For a time during the 1980s the Royal Family were not just the most influential family in Britain but probably in Europe and Prince Charles specifically was very much like a defacto Cabinet member and what he said actually had impact on public policy...
He's a TV producer, a theatrical impresario, and he wants to be treated as Mr. Windsor but when the going gets rough he wants to be treated like a member of the Royal Family.
I would argue that television and particularly the BBC were instrumental in puffing up the Royal Family to a level where they were inflated out of all, all proportion to their relevance on the national scene.
Stories about Diana's fashions, about possible rows between Charles and Diana, these were meat and drink.
They defined what was private and what was public and they would move it whenever they wished.
