In 1986 a BBC producer approached Mohamed Al Fayed and asked him to contribute to a programme called The Uncrowned Jewels. Mr Al Fayed had recently acquired Harrods as well as a dilapidated villa in Paris that had belonged to the Duke and Duchess of Windsor. After a few discussions, it was decided that Martyn Gregory could film at the villa, and interview the Duke’s former valet, Sidney Johnson, and Mr Al Fayed himself. Unfortunately, Mr Gregory did not fulfil his side of the bargain: the hour-long documentary that was promised was chopped to half an hour, and the interviews were dropped. Mr Al Fayed would consequently have been perfectly entitled to withdraw his permission for the footage to be screened. But he did not do so.
