Because it is our business that the future queen is in hospital.
Seriously? Why? does the government functioning depend on her not being in hospital? As the future queen of ... nothing at all. Do people understand how the UK is governed?
Even the queen regnant couldn't stop Boris Johnson making her prorogue parliament - later deemed unconstitutional by the supreme court. They are utterly irrelevant to the government of the UK - except for the ceremonial bits that get media coverage but mean nothing. They do PR for the nation to justify their immense privilege and wealth.
But being the wife of a guy doing PR at an inflated rate for a country, still doesn't entitle anyone to know her private medical history.
this thread is like watching the wah wah wah of Diana's death all over again. These people are nothing to you just as you are nothing to them.
