vineyard owner Geoff Bowen hopes his unusual business proposition will tempt them into investing. Inventor Derek Cozens thinks that road signs are so last century and wants to drag them into 2010 with his new product range. Do Dragons have a sweet tooth? One 24-year-old mum from Preston, Kirsty Henshaw, hopes they do and that it's the best way to get the cash she needs for her frozen pudding business.

It wouldn't be Dragons' Den without a product getting tested to destruction, and calling a product 'safe' is like a red rag to a bull for one particular Dragon.

t's a vintage Den this time as London-based Angela Newman invites the multimillionaires to invest in her business which celebrates the glamour of a bygone era. The Dragons like their fair share of glamour, but do they like it enough to invest?

Another hopeful is John Jackson, a 72-year-old inventor from Essex who thinks the humble washing line needs a modern day revamp and is hoping the Dragons agree.

And have engineers Robert Leeds and Guy Seymour come up with the perfect investment for the multimillionaire who has everything? It's an ideal fit for their luxury yachts, the biggest product ever seen in the Den and one of the largest investments ever requested. But will the entrepreneurial duo sink or swim?

A Manchester-based entrepreneur thinks he has invented the cut-price alternative to a romantic weekend away - a rental kit that transforms an ordinary bed into a four-poster.

The bottled water industry is worth millions and Guy Jeremiah from London wants to tempt the Dragons with his green alternative - a collapsible, reusable bottle. The multimillionaires are usually all for inventions that save money, but is this a step too far?

Sam Petter brightens up the Den with her mission to get kids more active; and Lancaster duo Peter Harrison and Wesley Downham are hoping that their security company is a safe bet for the Dragons. Between them, they have plenty of experience in facing down tough characters, but will that help them hold their own with the Dragons?

The Dragons have shown willingness to invest in the best business deals offered them, but they won't risk their cash on those without money-making potential. More entrepreneurs ascend the stairs to see what the multimillionaires will make of their idea.

There is an unusual visitor in this episode, as Monty the falcon accompanies Layla Bennett from Powys into the Den. The bird plays an important part in Layla's pest control business - but will he help her hunt down an investment? Lisa Marshall and Shelene Mitchell have an invention which takes the old-fashioned hanging basket to new heights. Now they need the Dragons to help their business grow. And can graffiti be turned into a money-spinning business? Tim Williams and Tom Hogan think they have the technical wizardry to make it happen - but the writing will be on the wall for the innovative pair if they can't convince the Dragons.

Paul Morris from Harrogate believes he's cracked the genetic code of an acorn to make genetically engineered pig feed. Is it a ground-breaking discovery or will the Dragons think it's all hogwash? Mike and Sarah Longthorn, and Laura Booth from Hull think they have the perfect welly for festival fashionistas braving the mud. Inventor Ehsan Yazdani from London shows off his portable mini gym for fitness fanatics on the go, but can he convince the Dragons that his business is in good shape?

And if that wasn't enough, Reverend John Berriman from Cornwall has invented a new flavour of fizzy drink with a very unusual ingredient. It's time for a Dragon taste test - will the Reverend pass or fail?

Another set of hopeful entrepreneurs pitch to the multi-millionaire investors.

Northern Irish mum Jacqueline McKay thinks she has the stress-busting accessory for travelling parents everywhere - a suitcase that turns into a cot. Businessman Stephen Maher has a shattering pitch that he hopes will grab the Dragons' attention and an investment in his emergency escape invention.

Plus, Ralf Klinnert thinks his musical cones have money making potential, and the world's smallest car is in the Den. The Dragons might be tempted to a race - but will it be a race to invest? And, more importantly, will Peter Jones fit into it?

Technical wizards Chris Barnardo and Richard Blakesley from Hertfordshire have opted for the traditional method of Dragon-slaying-magic. Will their remote control in the shape of a magic wand have the power to turn a good idea into gold?

Intrepid business partners Letitia Valentine and Alex Lewis invented a new version of the foil survival blanket after a cycling trip to the Brecon Beacons. They've handled tough conditions before - now they have to survive the den.

Edinburgh duo Sandy Maxwell-Forbes and Sarah McClean have a helping paw from their dogs, Molly and Womble, as they seek investment in their outdoor dog creche. And Alastair Heelas hopes to impress the multi-millionaires with his inflatable snow globe. Will it attract a flurry of offers or will he face a frosty reception?

