In the UK, an official report has concluded that the previous Labour government did all it could to help free the Lockerbie bomber before he died.
Abdel Basset al-Megrahi was release by a Scottish court on compassionate grounds.
The report said there was no overt pressure from London but behind-the-scenes contact with Libya did take place.
Prime Minister David Cameron responded in a speech to the British parliament.
He asked the House of Commons: “Was it really right for the British government to facilitate an appeal by the Libyans to the Scottish government in the case of an individual who was convicted of murdering 270 people?
Cameron continued: “I believe it was profoundly wrong and the fact that 18 months later the Lockerbie bomber is today living at liberty in Tripoli only serves to underline that.”
Libyan al-Megrahi was convicted in 2001 of blowing up Pan Am Flight 103 over the Scottish town of Lockerbie in December 1988 killing 270 people, the majority of them US citizens.
He was released in 2009 after being diagnosed with cancer and given three months to live.
The Scottish government claims commercial considerations, including lobbying by the oil giant BP, led ministers in London to change their approach.
