Actor, comedian, musician and director Tim Minchin takes a break from creating hit musicals such as Matilda and Groundhog Day. He'll be competing along with leader of the Scottish Conservative party Ruth Davidson, Made in Chelsea star Jamie Laing, and singer Ella Eyre.

Prue Leith and Paul Hollywood pass judgment, while Noel Fielding and Sandi Toksvig guide the celebrity contestants, and also offer shoulders to cry on for the runners up. (thetvdb.com)
