CIA memos reveal doubts over 'key' Lockerbie witness

Mr Giaka eventually returned to Tripoli in 1990 after the CIA money dried up. But the agency kept in touch with him and finally persuaded him in 1991 to come to America. Nine years later, Majid Giaka arrived at the Lockerbie bombing trial in the Netherlands. He described how he had seen Megrahi and his co-accused, Khalifa Fhimah, at Luqa airport before the bombing with a large brown suitcase. But the CIA cables confirm that nearly two years before, Mr Giaka didn't remember anything.

At the Lockerbie trial, the four judges described some of his evidence as "at best grossly exaggerated and at worst simply untrue" and concluded he was "largely motivated by financial considerations".
