London mayor Ken Livingstone will resume campaigning after a video "gaffe" on April Fool's Day threatened to distance him from the Labour elite.
Mr Livingstone will attempt to draw attention to his housing strategy for the capital during a walkabout in north London on Wednesday.
On Tuesday, in an apparent out-take from a campaign video posted on the internet, the mayor was seen describing his proudest political achievement as "smashing" New Labour.
In the footage Mr Livingstone is asked: "Looking back on your political history, what would you say was your proudest moment?"
He replies: "Oh, it's taking on and smashing the New Labour machine in 2000 when Tony Blair wouldn't let me run for mayor, and just grinding them into the dust."
The comment risked provoking anger among senior figures in the Labour Party.
Mr Livingstone's camp has reportedly insisted the video was an April Fool.
Minister for London Tessa Jowell, an arch-Blairite, is closely involved in running his campaign to be re-elected for a third term next month.
Mr Blair fought to block Mr Livingstone from becoming Labour's mayoral candidate in 2000.
But the former prime minister was embarrassed when he promptly left the party and ran successfully as an independent. Mr Livingstone rejoined in 2004, shortly before securing his second term in City Hall.
