Accepting that political parties never deliver fully on their manifesto I think Boris did a pretty good job on the things that really matter to the country at large. Shame it was negated by a few lies and a bit of cake!
i thought that he did quite well considering the obstacles in the way, covid was a huge blow to the country at large and the government in my opinion did enough to keep us going in this crisis. I am sorry he was ousted by his own party, time for a new leader i guess.
In the dire circumstances that subsequently and very quickly arose after publication of that manifesto, it's totally irrational to expect those pledges to have been fully fulfilled. Yes, I think he did do well.
