Tory rebel sends warning to Cameron.

Tory Rebel Peter Bone has today told tbg that the issue of gay marriage could be David Cameron's undoing as Tory Leader.

With Environment Secretary Owen Paterson and DWP Secretary Iain Duncan Smith also said to be uneasy its sure to set alarm bells ringing.

Mr Bone told tbg - "It is by no means impossible that David Cameron could be brought down as Conservative leader by his gay marriage plans."

"He is completely out of step with the mainstream of his party."

The news comes on the day a poll shows that Tory supporters are completely split down the middle on the issue.

A Downing Street source told tbg last night that were it not for pressure from Nick Clegg and Lynne Featherstone, the Prime Minister might not even have put forward the plans at all.
