A coroner's jury decided on Monday thatdue to reckless speed and drinking by their driver, and by the reckless pursuit of vehicles chasing them.
Paparazzi photographers were chasing the couple in cars and on motorbikes, but Katherine Witty, a spokesman for Al Fayed, contended that two of the pursuing vehicles had not been identified.
"But whether as far as you are concerned and the general public are concerned we can do anything about that remains to be seen."
CBS News correspondent Shelia MacVicar reports that Al Fayed had said during the inquest he would accept the verdict reached by the jury, but it was clear as soon as he walked out of the courthouse that he still believed his son and the princess had been murdered.
The coroner, Lord Justice Scott Baker, had told the jury that Al Fayed and his legal team had not produced any evidence that the Secret Intelligence Service, known as MI6, was involved in the fatal car crash in Paris on Aug. 31, 1997.
Diana's sons, Princes William and Harry, endorsed the jury's verdict.
"We agree with their verdicts, and are both hugely grateful to each and every one of them for the forbearance they have shown in accepting such significant disruption to their lives over the past six months," the princes said in a statement issued Monday.
Al Fayed had claimed that MI6 agents were taking orders from Prince Philip, the husband of Queen Elizabeth II.
When he testified under oath, Al Fayed said he would accept the jury's verdict.
"When he (Al Fayed) made that declaration, it was on the assumption that the jury would be allowed to hear everything. They weren't," Cole said.
"He had no way of knowing that so many key French witnesses would refuse to come forward," Cole said, apparently referring to the lack of testimony from most of the paparazzi and from two French experts who conducted tests on the blood of the couple's driver, Henri Paul.
Paul was acting head of security at the Ritz Hotel, owned by Al Fayed.
Asked whether Al Fayed felt any responsibility for Paul's drinking on the job, Witty replied: "It was a tragedy what happened to Henri Paul. Henri Paul was an employees of the Ritz, which is not the same as saying an employee of Mohamed."
In his summation, Lord Justice Baker categorically dismissed claims of MI6 involvement.
"There is no evidence that the Duke of Edinburgh (Prince Philip) ordered Diana's execution and there is no evidence that the Secret Intelligence Service or any other government agency organized it," Baker said.
In his testimony, Al Fayed had called Philip a Nazi and accused a large number of people of being involved in a murder plot and cover up - including Henri Paul; the couple's bodyguards, who were employees of Al Fayed; former Prime Minister Tony Blair; Diana's sister and a brother-in-law; the British ambassador to Paris; the French medical service; two French toxicologists; French and British police; and the intelligence agencies of Britain, France and the United States.
