Mohamed Al Fayed goes to court to try to force Queen Elizabeth and the Duke of Edinburgh to testify at the Diana inquest

Mohamed Al Fayed went to court today requesting a judicial review to force the Duke of Edinburgh to give evidence at the inquest of his son, Dodi, and of Diana, Princess of Wales.

He originally wanted Queen Elizabeth to be asked questions arising from the evidence and did not want her to appear in person. Later news reports said he had changed his mind and he wanted both Queen Elizabeth and the Duke of Edinburgh to give evidence.

Al Fayed, the owner of a London department store, has alleged that Dodi and Diana were murdered in a conspiracy initiated by the royal family, authorised by Tony Blair and executed by the security services and photographers.

However, Al Fayed's lawyers failed to force Queen Elizabeth and her husband to give evidence at the inquest. His application was rejected by three senior judges at the High Court.

Al Fayed had previously called a judicial review that ensured the inquest sits with a jury. It had been stated before it would sit without one.
