Scotland’s top law officer has met the Libyan PM in secret to speed up the Lockerbie bombing probe.
Lord Advocate Frank Mulholland held talks in London with Abdurahim el-Keib last month.
It followed another summit between the two and FBI chief Robert Mueller in Tripoli in April.
The recent London meeting was not publicised at the time for security reasons.
Abdelbaset al-Megrahi, the only person convicted for the bombing, died at his home in Libya on May 20.
Last night, a Crown Office spokesman said: “The investigation into the involvement of others with Megrahi in the Lockerbie bombing remains open and the Crown is working with Dumfries and Galloway Constabulary and US authorities to pursue available lines of inquiry.
“In April, at a meeting in Tripoli, the Lord Advocate expressed his desire to the Libyan prime minister that there will be a positive response to his request for co-operation and inter-national letter of request.
“At a further meeting with the Lord Advocate in London in May, the Libyan prime minister asked for clarification on issues relating to the conduct of the proposed investigation in Libya. The Lord Advocate has undertaken to provide this.” (…)
The spokesman added: “The prime minister made it clear that he recognised the seriousness of this crime and following the clarification he would take this forward as a priority.
“As the investigation remains live, and in order to preserve its integrity, it would not be appropriate to offer further comment.”
Megrahi was freed from Greenock jail in August 2009 on compassionate grounds after being diagnosed with terminal cancer.
The intelligence officer always denied any responsibility for the bombing, the deadliest terror incident on UK soil.
