From Lady C's book describing the meeting when Haz asked TQ for permission to marry Meg and PP told him that 'we step out with actresses, we don't marry them'.
What has not been reported is the remainder of the conversation, which came to be via two different sources, one a close friend of the Queen, another a Prince. Harry, desperately in love with Meghan and willing to do anything to keep her, discounted his grandfather's suggestion with the intensity of an addict being threatened with deprivation. He informed his grandfather that he would by marrying Meghan no matter what.
The Queen likes consensus and is always extremely well briefed as to what is going on in the world as well as within her own family, so when Philip's interdict raised the temperature, Elizabeth II intervened with the intention of lowering it. Harry did not even let her finish what she was saying. He cut her off mid-sentence with the imprecation that he was 'going to marry her and if you don't like it, you'll just have to suck it up.' The Queen had never heard the expression before, nor indeed had I until the conversation was recounted to me, but I fully identifed with her comment that 'I didn't need any explanation as to what it meant. As soon as I heard it, I knew.'
If that's how Harry treats TQ, Megz will do the same and worse. The goss from the Commonwealth Service was that she openly referred to Camilla as 'old syphilis'.
I'm with Aunty on this. Some people are just plain bad.
