VOICES clamoured for George Osborne to be evicted from his grace-and-favour countryside pad yesterday after the Treasury refused to reveal who the Chancellor partied with at the mansion.

The privileged Tory chancellor has had the use of Dorneywood, a 21-room Queen Anne-style house in the Buckinghamshire countryside, since his appointment in 2010.

He threw a decadent birthday bash at the property on turning 40 in 2012, and in 2010 he played host to disgraced News International chief Rebekah Brooks and her husband Charlie.

Prime Minister David Cameron revealed he had treated Lib Dems and the Qatari emir to posh dinners at his own country residence of Chequers.

His deputy Nick Clegg and Foreign Secretary William Hague, who shack up at the sprawling Kent estate of Chevening, disclosed details of their own sleepovers at the same time.

But despite numerous Freedom of Information requests, Mr Osborne’s Whitehall office has kept shtum over the Dorneywood guest list.

Last night Labour MP John Mann stormed: “The chancellor is given a flat in Downing Street and has several other homes, including in his constituency.

“Why did the Prime Minister think he needed another one?

“This arrangement of senior cabinet members being given grace and favour mansions to use as they please simply has to end. The lists of who visits these homes should always be made public.

“Only the Prime Minister needs such a home to use and even then it should only be used for official business, not to simply entertain his friends, cronies and donors.”

The Treasury’s wall of silence comes in spite of ex-Treasury minister Justine Greening promising during parliamentary questions in 2011 that a list would be published “in the usual way.”

A Treasury spokesman said: “The Prime Minister offered the house to the Chancellor of the Exchequer on his appointment for his private use.

“Accordingly the Treasury does not hold details of who has been entertained there.”

Mr Osborne and writer wife Frances are well-known socialites among London’s establishment circles. Ms Osborne’s first novel was compared to BBC costume drama Downton Abbey.
