PRINCESS Diana's butler, Paul Burrell, won't be drawn on claims by Mohammed Al Fayed that his Farndon home was raided to recover incriminating tapes.
Mr Al Fayed, who believes Diana and his son Dodi were murdered by the security services, made the allegations on BBC Radio 4's Today programme.
The Harrods owner said the raid on Mr Burrell's home was to recover tapes which would have proved the animosity between Diana and the royal family.
This is despite a report by Lord Stevens which this week concluded Diana died in a car accident while not wearing her seatbelt with a drunk driver at the wheel.
But Mr Burrell, who will give evidence at the inquest into Diana's death, told The Chronicle: 'It is unwise to speculate before you know the facts.'
Mr Burrell, who was speaking from the flower shop adjoining his Farndon home, was acquitted of stealing royal possessions in the court case which followed the raid.
Lord Stevens's inquiry was triggered after Mr Burrell released a letter from Diana in which she claimed Prince Charles was planning an accident in her car.
Mr Burrell has always kept an open mind on the significance of the letter but said previously there were 'many unanswered questions'.
Speaking about the report ahead of its general publication, he said: 'I haven't read it. I shall read it with great interest. I can't really say anything because I am a witness in the inquiry led by Dame Elizabeth Butler-Sloss to be held later in the year.'
'I have always said that if called upon to defend the princess' memory I will.
' I have a moral obligation to the princess. I think anyone that has lost someone they love in their life feels like that.'
This week, tickets went on sale for the Concert for Diana, to mark the 10th anniversary her death. It will be held on July 1 at the new Wembley stadium.
Princes William and Harry, who are organising the event, wanted the concert to coincide with the princess' birthday, when she would have turned 46.
Welcoming the concert, Mr Burrell said: 'I think it's a great idea.
'I think it's a wonderful way to celebrate their mother's life and to involve the people who knew her and loved her is fantastic and I hope it raises a lot of money for the charities that were dear to her.
'Hats off to William and Harry. Despite what you read about in the Press, I have nothing but respect and admiration for the boys.
'I wish them well and I wish them happiness and good luck to them. They are fine young men.'
Sir Elton John, Duran Duran, Joss Stone, Bryan Ferry and Pharrell Williams will perform. Buckingham Palace said its phone lines were buzzing after the ticket line opened on Wednesday.
