Discussions about Diana and Camilla are based on what Diana claimed , where is the proof?
Diana could not have been the lamb to the slaughter some believe her to be , if there was an affair at the time of the marriage Diana would have known, her sister was in a relationship with Charles , was she to unaware of this affair.
I believe the villains of this to be Johnny Spencer and his mother in law , they must have known Diana was mentally ill but they wanted one of the sisters married to Charles . Spencer worked for queenie, the Spencer family lived at sandringham, they holidayed at balmoral . Queenie is god mother to Charles Spencer
