The billionaire father of Princess Diana's boyfriend now blames his ex-bodyguards for the car crash that killed Diana and his son, Dodi, after insisting for months a conspiracy was behind the crash.

Mohamed Al Fayed said former bodyguards Trevor Rees-Jones and Alexander Wingfield were responsible for the crash last August "through their incompetence and unprofessional practices.""They had rules and they moved away from the rules. They let me down," Al Fayed, owner of Har-rod's department store in London and the Ritz Hotel in Paris, was quoted by Time magazine as saying in an interview published Sunday.

Al Fayed's lawyers say Rees-Jones, the sole survivor of the crash, should have insisted that Diana and Fayed wear a seat belt as he did.
