A game show champion switched roles to become the quizmaster at a school.

Barry Simmons, from the BBC quiz show Eggheads, visited Mathilda Marks Kennedy School, in Hale Lane, Mill Hill, this morning, and held a quiz for pupils.

He also took part in a question and answer session about his life and his winnings on Mastermind, Brain of Britain last year, and what it was like to be an Egghead celebrity.
