Princess Diana murdered by British secret service

RecordOBS-0837
CategoryUnsorted/Other
StatusDEBUNKED
SummaryThis theory alleges that Diana was assassinated by rogue elements of the British secret service, possibly because the establishment disapproved of her relationship with Dodi Al-Fayed. Proponents point to alleged inconsistencies in the official investigation. Official inquiries found no evidence of such a plot.
OriginGained traction immediately after the 1997 crash, promoted by Mohamed Al-Fayed and the Daily Express.
Claimed
  • British secret service agents killed Diana.
  • The crash was a deliberate assassination.
  • The official investigation was a cover-up.
Evidence / consensusOperation Paget and the 2008 inquest found no evidence of a conspiracy. The crash was ruled an unlawful killing by driver Henri Paul and the paparazzi, with contributing factors including lack of seatbelts and the collision with a pillar.
> OBSERVER NOTE:
The murder theory is the most persistent of the Diana claims. It fails under scrutiny; the evidence points to a tragic accident, not a plot.
