Mr Bean

Cameron was very effective today at PMQs, but Vincent Cable was lethal, describing Gordon Brown's

remarkable transformation from Stalin to Mr Bean.

It's an image that I predict will now take hold. It's amazing how one phrase in one sentence at PMQs can be devastating.

UPDATE: It seems Vincent Cable is not the first person to have made the allusion. In his Express column of 19th November, Leo McKinstry wrote:

As with Mr Bean, Brown is a major social embarrassment to those around him.
