"Some of the material which is now disclosed goes to the very heart of material aspects of this case, not just issues of credibility and reliability, but beyond."

This was the verdict of Richard Keen, Dean of the Faculty of Advocates, on the recent revelations of the Scottish Criminal Cases Review Commission's Lockerbie report.

His bravura performance as Al Amin Khalifa Fhimah's defence counsel was the highlight of the trial and it is still not clear why the Law Lords convicted Abdelbaset Ali Mohmed al Megrahi on such risible witness testimony.

It was, however, disappointing that the commission ignored the "canteen culture" of the forensic evidence and the notorious insecurity of Heathrow's inter-line baggage area.

The Scottish Government should initiate a full inquiry into the conduct of the Crown Office and not hide behind Westminster as it did over the release of the SCCRC report.
