Dorries Investigated Over I'm A Celebrity Fee By Sophy Ridge, Political Correspondent Nadine Dorries is to be investigated by the parliamentary watchdog after allegedly failing to register a payment for appearing on I'm A Celebrity ... Get Me Out Of Here. The Conservative MP told Sky News she was "100% confident" she would be cleared by the Parliamentary Standards Commissioner. Under House of Commons rules, MPs must register any external payments within 30 days. Ms Dorries said: "I'm 100% confident I will be cleared. If I was paid a fee I would have declared it. If I haven't declared it, I haven't been paid it. A complaint made to the parliamentary watchdog was accepted this week. It is understood that the Mid Bedfordshire MP is the director of a personal limited company, and has said she will declare money that she chooses to take from the firm. Rob Oxley, from the Taxpayers" Alliance, said: "It is absolutely right that MPs have to publicise any additional income they receive for other work. It helps constituents to make an informed judgement about their MP's performance at election time. Mid Bedfordshire residents already have the right to feel let down after Nadine Dorries abandoned them for the jungle - but if she has failed to be straight about what she was paid for the caper, that will only add insult to injury. Ms Dorries" decision to appear on the ITV reality show has already proved controversial. She was suspended from the Conservative Party last November for flying to Australia, but had the whip restored by Sir George Young after reportedly apologising to him. She has defended her appearance on the show, saying it was a way to bring politics to the attention of a younger generation. The MP was the first contestant to be voted out of the jungle by television viewers.
