Labour has pushed ahead of the Conservatives in the wake of Chancellor George Osborne's comprehensive spending review, according to a new poll.
The survey in The Independent puts the Tories down five points since a similar poll a fortnight ago on 35%, trailing Labour on 37% (up three points).
It was the first time a survey by pollsters ComRes has put Labour in the lead since Gordon Brown's 2007 "bounce" when a surge in popularity led him to consider a snap election.
And it was the second mainstream poll for a national newspaper to show the Tories slipping behind Labour since the October 20 spending review, in which Mr Osborne announced £81 billion in public spending cuts.
Liberal Democrats were up two points since a fortnight ago, on 16%.
But the poll had bad news for Lib Dem leader Nick Clegg, finding that just 60% of voters who backed his party in the May General Election would do so again, while 27% said they would switch to Labour.
By contrast, 95% of those who voted Tory in May and 93% of those who backed Labour would do the same again if an election was held now.
:: ComRes polled 1,000 British adults for The Independent on October 29 and 30.
