I think the Monarchy is reaching its natural end. The late Queen kept it all together and had a profound sense of duty, and she brought stability to her reign.
The King is very well meaning but ineffectual in keeping his Royal descendants (and his errant brother A) in line. He is not very well himself although putting a brave face on things.
The current crop of H, W, K, M, and all the other alphabet soup in and out of the RF are a different breed now. There doesn't appear to be anyone steering the ship anymore. So rebels will peel off and do their own thing. Well if the King can't tell them to F off and do your duty, I suppose they can do their own thing if they wish.
I hope I'm wrong though, so we shall see.
