He recently brought in Alan Duncan who was meant to clean up the perception and expense scandals within the party, to try and draw a line under this once and for all.

It was discovered over the weekend that the man put in charge of this clean up operation (which had the full backing from the shadow PM) has himself been caught out in flipping his own home. Tory MP Alan Duncan claimed £63,000 in mortgage interest on his designated second home, even though he had owned the property outright for over a decade.

This will be a huge blow for David Cameron who put Mr Duncan in charge of sorting out these types of scandals within the party.

Mr Duncan, who is shadow leader of the house, apparently fiercely denies any wrongdoing. But how can he realistically defend himself when he was claiming mortgage interest on a second home, when he owned the property outright.

He bought his country house in 1992 without the need for a mortgage, saying it was his second home. It was not until 2004 that the multi millionaire Duncan flipped his mortgage and took out a £271,000 loan on his country house. Since then he has claimed £1,400 a month in mortgage interest on his mansion in Rutland.

Mr Duncan claims he has not abused the system and is a victim of a witch hunt. He has claimed £127,658 over the past six years for his second home but has only paid back £5,000 for gardening expenses.

Former Labour chief whip Hilary Armstrong and ex-Europe and defence minister Doug Henderson both announced yesterday they would quit the commons over the next general election.

Maybe Mr Duncan should make his announcement also, along with a few others, and we can finally clean up political expenses greed.

Cameron’s clean up man caught flipping second home.

Ever since the full truth of the MPs expense scandal came to light, David Cameron has been quick to try and sort out the mess caused by his own party in the public eye.
