A LEADING QC has called for a fresh investigation into the death of Princess Diana.

Michael Mansfield insists her fatal car crash 20 years ago was not an accident.

The lawyer is suspicious because police did not react to a note Diana wrote claiming Prince Charles was planning her death in a car accident.

He said: “If you find a body at the bottom of the cliffs in Dover and the person has left a note saying, ‘I’m going to end up at the bottom of the cliffs, dead’ and, in the note, she’d indicated who she thought would be responsible for her death, I think the first port of call is to say, ‘Hmm, well there may be something in this’.”

Mr Mansfield, who represented Harrods owner Mohammed Al Fayed, makes his claims in a US documentary which resurrects a host of conspiracy theories.

It touches on claims she was killed because she was pregnant by Mr Fayed’s Muslim son Dodi.
