@Becles I think there was a recent article with an interview from her uncle expressing disappointment about no-one being invited. I think if there were any guests from her side we would certainly have heard about it. But I'm not going to press the point. I'd be happy to be wrong.
I'm not a Meghan hater by any means, there's a lot about her which is admirable, not least her work ethic, but I'm not taken in by the saccharin either.
The Mirror article is interesting, it puts a different spin on the rift. Perhaps what they need is professional mediation. They've both had counselling so would be open to that approach I would have thought.
