Thus far BJ hasn't covered himself in glory. However no previous prime minister in living memory - and my political memory goes back to Heath/Wilson - has had to cope with anything like the pandemic. The UK was almost completely unprepared for the pandemic, despite the possibility being one of the red flags raised only 2 or 3 years ago. (Others misjudged it too - the French were busy destroying 'excess' PPE in January this year, to save storage costs … until the Deputy PM found out.)
To me Boris's style is suited to sunny days and boosterism, when with the pandemic we need something more sober and serious. Also, he seems loathe to take awkward decisions, and has several times had to contradict himself quite quickly over measures to contain/control Covid. His libertarian impulses sit awkwardly with an unthinking virus, which gets on with what it does - and varying forms of isolation or quarantine are the only weapon, short of an effective vaccine.
I think he was quite wrong to miss the opportunity offered to postpone the Brexit deadline, so he has landed the government - many ministers being rather lightweight, seemingly chosen for political loyalty rather than competence - with dealing with two very serious issues at the same time. The chaos in Dover today could well be a foretaste of worse to come.
His government, and he personally, have handed contracts and office to old pals, cronies and donors, wasting fabulous sums which could and should have been spent more thoughtfully. His defence of Cummings in early summer was an absolute disgrace, and his Lords appointments look like the most egregious cronyism. The possible good news is that he doesn't appear to be enjoying any of this, and I suspect will depart (to the Lords, natch, on nice allowances) once Brexit in particular is done, perhaps after a bit of an interval. He has apparently claimed money troubles, the PM's salary being well under what he is used to, and he has expensive commitments ...
