Prince Charles has been questioned by a former head of the Metropolitan Police over the death of his former wife, Princess Diana, it has been confirmed.
Wreckage of the car in which Diana and Dodi were travelling
The Sunday Times says Lord Stevens and the Prince of Wales met for several hours last week at Clarence House.
It reports Charles was asked about events leading up to the death of Princess Diana and her lover, Dodi Fayed, in a car crash in Paris in 1997.
Lord Stevens is studying suggestions the crash was not an accident.
Royal coroner Michael Burgess ordered the inquiry nearly two years ago amid continuing conspiracy theories over the deaths.
A Clarence House spokeswoman said: "The Prince of Wales has recently met with Lord Stevens as part of his ongoing inquiry."
Diana, 36, and Dodi, 42, were killed with chauffeur Henri Paul when their Mercedes crashed in the Pont d'Alma tunnel on 31 August, 1997.
They had been pursued by photographers after leaving the Ritz Hotel for Mr Fayed's apartment.
A two-year investigation in France blamed Mr Paul for losing control of the car because he was high on drink and prescription drugs and driving too fast.
