To reshuffle or not?
Cameron seems averse to reshuffles. In one way, this is commendable, ministers need time to grasp their brief and moving them every few years means they rarely achieve competence. But the downside is that catastrophic projects continue, because the minister's political reputations are nailed to them - that's been the problem with IDS and Universal Credit (good idea, woeful implementation). HS2 is another obvious example that needs to be swept away by a new broom.
