Judith was the show's first ever winner, scooping the top prize almost 20 years ago in November 2000. Nowadays, she's one of the experts on BBC quiz show Eggheads.

The show celebrated its second top winner, David Edwards, less than a year later in April 2001. David had already triumphed on Mastermind and was a Mensa member so his win wasn't the most surprising ever, it must be said.

Anyone who watched the ITV drama Quiz will know the answer to this one, as winner Charles Ingram was later accused of cheating his way to the top, alongside his wife and a third accomplice.

Robert Brydges' win took place just 11 days after the infamous Charles Ingram "coughing" scandal (we can only imagine how closely he was being watched by producers at this point). The retired banker was even in the audience the night Ingram appeared on the show.

It was almost three years before Who Wants To Be A Millionaire? celebrated another win, which Pat Gibson managed in April 2004. In 2018, he was ranked the number one quizzer in the world.

Ingram Wilcox (another Ingram!) was the show's most recent winner in September 2006. His other TV appearances include Countdown, Brain Of Britain, Fifteen To One and Mastermind, but this was his first time winning.
