So rather than nitpicking about that, let's move forward and note that you accept that he was disobeying the rules for which he as PM carried major responsibility.
No. The rules for which he held joint responsibility. As I keep saying, we do not have a dictator nor even a president in this country, so trying to glam up Johnson as some sort of star is a mistake.
Is that the conduct of a good Prime Minister, especially at a time of major crisis for the country?
Of course not. Why do you even need to ask?
