I agree that piece from Richard Eden is not telling us much we didn't already know... except maybe for this intriguing quote:
A friend of the royals tells me: ‘Their Majesties will not see Harry and Meghan while they are in the States, but don’t read anything into that. The King hopes to see more of his son and spend time with his grandchildren. This will happen in Britain before long.’
The main question being, a friend of which royals tells you? Because I could imagine it coming from Montecito, which means we can only give it very limited credence. Plus, I can see Harry wanting this, and can see him saying his father wants this... but would Meghan even be on board?
On the other hand it would be both more credible, and more surprising, if this friend of the royals was close to, and speaking about, Charles. In that instance, would Camilla ever be involved in such a rapprochement? I don't think so.
So it seems not at all obvious who is sending out this message, Harry or Charles, and how much it is based on an attainable future reality.
