Unbelieveable. It's going from bad to worse to apocalyptic for Labour. The latest news is that Tom Watson - a key Brown ally, and minister for digital engagement - is set to resign as well. The main question doing the rounds in Westminster is whether this spate of leaks is designed to undermine Brown; whether ministers, knowing they're going to be pushed, are jumping to create disarray. Or whether this is all part of the Dear Leader's mad plan. Whatever the reason, this is fast becoming one of the worst days of Brown's premiership: the day when it all, quite literally, fell apart.
