Wheelchair racing star Jack Binstead will play a mouthy pupil in a new BBC comedy hitting screens next week.

The Chessington Community College pupil will star in a post-watershed sitcom about the “worst teachers ever to grace the British education system”. Teenager Jack said: “It is all about how these teachers are bigger kids than all the pupils. We all get up to a lot of mischief and there is a lot of comedy.

“I auditioned years ago when I was 13 – it has been a long process. More than 250 people auditioned for the role, but they held it for me until I was older. I was very lucky.”

Featuring rude jokes and witty one-liners, Bad Education follows the character of maverick teacher Alfie Wickers played by comedian Jack Whitehall, who is adored by pupils but hated by their parents.

The sitcom, which was written by Jack Whitehall, also features other big names including Gavin and Stacey star Mat Horne, who plays headteacher Fraser who constantly hopes to be as “cool” as Alfie. Athlete Jack, who filmed the series over a two-month stint while he studied for his GCSEs, said juggling all his commitments had been particularly hard.

He said: “When I was filming I was also studying and doing sport so it was incredibly difficult. I persevered but I was mentally and physically tired.

“I am still very much interested in sport, but I want to be a Paralympian and a great actor. “For now I am going to carry on doing both for as long as I can, but I know that at some point I will have to make a decision.”

His mother, Penny Binstead, said: “Jack loves acting but knows he needs to dedicate time if he wants a chance to represent Great Britain in 2016.”

Bad Education starts on Tuesday, August 14, at 10pm on BBC Three.
