I've never had any faith in them. If they served any purpose, Her Majesty would have sacked Boris Johnson herself (and chopped his head off for good measure); he was her servant, after all. I had to laugh that King Charles was practically forced into a T-shirt that said "Just Start Oil", it was almost funny the way that even the King had to say things it was well-known that he didn't agree with.
And I've said before, I think lots of things are not as they seem. It's amazing how Her Majesty lived just long enough to reach Platty Joobs, and her mother lived just long enough to reach 100. Perhaps the film The Queen was the dress rehearsal for Dame Helen Mirren, or somebody looking similar. For all we know, the latest might be the lesser of what has been covered up, they just botched this one, or the botching is to distract us from something else. Is the King still appearing now and again, even if Kate isn't? (I can't be bothered to watch and find out, I refused to watch Golden Joobs, Diamond Joobs, Platty Joobs, the funeral, and the coronation.) Things may not be as they seem. 🤔 Remember that they have access to the best illusionists, impressionists, magicians and spin doctors that money can buy.
(And because this is Mumsnet, the above is pure shameless satire.)
