I don't think Charles 'chose' to marry Diana. Wasn't he told he was heir to the throne and therefore had better find a suitable virgin pdq? Don't throw things at me, I'm sure I read that somewhere! Anyway, it turned out be a bad choice for all parties concerned and no doubt there was blame on both sides, as there usually is.
I like Camilla, too. Seems a sensible lady to me with a good sense of humour. I would be in favour of her becoming queen consort, why not? She's certainly cheered Charles up. Incidentally, why does he have such a red face? Is he well, do you think?
