POLICE have been urged to examine Maria Miller's expenses amid growing anger over the way MPs watered down a damning independent report that suggested she should repay £45,000.
Labour backbencher Thomas Docherty called for Scotland Yard to intervene after the cross-party Standards Committee ordered Ms Miller to apologise but overruled sleaze watchdog Kathryn Hudson by deciding she only needed to hand back £5,800 in overclaimed mortgage interest.
The rows has sparked demands for Mrs Miller to be sacked or stripped of responsibility for shaping a new press regulation system.
Speaking on a visit to Devon, British prime minister David Cameron said: "It was found she had made mistakes, she accepted that, repaid the money, she apologised unreservedly to the House of Commons so I think that we should leave it there."
The standards committee released a joint statement with Ms Hudson describing the situation as "complex" and stressing Mrs Miller had been rebuked for failing to co-operate with the investigation.
Mrs Miller has been accused of making a "contemptuous" 32-second apology on the floor of the House on Thursday.
The inquiry was launched in December 2012 following allegations that Mrs Miller used some £90,000 in expenses between 2005 and 2009 to fund a house where she lived with her parents.
The commissioner found Ms Miller over-claimed by £45,000 for expenses towards mortgage interest payments and council tax.
However, the committee decided that she needed to pay back just £5,800.
It accepted Ms Miller's explanation that she had inadvertently allowed her claims to remain the same when her tracker mortgage fell with interest rates in 2008.
Mrs Miller sold the London property, which was purchased for around £235,000, for just under £1.5 million in February.
Mr Mann - whose complaint triggered the investigation - said: "A self-regulating group of MPs has ignored and overruled the conclusions made by the independent Parliamentary Commissioner for Standards".
Mr Mann also called for Mrs Miller to be stripped of her responsibility for shaping a new press regulatory system.
