Senior Labour figures have warned that Gordon Brown could face a delegation of “men in suits” pressing him to resign if the party loses the pivotal Crewe by-election this week.
With the campaign descending into accusations of dirty tricks, discontent with the prime minister’s leadership has begun to spread.
“There has been a shift in mood,” said one MP. “Mutterings about regime change used to be confined to the fringes of the party, but now there is a more widespread view that Gordon will have to go unless he can win back public support.”
