He should have demanded from the start that he wants William and harry plus families at center stage.
Why though? Harry and Meghan have publicly smeared his family and revealed lots of private information about them as well as spread rumours, which is such a betrayal.
H&M decided not to be working royals and have emigrated (Harry has). They are now Americans in the US and probably have loads more fun there than the royals here with all their stuffy traditions and restrictions.
Harry is mushroom happy and Meghan is free to build a clean living empire like Gwinnie.
M&H have found freedom and there is no need for them to tag along as unwanted extras and represent the monarchy when they have tried to undermine the monarchy for their own personal gain.
All is good, Lili and Archie have Doria who must be an awesome and super cool granny and Charles has his hands full as is with the 3 Wales kids and Camilla's grand children.
Not all families are close with all their grand children, especially when they live on different continents. Who knows, maybe the Sussexes will develop a better relationship with grandad Markle, which would be lovely.
If I could chose between the Wales' lifestyle and the Sussexes' I'd chose the latter.
