Olympic gold medallists Dame Kelly Holmes and Sally Gunnell OBE know a thing or two about competition, and there's no stopping them when they head off in search of antique bargains.

Dame Kelly's running mate is her mum Pam, while Sally brings along her best mate Emma for support. The teams scour an antique centre in London and find a number of items which they hope will break all records at auction.

It's the turn of the funny guys as comedienne Helen Lederer, star of such hit series as Absolutely Fabulous and Naked Video, takes on comedian, impersonator and EastEnders actor Bobby Davro.

Helen, also known as a stage actress as well as being a wine critic and writer, is accompanied in her search for bargains by her big sister Jan, while Bobby shops with his partner Vicky, daughter of one of the Beverley Sisters and former England captain Billy Wright.

Society beauty Tamara Beckwith wants to prove she is as good a negotiator as acclaimed businesswoman Ruth Badger. The two women with two very different styles will each be trying to make the most profit when their items are sold at auction in London.

Tamara and her sister Clare, and Ruth along with her mother Edna, shop for bargains at an antiques fair in Ardingly, West Sussex. While Team Beckwith rely on well-honed shopping skills to select their items, Ruth and her mum use the power of negotiation to knock prices down to rock bottom. The teams are helped by antiques experts Anita Manning and Mark Stacey.

Theo Paphitis knows a good deal when he sees one, as he's demonstrated all too well on the hit series Dragon's Den. But will the top businessman know a bargain when he sees one?

Theo and his daughter Zoe use all their negotiating skills when they take on Jilly Goolden and her aunt, Jenny. Jilly is best known for her wine expertise but also has a track-record in antiques, having presented both the Great Antiques Hunt and Going, Going, Gone

Two talented performers find plenty to sing about when they go shopping for bargains at an antiques centre in London.

Connie Fisher, who rocketed to stardom when she won the role of Maria in the BBC's search for the leading lady to star in the West End Production of The Sound of Music, takes on Ian 'H' Watkins, former member of the phenomenally successful band, Steps.

This star-studded special features two funny men and their mums. The ever-so dry Julian Clary, with that razor-like wit and acerbic tongue, forms half of the red team along with his mum, Doreen. While the blue team features the sweet and lovely Matt Cottle, best known for stage work and leading performance in the popular sit-com, Game On, partnered by his mum, Christine.

Two television stars swap scrubs for Bargain Hunt fleeces. Rakie Ayola plays nurse Kyla Tyson in Holby City while Charles Dale plays popular porter Big Mac in sister programme Casualty. The two actors are old friends - but it doesn't stop them both wanting to be the best bargain hunter.

Rakie is joined on her quest for good buys by her father-in-law, actor Jack Smethurst, best known for playing the lead in the 1970s hit comedy Love Thy Neighbour. Charlie is helped by his wife Sara, a make-up artist.

Keith Chegwin and Sally James, once arch rivals on television, find themselves facing a different kind of competition when they hunt for bargains at an antique centre in Chiswick, London.

Sally takes time out from her shopping to chat to presenter Tim Wonnacott about her father, Bert Cann, a photographer who shot many of the most iconic images of movie and media stars in the 1960s and 70s. Tim also discovers Keith collects coins and borrows a few special examples any collector would love to own.

Best-selling novelist Jilly Cooper gives her typewriter a rest to take part in Bargain Hunt Famous Finds. She teams up with her son Felix to pit their bargain-hunting skills against EastEnders' mechanic Garry, played by Ricky Groves, and his dad Rob.
