Gordon Brown’s keynote conference speech today is the most important speech of his life. It will determine whether he can manage to hold on to power for much – or any – longer.

If he wants to hold on until the next general election, it needs to be a real blaster of a speech – and be seen as one by loyalist and rebel MPs alike, as well as the party faithful and the media.

A tall order indeed. Is he up to it?

Somehow I doubt it.
