What was Princess Diana's cause of death?

During the early hours of 31 August 1997, Diana, Princess of Wales, died from injuries sustained earlier that night in a car crash in the Pont de l'Alma tunnel in Paris, France. Diana's partner, Dodi Fayed, and the driver of the Mercedes-Benz W140, Henri Paul, also died upon impact. Diana's bodyguard, Trevor Rees-Jones, was seriously injured, but was the only survivor of the crash.

Some media claimed that the erratic behaviour of the paparazzi chasing the car, as reported by the BBC, caused the crash. In 1999, a French investigation found that Paul lost control of the vehicle at high speed while intoxicated by alcohol and under the effects of prescription drugs, and concluded that he was solely responsible for the crash.

Diana was 36 years old when she died. Her death sparked an outpouring of public grief in the United Kingdom and worldwide, and her televised funeral was watched by an estimated 2.5 billion people.
