The Blairites may be celebrating Gordon Brown's downfall more than the Cameroons

A year ago, Gordon Brown was riding high in the polls, and there was open talk of a snap general election. Even his critics were heaping praise on him. He was quite simply the Tories worst nightmare.

Twelve months later, the Tories worst nightmare may be his downfall, if you follow Janet Daley's logic: Labour's constitution makes it difficult but not impossible to remove their leader. Should they have a leadership contest, they may well end up with a young Blairite leader such as James Purnell or David Milliband. They could still lose the next general election but it may well be an honourable defeat rather than a wipeout. And with a party of inexperienced Tories in inheriting of a battered economy, David Cameron may end up leading a one term government. If I was in his shoes, I would be a little nervous.
