The family of Abdelbasset Al Megrahi said they are “heartbroken” after their appeal against his conviction for the Lockerbie bombing was rejected.
The bombing of Pan Am flight 103, travelling from London to New York on December 21, 1988, killed 270 people in Britain’s largest terrorist atrocity.
Former Libyan intelligence officer Megrahi, who was found guilty in 2001 of mass murder and jailed for life with a minimum term of 27 years, was the only person convicted of the attack.
He died in 2012 after being released from prison on compassionate grounds while terminally ill.
His family lodged an appeal after the Scottish Criminal Cases Review Commission (SCCRC) referred the case to the High Court last March, ruling that a possible miscarriage of justice may have occurred.
However, the Court of Criminal Appeal in Scotland has now upheld the verdict of the trial court and rejected both grounds of the appeal.
The bomber’s son Ali Al-Megrahi said his family were left heartbroken by the decision.
In a statement issued by the family’s lawyer Aamer Anwar, he maintained his father’s innocence and said he was determined to fulfil the promise he made to clear his name.
The Megrahi family now intend to appeal to the UK Supreme Court and an application will be lodged within 14 days.
In a statement, the Lord Advocate James Wolffe QC said: “For 32 years the families of the 270 people murdered on the night of 21 December 1988 have shown dignity in the face of the loss they have suffered. Our thoughts are with them again today.
“The bombing of Pan Am 103 is, to this day, the deadliest terrorist attack on UK soil and the largest homicide case Scotland’s prosecutors have ever encountered in terms of scale and of complexity.
“The evidence gathered by Scottish, US and international law enforcement agencies has again been tested in the Appeal Court; and the conviction of Abdelbaset Ali Mohmed Al Megrahi stands.
“After Megrahi was convicted in 2001 my predecessor as Lord Advocate, Lord Boyd of Duncansby, confirmed to the Scottish Parliament that the investigation into the involvement of others in this terrible crime would continue. I reiterate that commitment today.
“For almost 20 years since that date Scottish police and prosecutors have continued the search for evidence. This work will continue; and there remain suspects under active investigation.”
Megrahi’s first appeal against his conviction was refused by the High Court in 2002 and was referred back five years later following an SCCRC review.
He abandoned this second appeal in 2009, shortly before his release from prison on compassionate grounds while terminally ill with cancer.
He returned to Libya and died in 2012.
