Thatcher came under pressure from right wing backbenchers to shut up the Prince of Wales and there was a deal done between them where he did actually shut up in the end.

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.

If you have an anecdote from one source, you file it away. If you hear it again, it may be true. Then the more times you hear it the less likely it is to be true.

While the 1980 book was being serialized in the Sunday Times, Charles attacked it through the Observer.

What was funny if you were there is that we were all immensely sophisticated people who knew exactly what she was going to say and we're chatting away, nice to see you.

Well I'm a very similar age to Prince Charles. I'm a year older than him. I was at university at the same time as him. I think in the sixties, like all the Royals, he really had very little impact on my life at all and he seemed, if anything a lot older in his attitudes.

Among other things they picked out a detail that Charles had been offered the Governorship of Hong Kong in its dying days by Thatcher in return for shutting up about the inner cities. He quite rightly in my view led the paper on this story.
