I never know which equerry story people are referring to? The Johnnie Spencer one? Or the more salacious one about Diana saying that Prince Charles was in love with his valet?
At least one of his valets made it to equerry status I believe?
If the former, there was talk of Johnnie Spencer becoming a suitor of Princess Elizabeth before he became an equerry to her when she was married, because she wrote to him while he was on active service during the war. So it’s not inaccurate. You can easily find this documented in several history books.
As for the latter, who knows? It could have been a joke? It could be true? CS is simply reporting what Diana said. He is not making a judgement about it.
As for the Frogmore burial story not everyone is in agreement on this board about the royal protocol surrounding that and far more informed voices than mine have explained why CS has said this. I suppose it might depend on Diana’s HRH status at the time which was offered back to her? We don’t know the strict sequence of events?
I suggest everyone bears in mind that serialisation of the most interesting snippets of a book can massively distort the impression of the whole!
I for one am looking forward to reading it in its entirety.
