According to the book, he "unwittingly assisted in his own murder," the Daily Star reported.
Author Alan Power, who has penned 'The Princess Diana Conspiracy', reckons Paul had been secretly working with MI6 agents on another case.
But behind the chauffeur's back, MI6 had colluded with an SAS hit squad to bump off the princess on August 31, 1997.
The British spooks ordered "stooge" Paul to drive the car to the Pont d'Alma tunnel in Paris, where the vehicle crashed, so their plan could be carried out, the book says.
Power said that Henri didn't know he was taking Diana, Dodi, and himself to their graves at the hands of vicious criminals.
The chauffeur has always been blamed for the tragedy because post-mortem results claimed to show he was three times over the drink drive limit and had taken prescription drugs.
But Power claims that Paul was not drunk that night, saying he had only had two drinks.
