The former head of MI6 denied Wednesday that the British intelligence agency was responsible for the car accident that killed Princess Diana and her boyfriend, Dodi al Fayed, in 1997.
Sir Richard Dearlove, who was director of special operations for the agency at the time of Diana's Paris accident, testified at the inquest into the pair's death that he also believes an operation by rogue agents would have been impossible.
Fayed's father, Mohamed Al Fayed, has accused MI6 of engineering the death of his son and the princess at the behest of Prince Philip, Queen Elizabeth II's husband.
As director of special operations, Dearlove said it was his responsibility to sign off on any operation that would otherwise be illegal, such as breaking into an office or receiving a stolen document.
The operation would then have to be approved by the foreign secretary, a senior member of the government.
'Outside the function of the service' Ian Burnett, a lawyer for the coroner's inquest, asked Dearlove whether he could confirm that "no authorization was sought in respect of any activities concerning Princess Diana."
"I can absolutely confirm that," Dearlove said.
Burnett asked: "And it would plainly have been outside the functions of (the agency) to do so?"
"Had it been done, it would have been outside the function of the service," Dearlove said.
Burnett asked if it was possible for rogue elements to mount an operation outside the chain of command.
"I would have regarded that as an impossibility," Dearlove said.
Dearlove, who headed MI6 from 1999-2004, said he did not authorize any slayings, and denied a claim by former agent Richard Tomlinson about a proposed plan for assassinating Serbian President Slobodan Milosevic.
Dearlove said he believed the idea involved another target - but that it was immediately rejected at a low level.
He said the proposal was "killed stone dead."
