The Guardian is doing live blogging, ConservativeHome are too, though currently they are focused on live optimism.

Seems 300 losses is the pivotal figure for Tony. More and he is in trouble, less and they will reshuffle and spin their way for another day.

Cameron’s Conservatives must get 200 gains or he is humiliated, 400 hundred and he is vindicated and “the project” is proven. In between is acceptable. Should be a good night for the LibDems as well.

Can’t find a LibDem or Labour live blogging session. The Guardian wil have to be a proxy for them. PoliticalBetting.Com seems quiet.

Guido will be live drinking and live posting on these three blogs, followed by live sleeping.
