Libyan soldiers march during a military parade in Tripoli
The SAS is reportedly involved in training Libyan special forces amid suggestions it may be connected to the release of Lockerbie bomber Abdelbaset al Megrahi.
Elite UK troops have apparently been working with Colonel Gaddafi's regime for the last six months, despite Tripoli arming the IRA in the past.
Sources within the SAS are unhappy with the training arrangement, which they believe could be linked to Megrahi being freed last month, said The Daily Telegraph.
