the owner of Harrods, Mr Mohamed Al Fayed has accused US security agencies of having been involved in a huge cover-up in the investigation into the deaths of his son Dodi and Britain's Princess Diana.
In a video coinciding with the fourth anniversary of the death of the princess and Fayed's son in a Paris car crash in 1997, Mr Al Fayed said he had no doubt they died as a result of murder with racism at its core.
He has claimed repeatedly the British Royal family wanted to prevent Dodi, a Muslim, from marrying Diana, the mother of Prince William, second in line to the British throne after Diana's ex-husband, Prince Charles.
Despite several US lawsuits, Al Fayed said the CIA, the National Security Agency and the FBI had refused to hand over documents he said would prove the couple was murdered.
"Instead, they have done everything possible to delay the case and obstruct the release of documents which would show the collaboration between the United States intelligence and the British secret services,", he said in the video broadcast at a news conference in Washington.
The United States and British governments and their security agencies have repeatedly rejected claims they were involved in the deaths, calling the claims ludicrous.
A French judge closed an investigation into the crash in September 1999, concluding the accident occurred because the couple's driver from the Ritz Hotel, Henri Paul, was drunk.
