Diana, Princess of Wales, was murdered

Despite an official inquiry that found no evidence of a plot by MI6 or any other entity to murder the princess and Dodi Fayed in 1997, fevered speculation continues. The theory is that rogue elements in the British secret service decided that Diana’s relationship with Fayed was a threat to the monarchy and, therefore, to the British state. A plot was hatched in which a white Fiat Uno carrying agents was sent to blind and disorientate driver Henri Paul as he sped through the Paris underpass pursued by photographers. Later, Paul’s blood was switched with a sample of somebody who had drunk a lot of alcohol. The trouble with the theory? Not a shred of evidence exists to support it.
