Interesting that this one has come up again.
In order to put this whle subject into any perspective at all, it is important to consider the core facts surrounding the whole affair.
Princess Diana had suffered a severe rift with the British Royal family. She could no longer call herself her Royal Highness Princess Diana. This annoyed and humilated her.
She was the guardian of the next-but-one in line for the throne.
She set out to "Re-invent" herself and cynically exploited the media to re-position her public image as a caring, humble compassionate person, caring more about others and the deprived than herself. Yeah........
Sadly, her childhood was very strange. her birth mother left her father, Earl Spencer and ran off with an Argentinian polo player. Earl Spencer then married a strange lady called Raine (known to royal watchers and court reporters and others as Acid Raine). Raine was the daughter of the British would-be novelist Barbara Cartland and had been brought up to be a social climber par excellence.
Dodi Fayed was an habitual coke and other proscribed drug abuser, a Walter Mitti self-delusionist, who fantacised about life, dangerously. He was supported by his father Mohamed Fayed, an Egyptian poseure, with a very chequered business career, who conned the British government into allowing him to buy House of Fraser group with apparently non-existent funds. This group included Harrods store in its portfolio. Dodi's uncle was Adnan Kashogi, the multi-billionare arms dealer and original self-styled Mr Fixit, who held an effective monopoly on sourcing a wide variety of arms and other items for the Saudi royal family and government: and then fell out of favour. When Fayed refused to support his son's wastrel lifestyle, then Dodi fled into his uncle's arms. Fayed and Kashogi had fallen out years before over Fayed's divorcing Kashogi's sister and over business deals where Kashogi maintained that Fayed had ripped him off. Nice normal people!
Desperate for social acceptance and denied a British passport, repeatedly, Fayed decided -very unwisely, to buy a long lease on the house previously occupied by the Duke and Dutchess of Windsor (Edward viiith who abdicated when he married Wallace Simpson).
Fayed stupidly thought that his restoration of the Windsor's residence, in the Bois de Boulogne, in Paris would gain him acceptance into the British Court. Er, wrong! The Windsors, of course, were effectively personna non grata and the Royals family never forgave Mrs Simpson for taking away their king! Not put off, Fayed even employed the Windsor's last butler and spent oddles of cash buying up the Dutchesses effects and jewels after her death, at auction.
Fed up with this strange little man, Buckingham Palace withdrew Harrod's Royal Warrant and then cancelled Fayed's sponsorship of the Windsor Horse Trials.
When Dian met Dodi, accidently, Fayed was in seventh heaven! He encouraged them both and arranged secret trysts on his yacht, thinking, perversely that he would finally be welcomed into the bosom of the British Royal Family. He even instructed Dodi to cancel his marriage to another young lady - at the last minute!
Before the accident, Dodi had already given Diana a special ring: some say it was an engagement ring.
The Fayed Mercedes limo, in Paris was Stolen and recovered undamaged only two weeks before the fatal crash.
In a book, The Feathermen, published a few years before the accident, Sir Ranulf Fines, the polar explorer and ex SAS soldier described how such a car could be "Jarked" (SAS expression) by interposing a radio receiver to the electronic "Brain" - the ECU - and control the speed and acceleration. Also he described how further additions could subvert skid control electronics (such as rear wheel steering, ABS etc) and be used to crash a car at high sped with the driver having no control.
A strong relationship exists between the French secret service (DGSE previously SDECE) and British SIS. They exchange intel data and "Favours"; frequently and have done wince WW II.
After the accident, the French police impounded the car. They were some time releasing it.
There are a number of doubts over the authenticity of various post mortem results, in particular, the Mercedes driver.
Would the British Royal Family and more importantly, the establishment and Government want the guardian of the future king's mother, married to an unstable, drug-snorting fantacist playboy, who most of the time, obsessed with his macho image (but was actually a weak, exercise-averse wimp) carried an illegal handgun. Probably not.
Was Diana knocked off?
Make up your own mind.
