The failure to track down a white Fiat Uno said to have been in the tunnel on the night Princess Diana was killed is a continuing frustration, investigators say.
They told a Channel 4 documentary, Investigating Diana: Death In Paris, that the unknown driver could have helped to try to explain the movements of the black Mercedes that Diana was travelling in.
Martine Monteil, head of the French Brigade Criminelle, said: “I have frustration about the Fiat Uno. For sure, it’s out there. Unfortunately, we don’t have it.”