Young entrepreneur John Buni from London brings futuristic laser beams into the Den. His modern take on tailoring uses a laser body scanner to collect measurements for bespoke suits. The Dragons know all about fine tailoring, but will this idea measure up?

A father and son duo have invented a plastic vest to help gym-goers lose weight as they work up a sweat. Now they want the Dragons to see the potential in their idea and help them gain the extra pounds they need in investment.

Plus, a website venture supplying vehicle accessories is ready for the extra push a Dragon investor can bring, and serial inventor Solvej Biddle brings her latest innovative idea into the Den. It's a backpack that converts into a travel play-kit for children - a tough market to crack, but she thinks she has what it takes to convince a Dragon to help fast-track it to success.

Hoping to follow in the footsteps of the likes of Kirsty Henshaw, Angela Newman, Chris Barnado and Richard Blakesley, Ian Taylor rides into the Den with his mobile video advertising hoarding on a bike. He wants to expand his Wakefield-based business into the rest of the country, but will the Dragons see nationwide potential in his idea?

One of the Den's youngest entrepreneurs, 20-year-old Jessica Ratcliffe, thinks she's found a way into the lucrative computer gaming market with her online marketplace for selling and swapping used games. Now she wants to persuade a Dragon that they need a piece of the action. Plus another young but very experienced entrepreneur has an accessory that solves a problem all parents of newborns will relate to - how and where to change your baby's nappy in a public environment. But will the multimillionaires recognise the issue and. more importantly, will they spot a money-making opportunity?

Also, there's a round-up of the highlights from the series.

The series following each Dragon as they return to their day jobs starts with Peter Jones.

It may be a time of austerity in the UK but not so in the Dragons' Den... business is booming as the self-made multimillionaires return to the screen, ready to boost the economy by investing in the brightest and best of Britain's entrepreneurs.

Whilst the rules of the series remain the same, you will notice one change... the arrival of new Dragon Hilary Devey, who joins the line-up of the five fearsome financiers. Having scrimped, saved and self-sacrificed in the haulage industry to make her own fortune, Hilary has her own views on the products and businesses brought before her, and she's more than happy to take on her rivals in order to get the best deal.

34-year-old Georgette Hewitt, from Kent, finds out exactly how nerve-wracking it can be to climb those famous stairs and pitch to the Dragons. It's a real battle to compose her nerves, but one she must win in order to tempt the multimillionaires to invest in her answer to a common birthday party headache familiar to all parents. Entrepreneurs often take advantage of the latest government schemes and incentives when building their business, which is exactly what Chris Hopkins from Yorkshire has done by capitalising on the solar power feed-in tariff. But when a Dragon knows your industry inside out it's not always what you want. Add into the mix the most unusual use you could ever think of for a plastic egg, a circus act that's sure to go with a bang, and a mind coaching massage service, and you've got a formidable showcase of the Great British spirit of invention and innovation.

As ever Evan Davis is on hand to dissect the events, with further action and reaction available through the Red Button.

Dragons' Den continues with eight more intrepid entrepreneurs pitching Britain's brightest ideas to the multimillionaire investors. Will any of them manage to make the Dragons part with their cash?

Tonight's episode sees Londoners Krissy Sims and Kerry O'Brien AKA DJ Trickles and Lady MC enter the Den with a state-of-the-art turntable extravaganza in the back of their 4x4. The Dragons are often happy to demo a product but it is the business and how it makes money that remains their ultimate concern. Husband and wife team Liz and Alan Colleran from Dewsbury may be pitching their comfy caravan product - but will their Den experience be quite so luxurious and comfortable?

Elsewhere, an Englishman, a Norwegian and a Scot walk into the Den. Shades for canines are on offer, there's an inflatable car-based device like you have never seen before and a Kent-based entrepreneur thinks honesty is the best policy when pitching without a formal business plan - but with an offer to help everyone get the perfect looking body for just 20 pounds.

With further interviews and reaction available via the Red Button at the end of the programme.

