According to Sky News, the reshuffle is already underway, as if that might make people more likely to vote Labour tomorrow. Nick Robinson is reporting that John Reid was offered Home Secretary last night but turned it down. He also said there were rumours which he couldn't substantiate (would I get away with that?!) that Alistair Darling has been offered the job and he too turned it down. So, Blunkett, Johnson, Denham and Woodward seem to be the most likely replacements.
The biggest decision for Gordon Brown now is what to do with Alistair Darling and David Miliband. Darling seems to be making it clear that if he can't stay as Chancellor, he will quit the government. David Miliband has also signalled heavily that he wishes to stay as Foreign Secretary. Having been seen as having wimped out of standing up to the PM in the summer of 2008 he won't make that mistake again.
One other interesting scenario is whether any of Hazel Blears' close allies decide to follow her lead. I wonder, for example, what the future holds for Caroline Flint, the Europe Minister, who spoke out in Hazel Blears' defence last week. In theory she should be a sure fire certainty for the cabinet, but I wonder whether she might a) resign or b) be fired.
