An investigation in Britain has found the former Labour Government did all it could to facilitate the release of the Lockerbie bomber from jail in 2009.
But it says ministers did not put pressure on the authorities in Scotland, where the Libyan, Abdelbaset Ali al-Megrahi, was serving his sentence over the deaths of 270 people in the bombing of a passenger plane.
The decision to grant his release on compassionate grounds because of his terminal prostate cancer has been heavily criticised.
Doctors had suggested Megrahi would die within three months, but he is still alive.
The investigation was carried out by Britain's most senior civil servant, Sir Gus O'Donnell.
Current British Prime Minister David Cameron says there was no conspiracy involving the previous Government but he believes Mr al-Megrahi should not have been released.
