[What follows is the text of a letter from Dr Jim Swire published in today's edition of The Scotsman.]
There is a clear message for all voters in Scotland in May. It is a bedrock of any civilised society that it offers its people a justice system that is impartial and seen to be impartial by them.
A substantial tranche of people, including some of the UK's most respected lawyers, together with a UN official observer of the Lockerbie trial (Professor Hans Koechler of Vienna), and so many others, including myself, the committee of the Justice for Megrahi (JFM) group and all the signatories to its petition, question the safety of the verdict at Zeist convicting Abdelbaset Ali Mohmed al-Megrahi of the Lockerbie bombing. Our number grows and grows.
On top of that, and more important to Scottish voters, our Scottish Criminal Case Review Commission, after three years work, decided that the verdict might be a miscarriage of justice. As things stand, we cannot be sure we got that verdict right.
I urge therefore that voters ask of any candidate for office, no matter which party he or she belongs to: "What action do you propose to take over the Lockerbie verdict if elected?" Afterwards hold him or her to the answer.
If the answer does not include a fully empowered review of the verdict, then your vote may contribute to appalling consequences for all of us in Scotland.
Our legal system may become confirmed in putting its own reputation above delivering justice impartially to the rest of us, as already seen so clearly in the McKie fingerprint case.