It's a Den full of family businesses. Tim and Meena Kalia and their business partner Tricia Tierney try to talk the Dragons into investing in their innovative litter trays for dogs. The Den is taken over by a pirate, a street urchin and a hippy as Peter and Michelle Hart, plus five of their seven children, pitch their fancy dress business; but is their dream of investment pure fantasy? Brothers Jim and Richard George from Malvern believe they're in a strong position with their fence preservation company which is already trading. The business-savvy siblings have a deal in mind - but will the offer they're holding out for materialize?

Others looking for Dragon investment include an 'all you can drink' membership club, an exercise suit that claims to burn extra calories, and some giant knitting needles.

Some of the nations' budding businessmen and women have already entered the Den, but so far not all of their products and inventions have received a rave reception. This episode sees more intrepid entrepreneurs climb the stairs in the hope of realising their own investment dreams. Numbers are crunched and ideas are interrogated as the five fearsome Dragons weigh up which side of the coin their decision to invest will come down on.

A former disc jockey has a strategy, dress to impress to catch the attention of an investor. The DJ may have worn a DJ, but is that all it takes to part a Dragon from their cash? A Londoner hopes to alleviate a common worry for holidaymakers by locking up their valuables, but with just 5 per cent of his company on offer, can he guarantee a valuable return? Monterrey-born Marcela Flores Newburn pitches her Mexican food range complete with a full mariachi band, another budding entrepreneur asks the multi-millionaires to think of their homes, not as houses but as a source of income, and a former hairdresser has a product that makes money from thin air, but does he have the business plan to match?

Dragons' Den is once more open for business, with the five multimillionaire investors ready and willing to invest in Britain's best commercial prospects.

This time all the world's a stage and the Dragons merely players when two business partners from Lincolnshire pitch their pantomime company. But by turning the Den into a makeshift theatre, can they prove that show business and financial business really do mix?

Elsewhere, one entrepreneur uses his pitch to tell the Dragons a story about growing up in South Africa, rather than concentrating on facts and figures, but how will that go down with the multimillionaires?

Plus two joggers enter the Den to pitch their fast-paced delivery service; and a young mum offers a solution to everyone's outdoor toilet needs.

Profitability and bottom line are back on the agenda as more business proposals are pitched to five of the most successful commercial brains in Britain. Each of the entrepreneurs entering the Den are hoping to convince the multimillionaires that their business is worthy of financial backing, but as well as a good product it takes steel and determination to secure the Dragons' cash.

There are mixed fortunes in the Den this time as fashion-conscious twins try to persuade the Dragons to buy into their clothing range, a Teesside-based entrepreneur has a run-in with the investors over his decision to separate out the assets in his company, and a former firefighter asks the Dragons to invest in a car that thinks it's a bike.

One multimillionaire also gets their feet wet while trying out a beauty treatment administered by fish, but will a bit of Dragon pampering lead to a clean sweep of offers?

This week, a former milkman pitches his balance bike business accompanied by his three-year-old daughter, will a little person in the Den help persuade the Dragons to invest? Three London-based friends present their hands-free pint-pulling product, and a grandmother from the Isle of Wight, demonstrates a modern take on the ancient Greek practice of swinging... There's also a potential solution to help aid a common problem experienced by babies...nasal mucus extraction.

Two entrepreneurs have a plan to revolutionise the UK housing market, while another pair hope their unusual garden pods will persuade the Dragons to part with their cash. Elsewhere, a husband and wife team believe they have created a must-have accessory for women, and two of the youngest-ever participants enter the Den to pitch their record label. Presented by Evan Davis.

A former professional boxer spars with the Dragons, charming them with his no-nonsense pitching style, and isn't afraid to get down and give them twenty. A twenty-seven-year-old from County Down faces some tough questions over his valuation at ten times the revenue he is forecasting, not a thing that traditionally endears an entrepreneur to an investor.

And it's all too much for one emotional entrepreneur who struggles to hold back the tears when pitching her new hairstyling concept.

Plus, a Warrington-based chip shop owner showers the Den in confetti, three friends from North London perfect the art of miming in their pitch, and the multimillionaire investors find themselves singing about vegetables.

A Welsh grandmother has the Dragons in fits of laughter as she cooks up a storm and offers a percentage in her food loving website. Usual Den rules are blown out the window when a Tyneside couple pitch their innovative haircare brand for children, and the man who has built the world's biggest sand sofa tries his luck for investment.

