Confidential interviews with British royal PRINCE CHARLES and detectives investigating the death of DIANA, PRINCESS OF WALES could soon be made public. Lawyers acting for Egyptian tycoon MOHAMED AL-FAYED - father of the DODI FAYED, who was killed alongside Diana in the August 1997 crash, will appeal for the publication of the investigation into the crash. The demand will be based on information-sharing and public-interest rules. Publication of the documents is likely to cause embarrassment to the royal family. They include transcripts of the interviews with Charles in which he is questioned whether he plotted to murder his former wife.
