Downing Street this morning ruled out a public inquiry into the death of Princess Diana.
However, Mr Mohamed al Fayed, whose son Dodi died in a car crash with Princess Diana, insists that a public inquiry should be held after a secret letter showed Diana had predicted her own death.
Mr al-Fayed, who owns Harrods, said the letter - revealed on Monday by Diana's former butler Mr Paul Burrell - echoed what the former wife of Prince Charles had told him about fears for her life.
"The publication by Paul Burrell of a letter written to him by Diana . . . confirms the suspicions I have so often voiced . . . and which have thus far been ignored," Mr al-Fayed said in a statement this morning.
"The prime minister must now accept that the time is right for a full public inquiry. Further delay will look as though he is colluding in a cover-up and the people of this country will not tolerate that."
In the letter, which Burrell says she wrote in October 1996 and gave him for safekeeping, Diana says someone was planning to kill her in a car crash.
The person or organisation she mentioned in the letter as planning to kill her cannot be named for legal reasons.
Mr al-Fayed has repeatedly claimed that Diana and his son were murdered by British secret services because their relationship was embarrassing to the royal household.
