PC Yvonne Fletcher was shot dead in 1984 as part of an alleged plot involving a spy working for MI6, a court is expected to hear.

A High Court judge will next month be asked to decide if an original suspect was responsible for the murder.

PC Fletcher, 25, was killed by a bullet fired from the Libyan embassy in London during a protest against Libya’s then leader Colonel Muammar Gaddafi.

A source said: “We understand that at the time of the shooting one of those said to be involved was a double agent working for the British along with Libya.”

PC Fletcher’s colleague John Murray has been seeking justice since the killing.

He has launched a civil claim for damages against Saleh Ibrahim Mabrouk, a former aide to Colonel Gaddafi. While living in Reading, Berks, Mabrouk was arrested by British police in 2015 in connection with the murder.

The case was dropped in 2017, with prosecutors saying key evidence was not available to be used in court.

Mr Murray said this week: “We’re going to produce new evidence in court which would suggest criminal charges are appropriate.”

The case is listed for a three-day trial when a judge will decide if Mabrouk was part of a plot to fire at protesters.

Court papers from Mr Murray’s lawyers say: “The defendant is jointly liable with the... group who fired the shots.”

Mabrouk, who has returned to Libya, is not expected to be at the trial. He has said he is innocent, and called the civil action a “fraudulent claim which will be a waste of court time”.

He added he was not there when the PC was killed. Scotland Yard said it still aims to bring those responsible to justice.
