It is conceivable that had Lady Diana Spencer survived the suspicious car crash on August 1997 in Paris and had later borne a son to her lover Dodi al Fayed, that the future King of England would have been Muslim.
Also consider that Prince Harry, the red head, looks nothing like his older brother, the future King of England, William or Prince Charles his father. He does, however, bear a striking resemblance to Major James Hewitt, a purported one time lover of Lady Diana.
The Windors are an eccentric lot but the recent marriage of Prince William to "middleclass" Kate Middleton may forge their claim to the throne of England for generations to come.
