He has survived for now, but there is the problem of the Labour Party conference in September.
The Blairites will continue their plotting, but Lord Mandy, as long as he remains on Brown's side will probably out maneouvre and out bully them.
Whatever Labour do, short of a miracle, they will lose the next election. The electorate are just fed up of them. It would be a poison chalis to elect someone like Alan Johnson just to lose.
They will hope for the economy to improve in the next 12 months, and that expenses scandal will be forgotten. Probably lose, but not as drastically than if they triggered an election now, then elect a new leader with a clean sheet.
