So, Elizabeth II (the Queen) has died and Charles III is now the King.
It was widely reported that the day of her funeral would be a quasi-national holiday "day of mourning" but that, crucially, this wasn't an official bank holiday and that businesses were totally free to interpret this how they liked. In all likelihood, this would have meant nobody actually got the day off unless their boss was a raging monarchist.
However, since then, the King has "pronounced" that the day will in-fact be a bona fide bank holiday with all that entails. I've seen other reports that suggest he merely "approved" it.
So, that begs the question, did the King decide it was going to be a bank holiday and pronounce it so? Alternately, did Liz Truss decide it was going to be a bank holiday and then the King just signed off on it? A final option, did the King decide he wanted it to be a bank holiday, "suggested" to Liz Truss that it should be and she just went along with it?
Given Liz Truss is notoriously tight-fisted when it comes to bank holidays, I'm struggling to believe that this originated from her.
Also, I think understanding where this came from is important, as if the King did just proclaim it, he's already meddling in politics and this could be a sign of worrying things to come.
