An enormous amount of work's gone on since the fall of Gadafi and there's always been a question over access in Libya. It looks now that it will be possible to bring these individuals in for questioning so that is very much to be welcomed.
What the bereaved families want to know is what happened and why that plane was targeted. That has always been their overriding concern and anything that brings us closer to that is good news
A "real effort" must be made to get to the rest of those involved in murdering 270 people in the 1988 Lockerbie bombing, a stepmother of a victim has said.
Rosemary Wolfe's stepdaughter Miriam was just 20 when she was killed in the attack.
"They've [the two suspects] probably been around for years and nothing has been done so we think it's high time a real effort was made to get to the rest of the truth and to get to those involved," the American told ITV News.
Amin Khalifa Fhimah also stood trial with Megrahi, but was acquitted of any involvement.
Last year, exactly 26 years on from the atrocity, the Lord Advocate led a delegation of Scottish law officers who attended a memorial at the Arlington cemetery in Washington.
Mr Mulholland, who addressed the service, said no Crown Office investigator or prosecutor has raised a concern about the evidence in the case and he vowed to track down Megrahi's accomplices.
He has previously said the idea that Megrahi had acted alone was "risible", and said "justice has only partly been done".
Megrahi's part in the bombing has been called into question in a series of books and documentaries.
The Crown Office has not confirmed the names of the two suspects they are seeking to interview.
The ongoing investigation into the bombing remains a joint one between US and Scottish prosecutors, the Police Service of Scotland and the FBI.
The flight was on its way from London to New York when it exploded above Lockerbie, in southern Scotland, on the evening of December 21 1988, killing everyone on board and 11 people on the ground.
Megrahi was found guilty of mass murder following a trial at Camp Zeist in the Netherlands in 2001 and was jailed for life with a minimum term of 27 years behind bars. He lost his first appeal in 2002.
The following year, he applied to the Scottish Criminal Cases Review Commission (SCCRC) for a review of his conviction.
A £1.1 million investigation by the body led to a finding in June 2007 of six grounds where it believed a miscarriage of justice may have occurred.
This decision opened the door to Megrahi's second appeal against his conviction. Although a number of hearings had already been held before senior appeal judges, he dropped his appeal two days before being released from prison in August 2009.
Earlier this year, Scottish judges ruled relatives of the victims of the Lockerbie bombing should not be allowed to pursue an appeal on Megrahi's behalf.
The group of British relatives had argued they had a "legitimate interest" in trying to get his case back before a court for a full appeal.
The SCCRC had asked the Appeal Court in Edinburgh for guidance on whether members of the victims' families could take such a legal move forward.
But judges ruled in July that the law was "not designed to give relatives of victims a right to proceed in an appeal for their own or the public interest".
Reacting to the news that two Libyans have been identified as suspects in the 1988 Lockerbie bombing, Jim Swire - whose 23-year-old daughter Flora died in the atrocity - told ITV News:
Great but let’s see what the evidence is against them.
Of course we want to know who killed our family members – we still believe that no one has been held to account for Lockerbie as we think the conviction against Megrahi is unsound.
Here's a recap of the key dates in the investigation into the 1988 Lockerbie bombing plot:
Two Libyans have been identified as suspects in the ongoing investigation into the Lockerbie bombing, Scottish prosecutors have confirmed.
They believe the two individuals were involved along with Abdelbaset al-Megrahi- the only person to have been convicted of the 1988 atrocity in which 270 people were killed.
Megrahi, who was released from jail by the Scottish Government in 2009 on compassionate grounds after being diagnosed with prostate cancer, died in 2012 protesting his innocence.
Scotland's Lord Advocate Frank Mulholland QC recently met the US Attorney General, Loretta Lynch, in Washington to review progress made in the ongoing investigation.
They have now requested permission from the Libyan authorities for Scottish police and the FBI to interview the two named suspects in Tripoli.
A Crown Office spokesman said:
The Lord Advocate and the US Attorney General have recently agreed that there is a proper basis in law in Scotland and the United States to entitle Scottish and US investigators to treat two Libyans as suspects in the continuing investigation into the bombing of flight Pan Am 103 over Lockerbie.
The Lord Advocate has today, therefore, issued an International Letter of Request to the Libyan attorney general in Tripoli which identifies the two Libyans as suspects in the bombing of flight Pan Am 103.
The Lord Advocate and the US Attorney General are seeking the assistance of the Libyan judicial authorities for Scottish police officers and the FBI to interview the two named suspects in Tripoli. The two individuals are suspected of involvement, along with Abdelbaset Ali Mohmed al-Megrahi, in the bombing of flight Pan Am 103 in December 1988 and the murder of 270 people."
Campaigners who believe Abdelbaset al-Megrahi was wrongly convicted of the Lockerbie bombing are calling for his case to be re-examined.Read the full story ›
Police are appealing for information after lead and copper worth around £5,500 were stolen from a property in Lockerbie.
Approximately five tonnes of lead sheeting, and 12 square metres of copper sheeting, were taken from the roof of the Dinwoodie Lodge Country House, Johnstonebridge, Lockerbie.
The theft is thought to have happened between Saturday 4 July and Sunday 5 July.
This theft would not have been a quick one and may well have involved a number of people and vehicles.
We are appealing to anyone who may have been in the area to get in touch with us through 101 if they saw anything suspicious."
Judges have ruled that relatives of the victims of the Lockerbie bombing should not be allowed to pursue an appeal on behalf of the man convicted of the atrocity - Abdelbaset Ali Mohmed al-Megrahi.
Delivering the court's judgment, Lord Carloway said: "The Scottish criminal justice system does not at present allow victims or relatives of victims to be direct participants in criminal proceedings."
Since June last year, the SCCRC has been considering a fresh, joint application from members of Megrahi's family and the Justice for Megrahi campaign group, which includes relatives of British victims of the bombing, to review the conviction.
It was believed to be an unprecedented move - the first time in UK legal history that relatives of murdered victims have united with the relatives of a convicted deceased in such a way.
