It would be interesting to see how - if at all - these numbers change now that Afghanistan has returned to the political foreground. The usual view is that the conflict receives far more support in Westminster than is does among the general public. But now that Nick Clegg has broken ranks, you wonder whether more politicians will call for the troops to be returned home, and whether that - in turn - will affect wider opinion. For his part, Gordon Brown is - rightly, in my view - pushing the case for our involvement in Afghanistan. He published a letter on the subject on Satuday, and he's expected to reiterate its main points in his Commons statement today. But will his support translate to more troops in the region? Well, this morning's Times suggests not.
