Celebrity SAS: Who Dares Wins' John Barrowman has revealed the real reason he quit the show after just 32 minutes during Sunday's opening episode. 

The former Doctor Who actor, 57, was seen vomiting before throwing in the towel and since claimed it was as a result of being 'made' to eat 'vile tofu' after being offered no other food. 

John, who is not a vegetarian or vegan, told The Sun: 'I would never eat tofu in my life, but you're so hungry, you just eat it'.  

The motion sickness sufferer was then forced to endure a two-hour car journey for the task, leaving him green around the gills. 

He said: 'Then it was projectile vomit everywhere and the tofu came up. I thought "I'm not going to make myself ill or hurt myself in order to try to prove something that I don't need to prove"'.

'And it was seriously me going "I am completely comfortable with who I am" I'm completely a happy person. We've all got our issues and problems, but I've made a mistake'. 

MailOnline have contacted Channel 4 for comment. 

John, who opened up about the flashing allegations he faced in 2021 that led to his axe from the DOI judging panel while on the show, began to vomit shortly after arriving at base camp for the first challenge. 

After the contestants put on their army uniforms the actor began heaving and declared 'I'm out'.

Asked by expert  Mark Billingham if he would like to see a doctor, John said: 'No, I'm done. I just, it's not for me, I know who I am and what I'm about, it's not for me'.

As the voice over said: 'After only 32 minutes on base, number 13 John is the first recruit to leave the course.'

Viewers had little sympathy for the actor and taking to X branding him 'pathetic' and a 'diva'.

Writing:  'Never seen anything more pathetic in my life. I bet you thought this might be a shot at redemption as well. Whoopsie!': 'Pathetic from John Barrowman': 'John Barrowman 32 minutes': 'FFS John Barrowman, I knew you were a diva, didn't think you were a huge wuss as well, certainly done yourself no favours there'.

'I hope John Barrowman wasn't paid for that pathetic effort': 'Can't believe John Barrowman quits the only show that was actually willing to give him a job after just 32 minutes. What a prat'.

During the episode, John addressed the accusations that he had repeatedly exposed himself on the set of the BBC One sci-fi series Doctor Who and its sister show Torchwood.

He said: 'The press made the allegation that I was going around putting my d**k on everybody's shoulders.

'Having that happen to me ruined me, but this course is going to help me push through this and I want people to see the kind of person that I really am.' 

He later added: 'On Doctor Who and Torchwood, I had to do a lot of nude scenes. If I were being stupid, I would do something stupid.'

Ahead of his SAS stint, John shared an awkward clip of himself preparing to start the course, telling followers that he had already 'thrown up' due to his nerves.

He said: 'So it is the night before we start the course. I've just barfed, and I'm gonna try to get some sleep now.

'No seriously, I threw up, I think it might have been something I ate, but I feel better. Let's see how I feel in the morning, so there you go - wish me luck!'

The clip then cut to John heading into the wilderness to begin the course, after handing his valuables and briefly calling his loved ones.

He added: 'I know it's dark outside and you probably can't see, but that's me doing the walk to my valuables, I've just spoken to Scott and sent my mom and dad, everybody a message to say, send positive vibes.

'I'm super scared but, it's good to be scared isn't it?'
