Born in Watford, Hertfordshire, Walsh was initially a professional footballer before a Career-Ending Injury forced him to retire at 22, leading him to a career in comedy and acting. As a TV host, he initially broke through in the 1990s hosting the UK version of Wheel of Fortune, but is best-known for presenting the gameshow The Chase, which he's done since 2009. As an actor, he spent two years on Coronation Street as Danny Baldwin, starred in Law & Order: UK and, from 2018-2021, played Graham O'Brien, a companion of the Thirteenth Doctor in Doctor Who. As a singer, he has released two studio albums, Chasing Dreams (2016) and When You're Smiling (2017), that reached 10 and 11 in the UK Albums Chart respectively.
