It's a good idea, if Charles was an absolute monarch, but he isn't, he's a constitutional monarch. He can't even get his brother out of Royal Lodge because he has a legal contract. There is no way Charles can get Andrew to face up to the consequences of his actions beyond what he has already done.
In the wider context though, why is it only Andrew's name we read in connection with Epstein? Why doesn't the lawyer go after some of the other high profile names? Is it because they would fight back?
Andrew is an entitled, arrogant, man who in all probability slept with a 17 year old when he was in his 40s which is disgusting and he should be ostracised from public life, as he has been. I do wonder though what is being hidden in the shadows by men with real power when the light is shone so brightly on Andrew. Those men are still getting away with it.
