Murder or Accident
Unlike many conspiracy theories, though, this one had a billionaire promoting it: Mohamed Al-Fayed, the father of Dodi Al-Fayed, who was killed along with Diana. Al-Fayed claims that the accident was in fact an assassination by British intelligence agencies, at the request of the Royal Family.
Al-Fayed's claims were examined and dismissed as baseless by a 2006 inquiry; the following year, at Diana's inquest, the coroner stated that "The conspiracy theory advanced by Mohamed Al Fayed has been minutely examined and shown to be without any substance." On April 7, 2008, the coroner's jury concluded that Diana and Al-Fayed were unlawfully killed due to negligence by their drunken chauffeur and pursuing paparazzi, The New York Times reported.
The conspiracy theory was also believed by Prince Harry, who said in January, 2023, that he believed she could still be alive for "many years" after the crash. He told Anderson Cooper on "60 Minutes" that he thought she may have faked her own death and they would be reunited at some point.
