Prime Minister Gordon Brown has told the BBC he can still "turn it round" to win an historic fourth term for Labour.
He denied that the Sun newspaper switch to backing the Tories had derailed his last conference before an election.
A YouGov poll for Sky News put Labour on 30%, compared with the Tories' 37% and Lib Dems' 21%, suggesting a boost from Mr Brown's speech on Tuesday.
Mr Brown has sought to present Labour as the "underdogs" at a conference the party has dubbed "operation fightback".
He also unveiled a string of new policies - including more free childcare for poor families paid for by ending tax breaks for the better-off and a crackdown on anti-social behaviour - in an attempt to convince voters Labour has not run out of ideas.
