Now that one minister and a handful of ministerial aides have resigned two groups of people face a decision today.
The Brownites: They are accused of attempting a coup by Tony Blair's friends. If that's right they have to decide if they are going to follow it through. Will this become not just this group of relatively junior folk - but senior cabinet ministers, as they did with Thatcher in 1990, saying to the PM, "you need to go and you need to go soon"?
The Blairites: Can they bring themselves to work with Gordon Brown to make a reality of this awkward phrase "stable and orderly transition"? They haven't so far for one good reason - they don't want Gordon Brown to become PM. They wanted their man to stay in office so someone else could emerge. If they can bring themselves to work with Brown, perhaps he'll call the dogs off. Perhaps.
Until we know the answers to those two questions, we can't know whether Tony Blair will be here for eight more months as he hopes, or just weeks.
