Diana inquest coroner demands Channel 4 tunnel footage

The coroner in the inquest into the death of Princess Diana has urged British broadcaster Channel 4 to hand over all footage acquired for their programme 'Diana: Witness in the Tunnel' - because it could provide vital new evidence about the royal's demise.

The inquest aims to establish whether Diana and her boyfriend Dodi Fayed, who were killed the French car crash on 31 August 1997, were simply the victims of a tragic accident, or if they were the targets of an assassination plot headed by the British royal family - as claimed by Fayed's father, tycoon Mohamed Al Fayed.
