I personally felt that his ad hominen attacks on British architects were not the sort of thing a Prince of Wales should be doing because, apart from anything else, they put various people out of business.
When the young Princesses Elizabeth and Margaret were growing up, that was at it's height and the War cemented that with photographs of the Royal Family having breakfast together and so on, by pinning their reputation so firmly on that particular issue.
The Princess's so-called 'time and space speech' at the end of '93 about a year after the formal separation, looking back on it it's called her retirement from public life but we've seen in fact it's nothing of the kind.
Charles was very intent to use his years as Prince of Wales to make his mark while he still had freedom of maneuver that he wouldn't have as King. The first subject he really went for was architecture. It made an impact.
I decided he'd changed so much that a whole new book was required and that book actually I can say so was the first to say that the marriage was in trouble and the Prince didn't like at all and my book was being serialized in the Sunday Times over five weeks.
