In the letter to her butler Diana named who she believed was plotting to kill her. But the Mirror is not able to repeat the allegation for legal reasons so we have blanked that part of the letter out.
The document will fuel the conspiracy theories which have raged in the six years since she was killed in a Paris car crash.
But it also appears to bring fresh importance to a warning by the Queen that there were “powers at work in this country about which we have no knowledge”.
The Queen was speaking to Burrell at Buckingham Palace in a meeting that would prove crucial in the collapse of his trial for theft.
Now, plagued by that meeting and deeply troubled that there has still been no inquest in Britain into the death of Diana and her boyfriend Dodi Fayed, Burrell has come forward with the stunning new evidence.
In his new book A Royal Duty the former servant – cleared last year of stealing Diana’s possessions – claims she began to worry about her security TWO YEARS before her death and that this led her to record her fears in the document.
Before sealing the letter in an envelope marked “Paul”, the princess told him: “I’m going to date this and I want you to keep it … just in case.”
In the second paragraph of the document, written in October 1996, Diana explained in the plainest possible language that she was convinced of the plot to mastermind an accident.
Burrell describes in his book the events that led the princess to write the document at her desk in Kensington Palace.
Meanwhile, author Patricia Cornwell claimed she has unearthed material that will “lay some rumours and errors to rest” about the tragic car crash in Paris six years ago. She will rubbish stories that the Princess of Wales was pregnant with her third child. And she hopes to prove the driver of the car, Henri Paul, did not apply the brakes before the crash.
Cornwell is understood to have gained access to officials directly involved in the post-mortem on the princess’s body. Her findings will be shown in the US in an hour-long programme for ABC’s Prime Time Thursday slot on October 30.
