And reply to poster above. No he's not the spare now. But growing up he was. He didn't have his life mapped out for him the same way as William. He has the same risks and responsibilities but there would always become the time he wasn't needed. Not easy for anyone.
Actually the Monarch still needs some support. There would always have been a role for Harry.
Currently the Queen has 7 full-time support, 3 of her kids and 2 spouses, plus William & Kate all full-time working Royals.
Before William and Edward were full-time, the Queen had Prince Philip, the Queen Mother, and can't remember if Princess Margaret ever did much in the way of Royal engagements.
It was as the Queen and Phillip were aging that William and Harry were asked to become full-time.
It will be a long time before William's kids will be asked to become full-time Royals. William enjoyed his years doing normal jobs inc the Air Ambulance he'll want his kids to have that same time.
So in say 10 years time if Charles is King, his siblings will all be in their 70s and 80s. William and Kate still working but their kids will still very young, in their teens.
There is definitely a role for Harry. But he doesn't seem to want to do Royal engagements.
The Queen also has the Duke & Duchess of Gloucester, Duke of Kent and Princess Alexandra. Between them they carried out over 500 engagements in 2019. They are all in their 70s and 80s so their contribution will get smaller, and end, over the next 10 years or so.
The loss of Harry and Meghan as full time royals means there are probably 600ish engagements (at least) that they would have covered. Add in the Andrew issue and Charles’ slimmer monarchy is looking very slim with 900 engagements less coverage.
I think one of the reasons William is so furious with Harry is that it is now, imo, unlikely that George, Charlotte and Louis will have the luxury of being non-working or part-time royals to their 30s like they were. George in particular is likely to be full time considerably younger.
In 14 years George will be 21. When William was 21 there was the Queen, Philip, Charles, Andrew, Edward, Sophie, Anne, the Gloucesters X2, the Kent’s x2, Princess Alexandra and occasionally Prince Michael of Kent. They had between them all picked up the patronage’s of QEQM and Margaret. That’s 12 full timers and PMOK part time.
When George is 21 there will be Charles (86), Camilla (87), Anne (84), Edward (71), Sophie (70), William and Kate. There’s not going to be another 10 years for him to fly helicopters, live in Anglesey and have a private family life imo. And that, I think, will massively piss off William.
