Totally agree. I think there are far bigger fish to fry constitutionally, and if we were to have a ceremonial President like they have in Ireland, whats the point, we may as well keep a family to provide a Ceremonial Head of State and do their show pony bit, but they need to be properly scrutinised, and be made to justify why they want to do things like be exempt from legislation, and having papers hidden even though they relate to work done for the UK government, like Andrew Trade envoy role. If it is then granted, fair enough, but proper open debate about them in Parliament and in the press is essential.
Even though the hangers on will always exist, proper scrutiny from the press will hopefully mean they will think twice when approached by shady people. I don't see what is wrong with what Zara is doing- shilling off her links to the Royal Family- (she cant help being the Kings niece, and I don't want to support her to open a shopping centre- Harry and Meghan should have been allowed to do the same thing) but some open scrutiny from the Press would go a long way to stop them getting involved in dodgy dealings.
The problem is that they are none too bright as a family, so cant see that more scrutiny will benefit them and stop them getting into so much trouble. Their enormous entitlement means they need to be protected from themselves, but not as it is now, where they do something stupid then have to rely on an army of willing subjects to cover it up, but by having to think about whaether what they are doing is advisable. They would benefit from not being surrounded by obsequious forelock tuggers willing to do whatever it takes to protect them. So many of them don't know how to behave, or how to listen to advice maybe they need to be forced into it by knowing that what they do will be openly discussed in public.
