Scottish Tory conference: PM Cameron outlines his 'ultimate nightmare'

David Cameron has described his "ultimate nightmare scenario" were Labour and the SNP form a coalition following May's general election.

The Prime Minister told delegates at the Scottish Conservative Party's conference in Edinburgh: "A unique unprecedented coalition of people who would like to break up our country and the people who would bankrupt our country.

"The only people who can stop them are us, the people in this room."
