Support for Gordon Brown's Labour Party has slumped to its lowest since records began in 1930, according to an opinon poll.

The latest survey puts the Tories on 49 per cent - a massive 26 points ahead of Labour on 23 per cent.

Labour's support was even lower than the share of the vote it received in the local election mauling at which it lost hundreds of seats and lost the London Mayoralty to Boris Johnson.

And the poor poll results for the Government come less than a fortnight before Labour faces a crunch by-election in Crewe and Nantwich, a seat the Conservatives hope to win.

The Conservative score was five points up on last month, while Labour dropped three and the Liberal Democrats remained at 17 per cent.

Eight months ago, the same polling firm gave Labour an 11-point lead.

YouGov sampled 1,571 adults online between May 7 and 8.
