Richard Brittain was the overall champion of Series 55.
He accumulated 820 points in his octochamp run, but went into the finals as second seed to Steven Briers (840 points). Briers however then narrowly lost his quarter-final against eighth seed Phil Watson, a match which Brittain, watching from the audience, called 'an enthralling spectacle'. Brittain then comfortably won his quarter-final against Andrew Blades, but only narrowly beat Stu Horsey in the semi-finals before he trounced an off-form Tony Warren in the final, 103 – 60.
He returned for the Championship of Champions XIII and faced one of the favourites Jon Corby, and lost with the lowest score in the competition, including the disallowed words odontal ☓, biopot ☓, ommit ☓, saloneen ☓, and his now famous conundrum offering GANDISEEG ☓.
Brittain also appeared on the now-defunct gameshow Brainteaser in January 2007, less than a month after winning Countdown. He won the show and pocketed £1,500.
In November 2015, Brittain was arrested for assault after hitting an 18-year old ASDA shelf stacker with a wine bottle. He tracked her down to Fife and attacked her posting a negative review of his book online. He was sentenced to 30 months in prison, serving 14 of them before being released in January 2017.
Prior to being imprisoned, Brittain was an Apterite.
