The father of Diana’s driver Henri Paul is claiming UK police told him she was murdered.
Jean, 85, said: “Inside Scotland Yard, some believed there was a secret plot to kill Diana.”
In an emotional interview at his home in Lorient, Brittany, Jean – who has studied the evidence and seen classified information surrounding the tragedy over the past 20 years – said: “Diana was killed and my son was killed. I believe they were both murdered. My son was simply collateral damage of a plot to kill Diana and they killed him as well.
“I am 100% sure he was not involved in this plot. He was too honourable and too honest. The English police came here to visit me and sat exactly where you are sitting now.
“Even inside Scotland Yard there are two sides. One believes there was a secret plot to kill Diana, the other believes it was a genuine accident.
“Even today there are too many classified secrets with this incident.
“I have no real hope to know what really happened. Perhaps it will be known in 30 or 50 years. But I would really like to know before I die. But I don’t think it will happen.”
And the former council worker angrily hit back at claims Henri, 41, was boozed up at the time of the crash in August 1997. He added: “He was not an alcoholic. He was not a drug addict. That’s just lies.”
He claimed his son’s blood sample could have been swapped or tampered with to make it appear he had drink in his system.
Jean, who saw Henri’s body at a hospital, said: “On that day there were over 20 autopsies that took place and it was easy for the authorities to switch blood samples to show alcohol was present in the sample they said was Henri’s.
“That is what I believe happened.”
The jury at Diana’s inquest, which heard from 250 witnesses and lasted three months found the 36-year-old and Dodi, 42, had been unlawfully killed and the deaths were the result of “gross negligence” on the part of Henri and paparazzi who were following their Mercedes on motorbikes.
And in 2013, the Met dismissed reports claiming SAS troops were behind the couple’s death, insisting there was “no credible evidence” of secret service involvement.
There were also allegations a mystery white Fiat Uno could have collided with Diana and Dodi’s car.
But frail Jean said: “It took them over an hour to get Princess Diana to hospital and that is when they made arrangements to make up the story about the Fiat Uno, the white car. It was a diversion and a decoy.”
“This was just one of the many things that do not add up. For example I still cannot believe a street cleaning vehicle was going through the tunnel cleaning up just a few hours after the accident. That is shocking.”
Dodi’s dad Mohamed al Fayed also believes his son and Diana were murdered by an Establishment appalled at the idea of having a Muslim wed a royal.
A friend of the Harrods owner reportedly said last week: “Mohamed remains confident that information will emerge confirming his belief that Dodi and Diana were deliberately killed by the security services.
“He always says, ‘My son was slaughtered’, and he believes that was because the Establishment would not allow a Muslim to be married to the woman who would be the mother of the future king.”
Diana’s former lover James Hewitt told an inquiry into her death that he was “warned off” and received phone calls telling him to end their liaison, which lasted from 1989 to 1990.
But he denied reports he had been warned by MI5 that if he did not stop seeing her he would die in a car crash.
It was meant to be the happiest time of her life, but shocking new claims reveal Princess Diana was prescribed Valium on her honeymoon after becoming increasingly mentally unstable.
Aged just 19 when she met Prince Charles, the dazzling blonde thought she had hit the jackpot until it emerged her dazzling Prince Charming was in love with another woman.
Diana’s first lover after her marriage to Prince Charles, bodyguard Barry Mannakee, was killed in a 1987 road smash. Some of his family believe the secret services were behind the death, but that has never been proven.
His brother-in-law Richard Emmins reportedly claimed: “First, he had this accident, then Diana dies in a Paris car crash…however getting to the truth will probably be impossible. We are up against the Establishment. They only let you know as much as they want you to know.” On Saturday the Mirror told how chauffeur Karim Kazi claimed the Mercedes was a “death-trap” and should never have been allowed on the road after it was written off and parts stolen.
And Jean added his thoughts to the state of the Mercedes the princess and Dodi died in. He said: “The truth is the car was old and it was dangerous and it should not have been driven.
“The brakes were dangerous. They discovered 6% water in the brake fluid. How did that happen?”
“There was a piece of metal found at the scene, but nobody knows what it was. There are too many unanswered questions. But I do know my son is dead.” Jean still lives in the in the house where he and wife Giselle raised their five sons.
Former teacher Giselle, 87, was traumatised by Henri’s death and is now very ill living in a care home.
Jean told of the terrible moment they were informed their son had died.
He said: “I was here at home and the phone went in the middle of the night.
“It was about 3am, it was a colleague of Henri. He told me Henri was dead.
“The Chief of French Police should have called me to tell me the news but he didn’t, but did apologise later. It didn’t matter really as it didn’t change anything. Henri was dead.”
But it was not the only tragedy to hit the family – as Jean and Giselle have outlived all but one of their five sons.
He added: “Henri was still alive and attended the funeral of his brother Pascal who died of cancer. Then Henri died in Paris, then Jean-Luc who died from a heart attack. Then the youngest Sylvan died. He died suddenly. It was an aneurysm he was only 51.”
Henri was buried but then exhumed and cremated. His ashes were placed with those of his brothers.
Jean paid tribute to his chauffeur son and said it was time the world knew “the real Henri Paul”. He said: “Henri was a loyal and generous man.
