According to the Mail article, some allegation about Meghan being 'an opportunist' who was too old for Harry?
But if we also believe the article, the odious Andrew would have thought of Sarah as 'staff' and beneath him; but he wanted to be married and she was extremely tolerant of his foibles ... so you'd think the Unused Spares Club would accept and share that bond (of finding wives who were prepared to put up with them), not fight over it.
And interestingly, Harry has very quickly denied fighting with Uncle Andrew over M.
But Harry himself says he physically fought with William over M's suitability.
It's very curious. I remember wondering when H&M buggered off to North America whether it was something to do with putting distance between themselves and Andrew's fall from grace that was happening at round about the same time. And I naively expected H&M to speak out about it!
It's all so, so unsavoury.
