They are all looking nostalgically at Margaret Thatcher, who was a workaholic and got by on four hours sleep a night. If she could do all those wonderful things (their opinion, not mine) on so little sleep, then someone who does not overwork and gets a decent night’s sleep is going to do bad things, or at least that is their twisted logic. Don’t mention Johnson, who didn’t do much work and made a right mess of things, or Truss, who is reported to be a right workaholic and made a right mess of things. It really is just a desperate lashing out with any criticism that might influence somebody, somewhere: they are getting desperate.
