I never understood Princess Anne’s statement about who would cover all the engagements if there is a slimmed down monarchy because it seems obvious to me in that scenario that the number of engagements should be slimmed down too!
Speaking as a Republican, and to answer the original question, I think it is the end of an era and the monarchy should be wound down.
Republican countries like France have a system whereby state power is devolved downwards and the locally elected Mayor, who is accessible and accountable to their local community, is available to carry out local engagements such as being in attendance at ceremonies of remembrance or opening new hospitals, and that seems a pretty sensible way of going about things to me.
I also think the system of having an unelected family representing us is problematic at its core because as we have seen, some members are reasonably good at the job and others are just average or entirely unsuitable, eg Andrew.
But mainly, I think having a Royal family as opposed to an elected Head of State allows there to be far too much obfuscation between what is private wealth and private inheritance versus a transparent, accountable allowance or salary to carry out the role, which is subject to thorough scrutiny.
The King after eighteen months as monarch and many years in preparation for the role, has not made any attempt to slim down their excessive number of residences as far as I know.
And obviously, if you only have to house one elected Head of State and their spouse, and possibly their dc up to the age of adulthood, then they will only need one large flat in Whitehall somewhere and one country residence like Chequers where they can entertain foreign dignitaries.
There won’t be all of these family members and cousins living in vast estates and expensive London grace and favour flats.
If you take the example of the King’s youngest brother, Edward, and his wife Sophie, they live in a house worth £30 million pounds which seems to me wildly excessive and extravagant. Why do they need a house with 120 bedrooms to carry out their role? Their argument will presumably be that the estate was a “private” gift from QEII. But the upkeep is paid by the Sovereign Grant is it not? No doubt someone will correct me if I am wrong.
