It's all part and parcel of Harry's belief that he was her favourite. Not the Olympian or her brother who don't seem to have caused the Queen any headaches, not the heir who seems to just get on with doing his duty without a fuss with his quiet, loyal wife, not the two daughters of her favourite son, not the 2 children of Edward and her beloved Sophie. Nope, the one that takes the drugs, hellraises at school, wears the Nazi uniform, calls soldiers in HM forces racist names, marries a woman who mocks her in a documentary and throws shit at the RF while her beloved Philip is dying, and doesn't bother visiting her when she is alive. No, he is the favourite, and therefore his wife must be given equal treatment, even though she hasn't earned it, not even remotely.
