Richard Ayoade will once again be leading a celebrity team of contestants through the Crystal Maze, this time for a special Christmas edition in aid of Stand Up To Cancer.

The celebrity team taking on the Maze in this celebrity special are comedian Tom Davis, pro boxer Nicola Adams, reality star Ollie Locke, singer Mollie King and captained by swimming champ Ellie Simmonds.

The Aztec, Medieval, Industrial and Futuristic zones are festooned with festive frivolity and puzzling the plucky participants along the way will be The Knight (Jessica Hynes) and Jarhead (Adam Buxton).

The Crystal Maze: Celebrity Christmas Special for Stand Up To Cancer airs next month on Channel 4.
