Conservative MP Nadine Dorries will face an official investigation after abandoning Parliament to join ITV reality show I'm A Celebrity Get Me Out Of Here.
The Tory representative for Mid-Bedfordshire - who is the first ever standing politician to take part in the show - has already been suspended from the party.
But now a probe in to her absence will be launched by the Parliamentary Commissioner for Standards John Lyon, who has previously investigated the infamous expenses scandal of 2009.
Mr Lyon will decide whether or not she has broken rules by accepting a reported £40,000 fee for her involvement, which will see her away from her constituency for up to a month.
A spokesperson for his office confirmed: "We have received a complaint. This is being considered in the usual way."
Dorries has experienced a backlash for her decision to enter the jungle. Prime Minister David Cameron weighed in to the row yesterday, saying: "If you’re in the Australian jungle you can’t really be representing your constituents."
But despite this, the 55-year-old has pressed on, hoping to use the opportunity to promote her political views and the work of MPs.
I'm A Celebrity 2012 starts this Sunday at 9.00pm on ITV1.
