Cameron vs Brown

Video of yesterday's assault on Gordon Brown. A friend emails:

By god, Cameron destroyed Brown. Michael Howard on the Newnight panel astutely pointed out that Blair would have made a self-deprecating remark that would have admitted the charge, but defused the pressure. It is so true. Remember Blair's remark about Cherie and the allegation that she shouted 'That's a lie' whilst watching GB's speech last year where he paid tribute to TB? Blair came out with the line 'At least I don't have to worry about her running off with the next door neighbour.' It admitted the fundamental truth, but killed the story dead.
