Ben Brogan reports that George Bridges, David Cameron's former campaign manager, has quit, It is a loss, he's a great guy and had a hell of a tough job. Being in charge of campaigning for Scotland and the north is like being made head of the Saudi Arabian division of Guinness. I gather his departure was not to do with a clash with Andy Coulson, and that he had been growing steadily disgruntled with the Cameroon operation for some time. So when Coulson was appointed, Bridges didn't even know (as Francis Elliot tells us). A rather puzzling move: Cameron needs all the talent he can get right now.
