The summing-up of the inquest into the death of Diana, Princess of Wales has been halted after the discovery of potentially new evidence.
Coroner Lord Justice Scott Baker received an email from France referring to a possible sample from the body of Henri Paul.
Tests on blood and other samples from Mr Paul showed that he was three times over the French drink-drive limit when the car crashed in Paris in August 1997. Mohamed Fayed, whose son Dodi also died in the crash, maintains that the samples were faked or switched.
Lord Baker told the jury: "The cause of asking you to retire was that this morning we received an email from the French giving information in relation in very broad terms, although we have not been able to get a proper translation of it yet, to do with samples and Henri Paul.
"Whether this contains anything that is new seems very doubtful. Whether it does contain anything that is relevant also seems pretty doubtful.
"But having gone six months down the road it seems desirable that we should bottom out this problem before we go any further."
The inquest, which has been running since October 2, has heard from around 250 witnesses.
