Lot's of rumours swirl around his past - no doubt.
Three of his four sisters, for instance - marrid Nazi's. He is alleged to have dug his heels in with the Queen adopting his surname, not hers, for their children (Mountbatten Vs Windsor).
All in all, he's done the Queen proud - standing by her for all this time, through thick and thin.
Wouldn't want to be on the receiving end of his razor sharp wit though!
