Jonathan Dimbleby: Understandably, when your marriage collapsed, you form close friendships, you re-establish close friendships, of whatever character that friendship is. Were you, did you try to be, faithful and honourable to your wife when you took on the vow of marriage?
Charles, Prince of Wales: Yes, absolutely.
Dimbleby: And you were?
Charles: Yes, until it became irretrievably broken down, us both having tried.
