I concur with Mr. Munro that "any enquiry should deal with the whole issue including the validity of the cobviction and alleged US interference in the legal process."
To accept release on compassionate grounds from the Scottish Justice Minister, Mr. al-Megrahi had to abandon his appeal against conviction - an appeal many thought him likely to win.
The Scottish government has been urged to hold a public inquiry into the Lockerbie plane bombing.
A group of campaigners who believe Abdelbaset al-Megrahi may have been the victim of a miscarriage of justice called on Friday for Holyrood ministers to launch a new investigation.
The Justice for Megrahi committee has petitioned the UN general assembly for an inquiry into the bombing of Pan Am flight 103 in 1988 which killed 270 people, as well as the trial at Camp Zeist in the Netherlands which saw the Libyan convicted of the atrocity.
The Scottish government has refused to appear before a forthcoming US Senate committee inquiry into al-Megrahi's release.
Robert Forrester has written to Scotland's first minister, Alex Salmond, and justice minister Kenny MacAskill on behalf of the Justice for Megrahi committee, claiming that "current attacks from the US and within the UK" have led to suggestions that the Scottish government might hold its own inquiry.
His letter added: "In our view, it is vital that the scope of any such inquiry ought also to encompass all aspects of the Lockerbie affair from December 1988 to the present day, including the investigation of the disaster and the Zeist trial itself.
"Clearly, it is our belief that Mr Al-Megrahi may have been a victim of a gross miscarriage of justice and, in that regard, simply to focus on the questions arising from his release is of secondary import.
"It goes without saying, therefore, that we would be fully supportive of a full, public inquiry of this type should Edinburgh wish to open one."
Forrester said the group's call for an inquiry had been backed by Dr Jim Swire, whose daughter Flora died in the Lockerbie tragedy, as well as archbishop Desmond Tutu, Private Eye editor Ian Hislop and professor Robert Black, who has been a high-profile critic of al-Megrahi's conviction.
"A step of this nature may also go some way towards restoring faith in Scotland's once justifiably envied system of criminal justice, which is now internationally derided as a result of our continuing failure to tackle the problems created and sustained by the Lockerbie affair," Forrester added.
Al-Megrahi was released from Greenock jail on 20 August last year. He had been given three months to live, but is now living with his family in the Libyan capital, Tripoli.
The controversy over his release flared up again during prime minister David Cameron's first visit to Washington this week.
The US Senate foreign relations committee want to investigate the suspicions of some that oil giant BP may have had a hand in the release.
It's not often I find myself agreeing with The Guardian, but an editorial on Saturday:
Jack Straw was yesterday considering whether to accept an invitation from the US Senate foreign relations committee to explain his role in the release of the Lockerbie bomber Abdelbaset al-Megrahi (he subsequently declined the 'kind invitation'),
The committee said the former justice minister was in "a unique position to help us to understand several questions still lingering from this decision". Maybe he is. But surely this principle works both ways: are not George Bush, Dick Cheney and Donald Rumsfeld in a similarly unique position to help the Chilcot inquiry explain a few of those lingering questions about the decision to invade Iraq?
The inquiry has already met people like Paul Bremer, the US administrator of Iraq in the aftermath of invasion, and David Kay, the head of the Iraq Survey Group, on a visit to both Washington and Boston in May. But these meetings were held in private. They were not treated as formal evidence and no transcripts were made.
Such discretion was not reciprocated by Robert Menendez, the US committee chairman, when he summoned Scotland's first minister, Alex Salmond, and its justice secretary, Kenny MacAskill, over the Megrahi release. Both men declined his invitation and denied they had been lobbied by BP. As partners in the coalition of the willing, are we not equally accountable to one another? Surely there is no one in a better position to shed light on our road to war than the people who took the real decisions in Washington. It might even explain one or two of those known unknowns.
