Culture Secretary Maria Miller is expected to face intense pressure when the results of a lengthy investigation into her use of taxpayer-funded expenses are published today.

The Conservative Cabinet Minister was reported to Parliament's sleaze watchdog in December 2012 for using the second home allowance for MPs to pay for a house in Wimbledon where her parents lived.

Mrs Miller claimed £90,718 - almost the maximum permitted - between 2005 and 2009 towards mortgage payments, bills and other costs relating to a house in Woodside where her mother and father had apparently been living since 1996.

Reports last week suggested the Basingstoke MP and former Merton Conservative is likely to be forced to repay thousands of pounds and will be made to apologise for not co-operating with the inquiry.

Mrs Miller is said to have since made a profit of nearly £1.5 million on the property at the centre of the investigation.

When the probe was launched Prime Minister David Cameron declared his ''full support'' for Mrs Miller.

''Maria Miller does an absolutely excellent job as Culture Secretary and she has my full support," he told reporters at the time.

" A newspaper has asked her a number of questions. So far as I can see, she has got excellent answers to all those questions."

Asked last night if Mr Cameron still had full confidence in Mrs Miller, the Prime Minister's official spokesman told a regular Westminster media briefing: "Yes, he does."

The cross-party Commons Standards Committee will publish its long-awaited report into Mrs Miller's claims at 11am.
