Communicate Research in the Indie has got Labour boosted by the budget - with the Tory lead dropping from 11% to 4% (Con 35% - down 5; Lab 31% - up 2; LD 20% - up 3).
The detail shows Labour up a lot amongst key groups of voters - up 9% amongst skilled working class C2s and up 5% amongst junior white collar C1s, but down 7% amongst the least well off DEs - all of which is a fairly logical reaction to the way the Budget has been presented.
The Indie says:
"Mr Brown's Budget may have halted a slide in support for Labour among the party's traditional supporters in recent months. The proportion of these who say they will vote for the party has risen from 76 per cent to 79 per cent since last month, while the Tories' level of "core vote" support has fallen from 91 per cent to 87 per cent."
