Princess Diana's fatal Paris car crash was not an accident and there were "still many unanswered questions surrounding her death", according to a legal expert.
Michael Mansfield, a QC and legal legend, told the Mirror that the drivers of a mystery car and a motorbike which were also seen in the tunnel where she crashed have still never been found.
It's been 25 years since the fateful night which saw Diana killed in the horror smash along with boyfriend Dodi Fayed.
