Trilley:
The problem is that, as pointed out, we're potentially moving beyond breaking Covid rules to, at the very least, misconduct in public office.
Who's "we"? In any case, as I have said before, the people charged in almost every case of breaking covid regulations are those who organised the party or other event concerned. The police don't fine those who merely attended, however much you might hope otherwise.
And, before the usual suspects start up, that's not "defending Johnson", it is simply stating what has happened in numerous other cases.
