New evidence and witnesses have emerged in the investigation into the death of Princess Diana in 1997, the man leading the inquiry has said.
Princess Diana and Dodi Al Fayed died on 31 August 1997
Former Met Police chief Lord Stevens made the statement in an interview at the Hay Festival in Hay-on-Wye.
However he refused to elaborate on the new material, admitting that he had revealed more than he intended to.
Lord Stevens is probing claims that the Paris car crash in which the Princess of Wales died was not an accident.
When asked about the inquiry by festival director Peter Florence, Lord Stevens said: "We've got new witnesses and new forensic evidence."
He was quizzed over whether the new witnesses were eye-witnesses, but said: "I can't tell you at this stage... you've already got under my radar."
He added: "At the end of the day we have to do a job that draws a line under this one way or another."
Lord Stevens said his team they had taken possession of the car involved in the crash, and it had been dismantled.
Lord Stevens was asked by the Royal Coroner two years ago to investigate the crash in Paris which led to the death of Princess Diana and Dodi Al Fayed in August 1997.