Elsewhere, Peter Jones tries out an interactive game in a urinal, Deborah Meaden tries lava bread for the first time and Hilary Devey reveals what a multimillionaire's horse eats for breakfast.

Eight more intrepid entrepreneurs brave the Den hoping to gain a major cash boost for their business idea. It's a tense place to pitch with so much at stake, and these Dragons are famously hard to impress. The hopefuls will need to hold their nerve if they wish to succeed in getting the investment they require to take their business to the next level.

A horror story writer attempts to scare the Dragons into investing, but doesn't quite get the reaction he expects, in fact it's a reaction never before seen in the Den. There's a blast from the past as two Mancunian sisters who first walked up those infamous stairs back in 2005, are now asking for investment in their new gluten free oriental dipping sauce range, but will it be a case of better luck second time around? And with the kids all back at school, two friends hope now is the right time for investment in their innovative children's backpack designs - have they got what it takes to part five of Britain's most successful business men and women from their hard-earned cash?

Also pitching to the multimillionaire investors is a Northern Irish inventor with his unique range of wearable luggage, and love is in the air when two Dragons tie the knot using a rather unusual vending machine.

The Dragons' competitive natures are put to the test when the Den is turned into a game show set, as a former chat show host seeks investment for her television quiz idea. Although she has experience in this area, will the Dragons think the price is right? A 22-year-old student from Bolton surprises the Dragons with his unbridled enthusiasm for the UK's car parking industry, and a father and son from Yorkshire cause consternation among the multimillionaire investors with their firm, no-nonsense negotiating style. Also pitching for investment in the Den are a samba band, flowering tea and a man washing his hair with the help of a fully working shower.

Two graduates aim to impress the Dragons with their update to a 200-year-old invention, a product they believe creates a whole new way of advertising on Britain's streets. Will the pair's futuristic demonstration be enough to secure the cash they desperately need, or will the investors spot a fatal flaw? A beauty lover from Birmingham pitches possibly the smallest product ever seen in the Den, and a Lancastrian father of three has some explaining to do when his business building wooden huts comes under close scrutiny from the five multimillionaires. Other ideas seeking investment in Den include a multi-directional paint brush, a solution to the troublesome problem of 'pillow slippage' and a taxi driver's security invention, which is put through the Theo Paphitis break test.

It is another busy week in the Den as eight more entrepreneurs pitch to the Dragons for a cash injection in their money-making ideas. Often, a visual aid helps get across what is being pitched, and this time there is a plethora of props to help the multimillionaires understand the commercial potential of the businesses on offer. A ballroom dancer turned inventor brings a bit of sparkle into the Den via a tango and a glitter ball; Theo Paphitis and Peter Jones crawl into a new concept for the camping industry; and a labrador called Margot helps to sell the idea of doggy ice cream. Also in the Den: a world kickboxing champion, two Welshmen with their celebrity-backed toffee vodka, and three friends from London who hope to capitalise on empty loft space.

Dragons' Den is where life-changing business deals are made. The five multimillionaire investors are looking for the next big money-making ventures, so any attempt by an entrepreneur to deflect a question or change the subject can lead to some choice words and a quick exit. This week in particular the Dragons seem to have got out of their million pound beds on the wrong side. Tempers flare when one entrepreneur offers just one per cent of his business, valuing it at 15 million pounds; hackles are raised by a toastmaster from Staffordshire looking for investment in his 'male intimate wipes'; and the Dragons live up to their name when deciding whether to invest in an online store for second-hand goods. But can any turn it round and secure the investment they need? Also facing the Dragons are a TV stuntman pitching his horror-themed paintball experience, a husband and wife with a new DIY product and a man from Birmingham who believes his darts invention is a world first.

The Den is down a Dragon as Hilary Devey is temporarily absent, however while only four multimillionaire investors preside over proceedings, they are as keen as ever to find the next big thing to back with their hard-earned cash. In this episode recorded before his own heart scare, Duncan Bannatyne and his rival Dragons get to see how a doctor, a nurse and a paramedic would treat a cardiac arrest in the Den. Plus a nervous Aldershot butcher seeks investment in his award-winning sausages, and a father and daughter team from Hertfordshire showcase their troop of drummers. Also in the Den, a first time inventor advises how to keep dry while cleaning your car wheels, a former teacher asks the Dragons to make origami puppets, and an inanimate object speaks for itself and asks for £50,000.

