Blair building for his departure?

Very interesting post by Nick Robinson on his blog today.

He picks up on Tony Blair’s attacks on David Cameron branding him as a lightweight who will be defeated by a hard punching Labour heavyweight.

The fact Blair took the fight to Cameron and did a fairly good job of it, leads Robinson to speculate Blair could be building for an earlier departure than we think.

It is certainly the case that the only option Blair has left to go out on, is surprise. I still think he will be PM come Christmas, however he could be gone by March.
