As a conservative unionist who thinks that Boris”s time is up, I think he won’t be viewed as badly as some people think.
He got Brexit done, he won a huge majority and his instincts regarding binning the pandemic regulations are spot on.
Unfortunately, he got Covid quite badly which put him out of action for a while and he had a poor bunch of people advising him. For a ‘big picture ‘ person to succeed you need some great detail people in the background.
May was great on detail but had no vision and Cameron was just useless.
Anyway, the story isn’t quite over yet so time will tell.