Business pays no mind to age. A bright idea can strike at any time of your life, and just as long as it's profit-making, it should pique the interest of the multimillionaire investors. The entrepreneurs pitching to the Dragons tonight have over 60 years difference in age between them, but will any of them succeed in securing investment? On tonight's programme, a Birmingham-based nurse with a love for hats demonstrates her toilet product; a product designer, who's travelled all the way from Singapore, pitches his new tablet computer; and a husband-and-wife team from Bradford try to convince the Dragons that their caravan covers are really something to get excited about. Also in the episode: a Halifax mother of two with her oven cleaner, an invention from an airline pilot that can tow children, and a four-year-old boy pitches for a seventy-five-thousand-pound investment and a bag of sweets.

With the Den nearing the end of the series, time is of the essence for the next set of entrepreneurs pitching to the Dragons for a life-changing investment. Who will succeed where so many others have failed? Security is needed as one Cambridge-based entrepreneur is overwhelmed by paparazzi when pitching his new business idea, a keen golfer presents his very special glove, and a Nottingham-based couple want to take a slice of the UK's seven billion pound DIY market with their update on the simple paint brush. Also this week; a driving school for 14-year-olds, an electronic bed stored in your ceiling, and two friends hoping to make money out of thin air.

Tonight sees the penultimate episode of the current series, with more intrepid businessmen and women hoping to receive a cash injection from the five multimillionaires. The Dragons have already proven that they are willing to invest in the right idea - will they spot the next big thing tonight? Entrepreneurs include: two Berkshire design graduates who think they've solved the multiple-pint juggle when carrying a round back from the bar, a former celebrity PA who has an awkward moment when her mobile phone rings during her pitch, and an ex-DJ from south Wales who hopes his role-play disco will best demonstrate his product for sore feet. Also pitched are a website for 'amazing' retirees, a gadget to reduce our food waste, and a car that's also a barbeque.

The Den doors are closing after another record-breaking series, and despite the recession the five multimillionaire investors have dug deep to pledge 1.75 million pounds to some of the UK's brightest businesses. In the final episode of the series, two friends hope the Dragons are in the party spirit as they tempt them with their frozen cocktails, a keen sailor demonstrates a nautical use for part of his car, and Peter Jones meets his namesake pitching a safety product for babies. Plus, a device to stop your tights falling down, an inflatable Christmas tree, and a beekeeper complete with a swarm of bees.

Christmas is big business. Across the UK, thousands of entrepreneurs are dreaming up new products and innovative ideas to try and cash in on the annual big spend - over £36bn in 2011. And if there is money to be made, the Dragons are never far away. Now, for the first time, the Den opens its doors purely for commerce at Christmas. Budding businessmen and -women pitch their festive companies in the hope of securing a much-needed cash injection from the five multimillionaires. An entrepreneur from Surrey, also known as Mrs Christmas, turns the Den into a grotto, while two friends from south London encourage the Dragons to try some traditional game play. Plus, a former dinner lady from Huddersfield offers her take on Christmas cake, complete with brussels sprouts. But it would not be the Den if there were not a few business curveballs, so also descending the stairs are a Secret Santa, who demonstrates his hope for the Christmas No 1, two Liverpudlians who host a Dragon party, and a mother and son who offer up festive knitwear for all the family... not forgetting a range for pet dogs, and a 'bah humbug' option for any grumpy knitwear fans out there. This seasonal treat also includes a chance to catch up with some of the entrepreneurs featured in the Den. Will they be this year's festive hit? Or will this most competitive time of trading swallow them up and have them for Christmas dinner?

In this catch-up special, Angela Scanlon discovers what happened next for some of the most memorable entrepreneurs to have survived the Den.

Peter Jones, Deborah Meaden, Touker Suleyman, Tej Lalvani and new Dragon Sara Davies take us beyond the Den and into the brave new business world of their most promising investments. What is it like to strike a Dragon deal worth millions of pounds? How has the Den lead to a murder trial for one businessman? And Angela settles on the sofa to relive tough, tense and funny moments from recent series with the entrepreneurs who will never forget them.
