Colonel Gaddafi knew the Lockerbie bomber was innocent of mass murder but let him rot in prison in a political deal, his close adviser has said.
Daad Sharab, 61, was the Libyan dictator’s confidante for 22 years and visited Abdelbaset al-Megrahi three times in prison in Scotland.
The Libyan intelligence officer agreed to drop his appeal against his life sentence in return for his return to Libya on health grounds in 2009.
