The father of Princess Diana's last boyfriend Dodi al-Fayed dismissed on Thursday a new British report into her 1997 death, saying it was "garbage" if it rejects a key conspiracy claim he has long made.
Mohammed Al-Fayed, owner of Britain's Harrods department store, notably accused the author of the new report of being "blackmailed" by British intelligence services.
Fleeing paparazzi photographers, Diana, 36, her boyfriend Dodi, 42, and their chauffeur Henri Paul, 41, were killed in a car crash in a Paris underpass in the early hours of August 31, 1997.
A French investigation subsequently concluded that the driver was well over the drink-drive limit and had also been taking drugs, and that the crash was an accident.
But Mohammed Al-Fayed has long maintained that it was a conspiracy involving British intelligence agents, and notably said Paul's blood samples were switched to falsely implicate him as drunk.
Media leaks from the British report to be published later Thursday said DNA tests confirm that the samples taken from the driver just after his death were indeed his and show him to have been three times over the French limit.
Al Fayed said however that he did not trust Lord John Stevens, the former Metropolitan Police commissioner leading the inquiry.
"He have just done what the British intelligence has asked for," Fayed said. "They blackmailed him, definitely."
He added that he had hired five of Britain's leading pathologists to conduct their own investigation, the results of which ran counter to Lord Stevens' reported findings. "If he has done DNA it is garbage," he said.
Fayed told BBC radio: "How can I accept something really shocking?. I know deep in my heart that I'm the only person who knows the truth."
The news leaks said that after three years of investigation Stevens has concluded that Diana died in a traffic accident after her driver lost control of the car while drunk at the wheel.
