"There is no evidence that the Duke of Edinburgh ordered Diana's execution and there is no evidence that the security intelligence services or any other government agency organized it," said Lord Justice Scott Baker, summing up the findings to the inquest jury.
The six-month inquest into the death of Diana, her lover Dodi al-Fayed, and their driver Henri Paul in a car crash in Paris in August 1997 has so far cost over seven million pounds ($14 million) and has seen more than 250 witnesses give evidence.
One of the most high-profile of these has been Dodi's father Mohamed al-Fayed, who owns the luxury London store Harrods and has repeatedly alleged that his son and Diana were killed by the British establishment in order to prevent her giving birth to his son's child.
Mohamed al-Fayed has accused the husband of Queen Elizabeth II, the Duke of Edinburgh, also known as Prince Phillip, of being behind the murder.
However, Lord Justice Scott Baker did not present this theory as an option for the jury, saying that these ideas were not being considered as "there is not a shred of evidence to support them."
He also said he regretted that certain witnesses had not been entirely truthful when giving evidence, naming Princess Diana's former butler Paul Burrell as one of those who had "told lies."
Burrell, who worked for the royals for more than 20 years, has claimed that Princess Diana wrote to him saying that Prince Charles was "planning an accident in my car". He has also claimed that the Queen once warned him that, "There are powers at work in this country about which we have no knowledge."
Lord Baker presented the jury with five verdict options: negligence on the part of the paparazzi, Henri Paul, both, accidental death, or an open verdict.
