From what I can gather... One of the things that came out of the Paul Burrell trial was that he had information about an alleged rape of one of the male servants by one of Prince Charles's butlers. No charges were ever brought against the butler even though the police were investigating it. I haven't read any details about it in the papers but in all honesty, I couldn't really give a toss about what Burrell has to say. It's one thing to say that it's royal protocol not to divulge secrets - And another to sell your story for 100k.
Of course, any sort of sordid scandal that is some way affiliated with the Royals is bad. And you can imagine how the press are having a field day wih such lurid details. However, it'll blow over soon and the press will find something else to bitch and moan about..
