This week really is to be packed with events. Quentin Davies has resigned the Tory whip and defected to Labour. In doing so he has mounted a vicious attack on Cameron and his lack of direction. This is a coup for Labour. It puts the Tories well onto the back foot while they are already reeling. But beyond the tactical advantage, the message it sends is once again that Labour is the party of national government, taking decisions in the best interests of the country.
Perhaps not such a surprise that Tony Blair is to resign as MP for Sedgefield, though the timing is perhaps. He has seemed very much at home respresenting that constituency.
