A final decision is to be made on whether the conviction of Abdelbaset al-Megrahi over the Lockerbie bombing should be referred for a fresh appeal.
A review has ruled the conviction of Abdelbaset al-Megrahi over the Lockerbie bombing which claimed 270 lives can be taken to a fresh appeal.
Megrahi died in 2012 but the appeal bid was lodged on behalf of his family and is supported by relatives of some of those killed in the 1988 disaster.
The request for a posthumous appeal against the conviction was submitted by his family almost three years ago.
The bombing of Pan Am flight 103 over the Scottish town killed 270 people.
The Scottish Criminal Case Review Commission (SCCRC) has referred the case to the High Court of Justiciary.
The request for a posthumous appeal against Megrahi's conviction was submitted almost three years ago.
It said that Megrahi's family was now entitled to seek an appeal against his conviction for the 1988 bombing.
It was lodged with the Scottish Criminal Cases Review Commission (SCCRC), which will now give its decision on whether there are grounds to refer the case to the appeal court.
This is a breaking news story and will be updated.
The SCCRC can refer a case back to the High Court if it believes a miscarriage of justice has occurred and it is in the interests of justice to do so.
The bombing of the passenger jet, travelling from London to New York, happened four days before Christmas in 1988 and killed all 259 people on board as well as 11 people on the ground in Lockerbie.
Megrahi was the only person ever convicted of the bombing.
How did we get here?
US and British investigators indicted Megrahi in 1991 but he was not handed over by the Libyans until April 1999.
May 2000 - A special trial under Scots law starts on neutral ground at Camp Zeist in the Netherlands.
31 January 2001 - Former Libyan intelligence officer Megrahi is found guilty of mass murder and jailed for life with a minimum term of 27 years.
March 2002 - Megrahi loses an appeal against his conviction.
September 2003 - The Scottish Criminal Cases Review Commission (SCCRC) is asked to investigate Megrahi's conviction.
June 2007 - The SCCRC recommends that Megrahi is granted a second appeal against his conviction.
18 August 2009 - Megrahi's move to drop his second appeal is accepted by judges at The High Court in Edinburgh.
20 August 2009 - Megrahi, who has terminal prostate cancer, is released from prison on compassionate grounds.
May 2012 - Megrahi dies at his home in Tripoli, aged 60.
July 2015 - Scottish judges rule that relatives of the Lockerbie bombing victims should not be allowed to pursue an appeal on Megrahi's behalf. Courts had previously ruled that only next of kin could proceed with a posthumous application.
July 2017 - Megrahi's family launched a new bid to appeal against his conviction.
Lawyer Aamer Anwar lodged the application with the SCCRC in July 2017 on the instruction of Megrahi's family.
He said it was also supported by Dr Jim Swire, Rev John Mosey and other relatives of Lockerbie victims after some voiced the belief that Megrahi had been the victim of a miscarriage of justice.
Dr Swire told BBC radio's Good Morning Scotland programme that it was his "sincere hope" a fresh appeal would be granted.
He added: "We have information that appears incompatible with the verdict against Megrahi."
However, other families of victims in the United States have not backed attempts to secure an appeal saying there was "nothing new" in the case and "no new facts" to justify it.
Mr Anwar said it had been a "long journey" but Megrahi's family hoped the SCCRC would decide to refer the case for a fresh appeal.
It is expected to issue its decision on Wednesday afternoon.
The Crown Office pledged in the past to work in close co-operation with US authorities if new evidence on the Lockerbie bombing becomes available.
It said prosecutors had a "number of strands of investigation" which were producing intelligence and information supportive of the original trial court's finding.
