The former SAS sniper, who was at the centre of the Princess Diana murder probe, has come under attack, as top brass try to silence him, according to reports.
Former sergeant "Soldier N" fled to Thailand after declaring Diana's fatal car crash had been caused by members of his elite regiment.
Security chiefs are now attempting to play down his sensational claims, which match those made in a book by another former SAS man, the daily Star reported.
Soldier N told his wife that a team from the Who Dares Wins regiment caused Diana's fatal 1997 crash by shining a light into her driver's eyes.
The Royal Military Police handed his evidence to Scotland Yard after it emerged earlier this year.
But before detectives could speak to Soldier N, he disappeared to south-east Asia.
In an apparent bid to undermine him, it has now been claimed he could have got the story from a book published shortly after Diana's death.
