Well, it's nearly 3 o'clock, and what's becoming clear is that the assumption of anything like a uniform swing no longer holds. Sure, there is a tendency towards a swing in favour of the Conservatives, but in some constituencies, including Tory targets, the swing is very small, or even negative.
David Cameron is on camera and not smiling very much. There is a recount in Birmingham Edgbaston, which is clearly a seat the Tories need to win to get a majority.
It's going to be a long night.
