A state led by Sunak, Gove or Truss with reforming zeal would be an unpleasant place to live. But it’s also damaging to be governed by intellectually deficient, personally ambitious, corrupt or simply uninterested ministers. Fewer ministers than ever care about their departments, as the internecine vortex of Westminster and dreams of a slot on Question Time suck in most of their attention. This has been especially true since 2016, though the problem is of longer gestation. It doesn’t entirely explain why Britain, after twelve years of Conservative government, is run-down, stagnant, expensive, underpaid, unequal, corrupt, socially fractured, backward-looking, hungry and fearful. But it doesn’t help. It will take far more than dislodging Johnson to change that.
