Gordon Brown has been dealt a heavy blow after a poll showed his personal ratings falling dramatically and Labour slipping further behind the Tories.
The YouGov survey for The Sunday Times found Labour trailing David Cameron's Conservatives by six points - double last month's margin.
While the Tories are unchanged on 41%, Labour have slumped to 35% (down three).
The Liberal Democrats, on 13%, have gained two points in the wake of Sir Menzies' Campbell's resignation as leader.
The poll also suggests the Prime Minister's individual standing has declined considerably amid sustained criticism of his 11th-hour decision against calling an autumn election and heightened consumer fears about the economy and house prices.
His net approval rating in the YouGov survey has fallen from its height of 48% in the summer to 30% last month and minus 10% this.
A month ago, 59% thought he was doing a good job compared to 29% who said he was doing badly.
Now those thinking he is doing well have fallen to 33%, against 43% who feel he is doing a bad job.
