I watched the interview, the first one of his I have seen, and my instinctive reaction was 'he is mad.' Not a word used nowadays as so much more is understood about mental health, but it is clear he is unbalanced, has lost touch with reality, his reality, that is life within the royal family. He is obsessed with the status he has lost, through his own choice, and will not see that if he does not work for the royal family he is not entitled to the special protection he considers his birthright. And if he can damage his father, so much the better.
The vicious side to his character was very apparent; if he even knew who Charles 1 was I would think he was attempting to start a Civil War, calling in Starmer to defend him against the wicked King. No sense of timing; his father's popularity is high whereas Starmer's is at an all time low, but I doubt if he has any idea of or interest in, British politics. Several dark warnings about names and facts he knew so a new 'book' in the offing.
He claims not to have been happy when here; clearly he is not happy now, but a perfect advertisement for the techniques of brainwashing: separate from all family, friends and known connections.
But the hair-weaving is good.
