Gordon Brown Resigns.

I'll have more to say about this in the morning, but a deal between Labour and the Lib Dems becomes much more likely now that this has happened.

Wait for Conservative heads to start exploding in rage.

UPDATE:

The Tories have now responded and, for them, it reeks of desperation:

The Conservatives have made a "final offer" to the Lib Dems of a referendum on electoral reform as the battle to form the UK's next government heats up.

Tory deputy leader William Hague said he would offer Nick Clegg's party a vote on the Alternative Vote system.

It comes after Gordon Brown, who said he was standing down as PM, offered Alternative Vote and a referendum on proportional representation.

The Lib Dems must now decide which party they want to back.

The Tories never wanted to offer this much, but Clegg has forced their hand. They are now trying to force Clegg to accept their offer by claiming that, should he choose Labour, he will be allowing "a second unelected prime minister in a row".

Maybe they misunderstand our political system, but Cameron has also not been elected, that's why it's called a hung parliament. If Cameron had been elected, none of this would be taking place.
