An abdication followed by an expensive coronation is definitely not what Britain needs right now, and while I don't have an issue with the Prince of Wales eventually rising to the throne, the Queen's steady reign is one of the most vital aspects of keeping the monarchy in place. A small hospitalization for some gastrointestinal problem should not make her resign.
I look forward to watching her Platinum Jubilee celebrations in 2022, by the way.
The British tradition in these matters is to have a regency if the monarch suffers from senility or madness. I'm all for having a regency start right now, but for tradition's sake it should wait until Charles is on the throne before a regent is appointed for him.
Lol.
