Mohamed Al Fayed is taking legal action in France
The Harrods boss claims Lord Condon deliberately withheld evidence from the French inquiry into the 1997 deaths of the Princess of Wales and his son Dodi.
He believes that Diana's claims of a conspiracy to kill her, made two years before her death, should have formed part of Lord Condon's evidence.
But Lord Condon said he co-operated fully with the investigation in Paris.
Another former senior police officer, Sir David Veness, has also been accused.
In 1995, Diana told her lawyers she believed there was a conspiracy to "put aside" her and Camilla Parker Bowles either in an accident or by other means.
Three weeks after she died, Lord Condon, then the Met Police Commissioner, learned about the Princess's concerns.
His view then was that the facts showed Diana had died in a tragic accident, but he would review the evidence if her death was ever regarded as suspicious.
Mr Al Fayed alleges Lord Condon should never have concealed potentially relevant information from the French.
His son, Dodi, also died in the road crash in Paris in August 1997.
