So there we have it. Brown has been to see the Queen, he's returned to Downing Street, and now he's announced what we all knew anyway: the election will be on 6th May. He was flanked by the entire Cabinet as he did so, like some grim school photograph. And he repeated the same lines from his Mirror interview this morning: the election is a "big choice", public service "guarantees", 13 years of "reform", and so on and so on. I suspect Blair would have smiled wryly at that last one, as well as at Brown's claim that he is "not a team of one, but one of a team". Either way, this is what it has all come to. The clock is ticking.
