Some post-match analysis

Overall impression of PMQs was one of disbelief. Cameron had plenty ammunition but seemed on first viewing to lack the stomach to use it. Nick Clegg fired off some good shots, but got laughed down by Labour's backbenchers. I smell some Hubris coming their way. I think Cameron is playing a tactical game here, and from an electoral perspective I can understand why.

Spectator has a pretty good breakdown, which I think makes good sense. What I think they're missing is that Cameron doesn't want a mortally wounded Brown, just a grazed one. I suspect we just saw a calculated salvo aimed not to kill. If Brown has confidence he'll stay in No. 10, and that means a much surer chance of victory for the Conservatives at the next General Election. A new leader means facing Labour in a honeymoon period of sorts, and that might be enough to rescue a few seats.

The fact Brown won't be called on an election shows he still thinks he can turn things around and improve on the polls. He'll hold out as long as he can in the hope his political currency can rise. Cameron wants an election now because that would mean facing Brown, not a new Labour leader. For him, the longer Brown holds out, the greater risk someone in Labour will grow the cojones to challenge him.
