Britain woke to the news that the people's princess had been killed in a high speed car accident in Paris.
Early reports claimed that Diana had survived the crash which also claimed the lives of Dodi Al Fayed and the vehicle's driver, Henri Paul.
In the early hours it was announced that Diana had died after lengthy attempts to resuscitate her at a nearby hospital.
The accident happened after the princess left the Ritz Hotel in the French capital with her companion, Dodi Fayed, son of Harrods owner Mohammed Al Fayed.
The princess' car was being pursued at high speed by photographers on motorbikes when it hit the 13th pillar of the Ponte de l'Alma road tunnel.
Blood analysis at the time showed that Paul, the driver of the black Mercedes was illegally intoxicated. In a statement Buckingham Palace said the Queen and the Prince of Wales were "deeply shocked and distressed".
