Harrods owner Mohamed al-Fayed has called the royals "this Dracula family" and accused them of wanting to get rid of Princess Diana at the inquest into the princess' and Dodi al-Fayed's death in a Paris road accident in 1997.
Al-Fayed, who alleges that Diana and his son Dodi were killed by British security service on the orders of the royal family, said: "Princess Diana told me she had proof her life was in danger."
In an emotional appearance at the inquest, al-Fayed accused Prince Philip of being a "Nazi" and a "racist."
"You want to know his original name -- it ends with Frankenstein," al-Fayed told the court.
"It is time to send him back to Germany," he added.
He said of Diana: "She suffered for 20 years from this Dracula family."
Al-Fayed, launching a string of allegations in court against the establishment, also said of Prince Charles: "He participated and I'm sure he knew what was going to happen."
He said this was "because he would like to get on and marry his Camilla and that is what happened. They cleared the decks. They finished her. They murdered her.
"It was slaughter, not murder," he told the court.
Al-Fayed said Diana had told him that "she knew Philip and Prince Charles wanted to get rid of her."
He went on: "Diana told me on the telephone she was pregnant. I am the only person they told. They told me they were engaged and would announce their engagement on Monday morning (three days after the crash)."
Diana, 36, Dodi, 42, and driver Henri Paul, a Fayed employee, were killed when their Mercedes limousine crashed in a road tunnel as they sped away from the Ritz Hotel in Paris with paparazzi photographers in hot pursuit.
French and British police investigations both concluded the deaths were tragic accidents caused by their speeding chauffeur who was found to be drunk. Both police probes rejected al-Fayed's conspiracy theories.
But al-Fayed insisted that French and British security and intelligence services had colluded in the killing of his son and Diana, and in a subsequent cover-up.
"French intelligence helped the British intelligence to execute their murder," he said.
