You mention an interesting point about the Queen.
It's why I automatically disbelieved Tom Bower's "Thank God Meghan is not coming" story during Philip's funeral. In fact, that story is the only one I recall where there was gentle push back by those close to the Queen, someone denied it, and observed, wryly, that it is hard to imagine that Meghan was the first thing that popped into her head after the death of her beloved husband of years and years.
And that leads to another observation.
After Diana died, the Queen was hugely unpopular, and those years were pretty awful for her, and the rest of the family. But did she hire a Mark Bolland or an ex Daily Mail editor or cosy up to the Morgans and Clarkson types? No, she kept her head down and got on with it. And died beloved and dear to her "subjects" and respected around the world.
That respect, that affection was earned, not manipulated by hiring ex Daily Mail staffers or throwing others under the bus to make herself more popular.
She learned a huge lesson from that ghastly BBC documentary. I believe that her only meetings with the press was when they met her on public engagements. She did not have to manipulate the media as her son and daughter-in-law have done, and keep doing.
I keep saying it: the rot set in when Charles needed to discredit Diana to rehabilitate Camilla.
