There is a similarity between Charley boy and Edward the Abdicator, both wanted to wear the mantle of nobility whilst behaving like lechers, (especially with another man's wife). Camilla like Wallis will end the eldest son's throne aspirations.
At the time of Ed the Abdicator's relationship with Wallis, a famous quote of his decision to quit was "He wanted to be the first mate of a queen, but ended up the third mate of a tramp". How very apt. A case of history repeating itself!
