A government reshuffle has two purposes. First, it is an opportunity to remove ministers who are failing to perform their duties effectively and replace them with ones who might do better. Second, it is a chance for the Prime Minister to signal has political priorities and express the kind of character he wants his administration to have. The official line from the heart of government is that today’s realignment is very much about the former goal. The coalition is said to be moving into a tough phase of implementing complex policies across a range of portfolios and the PM puts a premium on managerial competence. As one senior aide puts it rather indelicately: “This is all about Cameron getting rid of bad ministers.”
Well, they are hardly going to say it is all about Cameron trying to shore up his position in a party that has acquired a dangerous appetite for rebellion. Nor will it ever be admitted that the noisy rearrangement of cabinet chairs is meant to symbolise seizure of the political initiative after the disorderly parade of crises that characterised the months running up to the summer recess. But that of course is a large part of it.
