Gordon Brown has said he will fight to maintain a Labour government, insisting he can still "turn it around".
Following news that the Sun has withdrawn its support for Labour, the prime minister told the BBC he is still confident the party can win a fourth term.
He said voters would see that "the vision of the future that we have for Britain is about the hard working majority".
And he added that the Conservatives are still like the party of the 1990s "that caused so much damage".
His comments came as a YouGov poll for Sky News, carried out earlier this week, put Labour on 30 per cent of the vote, compared to the Conservatives' 37 per cent and 21 per cent for the Liberal Democrats.
As part of 'operation fightback', Brown announced a number of new policies at the Labour conference in Brighton this week, including more free childcare for families who need it most.
After the prime minister was criticised for his failure to discuss Afghanistan in detail during his keynote speech on Tuesday, Labour are hoping to undo the damage when defence secretary Bob Ainsworth sets out the party's position on the situation later on Thursday.
