I don't think "angst" is quite the right term for what many British people feel in respect of Boris (probably about 60% recent polls indicate can't wait to see him gone, with actual supporters only making up a minority of the remaining 40%). It's more a matter of just not trusting him to be honest in anything. Or competent in his job.

If he got back to being a public entertainer, free from any responsibility, he'd still be quite popular, I think. He can be very funny. A bit of a card.

I'd say that most people here, right across the political spectrum, are quite at ease with the idea of what gets called big government in a time of national emergency. In fact the kind of thing being referred to by that term doesn't need to be organised in a centralised way. A good part of nostalgia still felt about the last war period, including by people born many generations after it, is for a society which was in many ways very authoritarian.
