I'd be gutted if Miliband stood down. He's done more to help the tories remain in power than any conservative has.
I feel a little sorry for Ed. I think he ran a good campaign, owning up to prior mistakes, being fairly transparent in his policies and Not being too negative. His image and the people's views on previous Labour governments seems to have been his downfall.
Still, he has to go. It's been a bad night for him.
