LEADING Lockerbie bombing campaigner Jim Swire yesterday called for the conviction of Abdelbaset al-Megrahi to be reviewed after it was revealed that Scotland’s top law officer had met the head of the FBI.

Scotland’s Lord Advocate Frank Mulholland met FBI head James Comey to plan future joint investigations on the basis of the controversial guilty verdict.

Mr Mulholland used a speech yesterday at a memorial service at the Arlington cemetery in Washington to reaffirm his belief in the guilt of Megrahi, the only man convicted of the bombing of Pan Am flight 103 on December 21 1988.

Vowing to track down the “accomplices” of Megrahi, who died in Libya in 2012, Mr Mulholland said: “During the 26-year long inquiry not one Crown Office investigator or prosecutor has raised a concern about the evidence in this case.”

But Jim Swire, whose daughter Flora died in the bombing, expressed disappointment at Mr Mulholland’s comments and continued to press for a review.

He said: “Scotland’s own Criminal Cases Review Commission years ago found six reasons why this case should be revisited and reviewed.

“So for the Lord Advocate now to say there isn’t a shred of evidence flies in the face of what the Scottish Criminal Cases Review Commission actually told the world years ago.”

In his speech, Mr Mulholland also revealed that he had a “very useful” meeting on Friday with FBI director Mr Comey.

He pledged that Scottish prosecutors and police, along with the British government and US colleagues “will continue to pursue this investigation, with the sole aim of bringing those who acted along with al-Megrahi to justice.”

Campaigners have claimed that the case is the “worst miscarriage of justice in British legal history.”

Megrahi was jailed for life and lost his first appeal against the mass murder conviction in 2002. In 2007 the Scottish Criminal Cases Review Commission found six grounds where a miscarriage of justice may have occurred, paving the way for a second appeal.

Megrahi dropped that appeal in 2009 before being released by the Scottish government on compassionate grounds in light of his terminal prostate cancer.

He died protesting his innocence in Libya in 2012.

Earlier this year, members of his family joined with 24 British relatives of those who died in the atrocity to campaign for a third appeal against his conviction in the Scottish courts.
