Britain's Princess Diana wrote a letter to former butler Mr Paul Burrell 10 months before she died in which she claimed there was a plot to tamper with the brakes of her car, it was reported today.
The princess said someone, whose name the Daily Mirrornewspaper blacked out for legal reasons, was planning "an accident".
The letter said: "This particular phase in my life is the most [the word most is underlined] dangerous.
"[Word here blacked out] is planning 'an accident' in my car, brake failure and serious head injury in order to make the path clear for Charles to marry."
The letter is certain to fuel conspiracy theorists who refuse to accept the official version of the circumstances surrounding her death.
Diana and Dodi Fayed were killed early on the morning of August 31st, 1997, when a Mercedes driven by chauffeur Henri Paul crashed in the Pont D'Alma tunnel in Paris.
A French inquiry in 1999 blamed Mr Paul, concluding he had taken a mixture of drink and drugs and was driving too fast.
In the letter, Diana went on to write about how she had been "battered, bruised and abused mentally by a system for 15 years now" but that she felt no resentment or hatred.
She said she had "cried more than anyone will ever know" but that her "inner strength" never let her down and she would "never surrender".
Mr Burrell, who has a book out, told the newspaper: "With the benefit of hindsight, the content of that letter has bothered me since her death."
He said he released the letter to the Daily Mirrorin the hope that it would lead to a British inquest and a "thorough investigation of the facts by the British authorities".
No date for an inquest has yet been announced although a similar inquiry has already taken place in France.
