After a decade of waiting, Egyptian business tycoon Mohamed Al Fayed gets his moment in court on Monday to accuse the royal family of ordering his son, Dodi Al Fayed, and Princess Diana’s deaths.

Diana, 36, Dodi, 42, and chauffeur Henri Paul died in August 1997 when their Mercedes limousine crashed in a road tunnel as they sped away from the Ritz Hotel in Paris with paparazzi in hot pursuit.

Mohamed Al Fayed said he was there to find “what happened to my son and Princess Diana, and with God's help, I hope the truth will come out. I've been fighting for 10 years. This is the moment for me to say exactly what I feel happened to my son and Diana," he told reporters before attending the hearing, the Agence France-Presse quoted him.

Al Fayed has always claimed that a murder plot by the British royal family and the establishment was behind the couple’s death. Their driver, Henry Paul was also involved in the plot.

The owner of Harrods department store sustained that Princess Diana was pregnant with Dodi’s child and they were close to being engaged, a thing that the British royal family could not bear. They could not accept an Egyptian Muslim as stepfather to the future King of England. Al Fayed also claims that the blood samples taken from Henri Paul, the driver were “cooked.”

“Princess Diana told me personally before and during the holiday we shared in July 1997 of her fears. She told me that she knew Prince Philip and Prince Charles were trying to get rid of her,” he said in court Monday, BBC reported.

Al Fayed blamed the queen’s husband, Prince Philip, for the accident, after the release of the British police report into the crash in December 2006. The report concluded that the crash was a “tragic accident” caused by excessive speed and a drunk driver.

“I am certain, 100 percent, that (a) leading member of the royal family planned that and the whole plot been executed on his order,” he said at the time.

The British report followed a French police probe, which had also concluded it was an accident.

The coroner, Lord Justice Scott Baker, has already outlined Al Fayed’s allegations to jurors.

“It’s his belief that a decision was taken to kill both Diana and Dodi. He places Prince Philip at the heart of the conspiracy. You will have to listen carefully to the witnesses you hear to see whether there is any evidence to support this assertion,” he told the jurors, according to Reuters.

Al fayed allegations come after last Thursday, his security chief, John Macnamara told the court that Al Fayed had no evidence to implicate Prince Philip. Asked whether he believed Prince Philip was involved in a conspiracy to kill the couple, Macnamara said, “Not to my knowledge.”

The inquest on the couple’s murder started in October 2007 and has already cost the British government over two million British Pounds.
