MP Nadine Dorries has told Daybreak that Andrew Mitchell never gave her permission to appear on I'm A Celebrity. "But he did give me permission to have the month off," she said.
She added "I find it quite disappointing now, that now the spotlight came onto this, that he has chosen, and particularly after all the support I gave him during his own particular troubles recently, that he's tried to be clever with words. It epitomises politicians."
Earlier this week Mr Mitchell told Anglia News that requests for time off don't go through his office, but ultimately have to be signed off by the whip for absences. He wouldn't be drawn on whether he had informally discussed Mrs Dorries taking time off.
Responding to criticism about leaving her constituency, Mrs Dorries said that she has set up a temporary office in her hotel room in Australia to deal with constituency work. She says she also worked all the way through her summer, when other MPs took time off.
After just over a fortnight in the jungle Nadine Dorries - MP for Mid Bedfordshire - was the first to be voted off.
Her trip to Australia may have caused controversy but she says she has no regrets:
"What I know is that 12 million people watch this programme and I reckon out of those people a handful are probably MPs and people in the Lords and it really is important, I think, that what MPs realise is that you need to go where people go and understand why they go there."
It's caused plenty of controversy, and certainly made the headlines, but Nadine Dorries's stay in the jungle has proved to be shortlived.
The Mid-Bedfordshire MP was tonight the first contestant to be voted off this year's 'I'm A Celebrity Get Me Out Of Here' after just over a fortnight.
But despite being criticised for taking part in the show, she said she had no regrets.
Nadine Dorries was the subject of debate in the House of Commons today.
Deputy Prime Minister Nick Clegg admitted the "devil is in the detail" about how to define serious wrongdoing.
"I never thought that disappearing to a jungle on the other side of the planet would be one of the things we would have to grapple with on this recall issue," he said at Commons questions.
Mr Clegg said a new poll should not be triggered for frivolous reasons or for political point scoring, and that 10% of constituents would have to sign a petition demanding a recall by-election.
Mid-Bedfordshire MP Nadine Dorries' appearance on I'm A Celebrity... Get Me Out Of Here! shows why MPs should face a recall by-election if they commit serious wrongdoing, the Commons heard.
The Tory MP flew to Australia earlier this month to take part in ITV1's reality television show.
Her decision to chew on Camel Toe rather than represent her voters met with widespread condemnation at Westminster, with politicians urging the Government to speed up legislation so constituents can recall their MPs.
Liberal Democrat Lorely Burt (Solihull) said: "Life in politics can be a bit like a jungle; a popular vote may help to decide whether or not they should stay."
Nadine Dorries' jaunt in the jungle has got her suspended from the Tory party. But today her daughters said she got permission for time off from Andrew Mitchell, the former chief whip.
However, Mr Mitchell told Anglia News Mrs Dorries never asked his permission to go on the show and added that requests for time off don't go through his office.
