It sounds minor but I think the fact that the public calls him “Boris” is actually a problem. He’s not our mate, and it lets people forget that he’s meant to be an elder statesman and behave like one and be effective as one.
He’s a good campaigner but a bad governor and he gets away with so much because the public feel this bizarre affection towards him when really he’s plainly doing a shocking job and letting us all down. It’s of course a stupidly difficult job, but he chose it and regardless of whether anyone else would do better, he is bleeping it up.
Calling him Boris instead of PM Johnson, Mr Johnson or just Johnson always has the effect of diminishing the seriousness of what’s happening. He’s not some naughty schoolboy or that character from work. He’s the Prime Minister. I wish people (generally, not directing this to anyone specific here) would realise this instead of just watching him bumble his way around the most significant challenges of our lifetimes.
