Of the four children of the late Queen of England, I do not think the best possible successor is Charles. There was always something clumsy about the new monarch. I believe he is well-intentioned, but I do not think he has made good choices in his life, witness Diana and Camilla. Unlike most people, I regard Diana as someone who could not be happy in marriage with anyone.
If we were to pass on Charles, that leaves the next three siblings, in order of succession, namely: Andrew, Edward, and Anne. Andrew, of course, has led too scandalous a life to be anything but a salacious footnote (Stripper Koo Stark and Jeffrey Epstein). About Edward, I know very little. He appears to be the shrinking violet of the family.
I think the most talented of the four is the current Princess Royal, Anne. When threatened with a kidnapping by a lone gunman in 1974, Princess Anne refused to cooperate, commenting only “Not bloody likely!” She was a noted equestrian who participated in the Olympics and looks decades younger than the tormented Charles.
Her peppery personality is, I feel, what the monarchy needs. But then, the actual tale of successions after the deaths of kings and queens has yielded up many weak sisters of both genders.
