Grand Slam is a television quiz show first created for Britain's Channel 4 in 2003. In its first and only series in the UK, the main host was Carol Vorderman. She was joined in the studio by analyst James Richardson. The off-camera "Questioner" was Nicholas Rowe.
The contestants taking part, all of them previous quiz show winners, were: Dee Voce, Geoff Owen, Olav Bjortomt, David Edwards, Mark Labbett, Clive Spate, Melanie Beaumont, Peter Lee, Gavin Fuller, David Stainer, Graham Nash, Michael Penrice, Michelle Hogan, Laura Richardson, Said Khan, and Duncan Bickley (who lost £218,000 on an episode of Who Wants to Be a Millionaire? in 2000). Each contestant paid £1000 to enter, which made up part of the prize fund (hence the title, which has a double meaning referring both to the sporting concept of a "grand slam" and to the entrance fee). The winner was Clive Spate.
