Also Harry has no horse in the race between Charles and William. Perhaps he can offer insight and support to HMQ on things which might concern her re Charles and William and the future Monarchy.
Perhaps he holds insight on the Charles William relationship that can help her.
I know the Red Tops currently have us believing that William loves Camilla and Charles but I see no sign of it. ( Same with Harry )
William may also behave very differently once he has the vast fortune of the Duchy under his control. Charles is able to agree or curtail William’s spending and movements at the moment. That all changes upon the death of HMQ.
I am unsure William particularly wants to wait until middle age to become King. With the right Press pressure will the British Public?
The reason Harry was able to meet HMQ without the world knowing was that either William or Charles did not know about the meeting before it took place.
If Harry met Charles - big if. The suggestion then is that leaks are coming from staff briefing the press on behalf of William.
If Harry met neither, the suggestion is that neither they, nor their staff, are to be trusted with information.
It is very unpleasant.
There were prior suggestions that it was palace courtiers leaking information regarding Harry - this visit shows that HMQ’s staff are discreet when she wishes them to be.
This is why the news of the visit was leaked.
When Harry wished to have a mixed role outside the Royal Rota - ‘Mexit’ - these conversations were taking place and progressing secretly until Charles insisted they were put in writing.
Once in writing they were immediately leaked to Dan Wooton.
Speeding and cementing the process and allowing the Press to shape the narrative - largely it was in favour of stolid William who could no longer hold up his feckless brother.
This lack of security of information, deliberate leaking, demonstrates an impact on Royal Protection too.
