Gordon Brown has made a plea to voters not to risk change as he sought to salvage Labour's election campaign in the final TV debate before polling day.

The Labour leader, whose party is third in many opinion polls, warned against a Tory and Lib Dem coalition which would put "at risk" economic recovery.

David Cameron said Mr Brown was trying to "scare" voters and the Tories could deliver the "change we need".

Nick Clegg urged voters to "choose the future you really want".
