Celebrity SAS: Who Dares Wins has been plunged into chaos, just days after filming began.
The Channel 4 show, which is being produced as part of the Stand Up For Cancer initiative, sees a number of celebrities taken on gruelling SAS training.
It has already proved too much for some though with three contestants already reportedly quitting the show, just days after arriving for filming.
TV presenter Ulrika Jonsson, 53, has reportedly found the going too tough and has walked away from the series after aggravating a back problem.
She was followed by former I’m A Celebrity Queen of the Jungle Vicky Pattison, 32, who also struggled with the tasks and threw in the towel.
This followed former X Factor star Jake Quickenden, 32, who was flown from the set in Scotland to London to see a specialist surgeon after suffering a serious injury.
