Hi there, British Citizen here.
It's a bit boring from my perspective, I take the view that having the Queen is a benefit to us as she keeps politics out of the concept of the State. I know that 50% of the UK would hate a president Johnson, and the other half would hate a president Starmer. There's no win there.
She, Charles, William and George are really all that matter. Let's be honest, the three heirs aren't all going to die so everyone else is a supporting actor, NOT a star.
As far as Harry is concerned, He's stuffed by being the spare (as eventually Charlotte and Louis will be) we don't need them, they haven't got a real job and they can't live like we do.
I think we should let him and Megan get on with their lives and not get hung up on what they do and where they do it.
