His comments will stoke the controversy that has surrounded the circumstances surrounding Diana's death and will also be seized on by people who apparently believe the Princess's death was deliberate. In an interview with the Mirror, Mr Fayed said he had decided to speak because of all the "rubbish" written over the past week about the crash.
"I believe in my heart 99.9 per cent that it was not an accident. That car didn't accidentally crash. "There was a conspiracy," he said. "I will not rest until I have established exactly what happened. I have great confidence in the investigators in Paris and I believe that we will find the truth."
"Everyone wants to blame the driver. It suits everyone to say it was just a drunken driver," he tells the paper.
"I will find the person who caused this accident. I will not sleep. I will not rest until I have done so. I believe there were people who did not want Dodi and Diana to be together."
He also said that if more had been done to help Diana and Dodi, they could still be alive.
He also claimed that Trevor Rees-Jones, Diana's bodyguard who survived, heard the Princess speak after the crash. "He is beginning to remember more and more. She tried to talk," he said. "Trevor remembers her saying "Where is Dodi, where is Dodi?"
He also said that a nurse at the hospital where Diana was taken after the crash claimed the Princess spoke to her. He said the nurse told him Diana said: "I would like all my possessions in Dodi's apartment to be given to Sarah including my jewellery and my personal clothes and please tell her to take care of my boys."
The Paris hospital has consistently denied that Diana uttered any last words.
Mr Al Fayed's comments follow articles and "investigations" in several newspapers about the crash in August in which the Princess, Dodi Fayed, and their driver, Henri Paul, died.
A spokeswoman for the Princess's office said last night: "We have no comment on [the article] but this continued speculation is both unhelpful and upsetting to the family."Reuse content
