Was Princess Diana murdered?
French judges, a British police inquiry and an inquest jury all found a crash caused by a drunk, speeding driver and the photographers chasing him. No independent record supports murder, but the jury was never allowed to consider it and the white Fiat Uno has never been found.

Diana tells her lawyer, and writes in a note, that she fears a planned car “accident”
Her lawyer, Lord Mishcon, noted that she had been told efforts would be made to injure or get rid of her, for example by “a pre-prepared brake failure”. A note she left with her butler, Paul Burrell, published in 2003, says someone “is planning an ‘accident’ in my car, brake failure and serious head injury”.

Diana begins a relationship with Dodi Al Fayed
She met him on a July holiday in St Tropez as a guest of his father, Mohamed Al Fayed, owner of the Ritz in Paris and of Harrods. They spent much of August together on his father’s yacht. She had given up police protection for her private life in 1994.

The couple leave the Ritz by a back door, driven by Henri Paul, and photographers follow
Henri Paul was the hotel’s acting head of security, not a regular chauffeur. Decoy cars waited at the front. Photographers who were covering the rear exit, or who soon realised the couple had left, followed the Mercedes.

Dodi Al Fayed and Henri Paul died at the scene. Diana was taken to the Pitié-Salpêtrière Hospital and died at about 4 a.m. after emergency surgery. Her bodyguard, Trevor Rees-Jones, survived. None of them wore a seat belt.

The Mercedes brushes a white Fiat Uno, which drives away and is never found
White paint and a broken tail light show the contact. French police checked 4,668 cars before ending the search in October 1998. In 2022 the head of the French investigating unit said, “I have frustration about the Fiat Uno because I like a well-finished business.”

Tests show the driver, Henri Paul, had been drinking heavily
His samples gave readings from 1.73 g/l to 2.18 g/l, about three times the French driving limit and twice the British one. Staff served him two Ricards at the Ritz, which cannot account for that level. A prescribed drug linked to alcohol treatment was also found.

Lord Mishcon read his note to the Metropolitan Police Commissioner in September 1997. It was agreed it would be revisited only if the death looked suspicious. The coroner was told of it only after the Burrell note was published in October 2003, the police’s own report records.

A French judge rules the crash was caused by the driver, and France’s highest court upholds it
Judge Hervé Stéphan dropped manslaughter charges against the photographers and a press motorcyclist, finding that Henri Paul’s drinking, drugs and speed caused the crash. Mohamed Al Fayed appealed; the Court of Cassation upheld the dismissal in April 2002.

Britain’s Operation Paget says there was no conspiracy to murder
The Metropolitan Police inquiry, set up in 2004 at the coroner’s request to test Mohamed Al Fayed’s allegation, said “there was no conspiracy to murder any of the occupants of the car. This was a tragic accident.” It also said Diana was neither pregnant nor engaged.

A former head of MI6 confirms at the inquest that an officer once proposed killing a Balkan leader
Sir Richard Dearlove said the proposal was “killed stone dead” at a low level, denied any MI6 role in Diana’s death, and called the claim that Prince Philip directed MI6 “utterly ridiculous”. His appearance was an exception to MI6’s policy of neither confirming nor denying allegations.
- 7 Apr 2008confirmed
The inquest jury rules the deaths were an unlawful killing by grossly negligent driving
Nine of 11 jurors returned “unlawful killing, grossly negligent driving of the following vehicles and of the Mercedes”, naming the speed of both and Henri Paul’s drinking. Murder was not one of the verdicts offered: the coroner said he had not seen “a shred of evidence” for it.

“MI6 killed her”
Did British intelligence arrange the crash, as Mohamed Al Fayed alleged?
Mohamed Al Fayed pushed it “from the start”, Time reported. His lawyers set it out in a February 2003 submission to Scotland’s justice minister and a July 2003 letter urging the coroner to open the inquests.

Mohamed Al Fayed alleged that MI6, on Prince Philip’s orders, killed Diana and his son
His stated motive was that she was pregnant by Dodi and about to announce an engagement. After Paget reported he said, “I am certain, 100 percent,” that a royal had planned it with MI6’s help.

Key claim: MI6 arranged the crash that killed Diana and Dodi Al Fayed
No tier 1–2 record supports it, and the French courts, Paget and the inquest jury all found a road crash. But murder was never put to the jury, and the denials of an MI6 role come from MI6 and the Metropolitan Police, so this site cannot rate it Disproven.

Bullshit meter
- Key claim: MI6 arranged the crash that killed Diana and Dodi Al Fayed. Unverified.
- Key claim contradicted by tier 1? Not by an independent record. No tier 1–2 record supports a plot and the inquest jury found grossly negligent driving, but murder was never put to the jury and the denials of an MI6 role come from MI6 and the Metropolitan Police.
Fluff meter: possibly planted
- Can’t be traced to an original record. Absent: it traces to Al Fayed’s named allegation and to real notes Diana left.
- First appeared from new or anonymous accounts. Absent: it was made publicly by a named, known person.
- Coordinated identical wording. Not measured.
- Cited source doesn’t exist. Absent: the Mishcon and Burrell notes exist.
- Later contradicted. Not measured: the records against it come mainly from MI6 and the Metropolitan Police.
● present · ○ absent · – not measured. Lists signals only. It never accuses anyone.
Personal interest meter
- Mohamed Al Fayed, lost his son in the crash, brought the allegation, and said after the verdict that the French and British inquiries “were wrong”. T2Time, 7 Apr 2008
- MI6 and the Metropolitan Police, MI6 is the accused body and gave much of the evidence about itself; the Met investigated the allegation and had held Diana’s 1995 note for six years. T1Operation Paget report, Dec 2006pp. 97–99involved party: Metropolitan Police (a British state body investigating an allegation against the British establishment; it held Diana’s 1995 note about a car “accident” from 1997 until 2003 without telling the coroner)
“Has a documented interest” only, each one sourced. Never an implication of guilt.
Correlation meter
- Diana’s 1995 note to Lord Mishcon, is the strongest point for the MI6 theory and also the record that the Metropolitan Police held back from the coroner until 2003.

- Richard Tomlinson’s strobe-flash account, feeds both the MI6 theory and claims of a bright flash in the underpass; Paget says any flash inside the underpass came too late to cause the crash.
