I personally think that Boris Johnson, Matt Hancock and Professor Chris Witty look really scared
They are out of their depths and know that history will probably judge them unfavourably. I don't think they are malicious or playing an evil game with ulterior motives. They are just not the best people for the job (or at least the first two aren't). The political ladder filters out so many talented people and lets the entitled, butt-lickers, or the plodders make their way to the top.
Johnson - pretty useless for anything but procreation. Apparently he used to be funny. Just go take some pre-paternity leave but don't infect Carrie or baby N (where N = an integer).
Hancock - mediocre. I think he is trying hard and his heart is in the right place. Less useless than Johnson, but that's not saying much.
Witty - means well. Late career collector of initials after his name. In another age he'd be selling encyclopedias or cleaning products door to door, but has risen through the advisory ranks. I think he's the most competent of the three, but has fallen into a herd group-think shared by others at the top of his field government linked medics. Note how many a step or two below him with fresher qualifications are increasingly voicing their disagreement.
I'm not making party political points. I don't see much stature or competence in other parties. Oh, and I've never missed Theresa May and Jeremy Hunt so much. In which alternative reality should I be putting forward that thought?
