LONDON (AFP) - Former British prime minister Tony Blair made two private trips to see Moamer Gaddafi in the run-up to the release of the Lockerbie bomber, The Sunday Telegraph newspaper revealed. Blair, who left office in June 2007, used a Libyan regime jet to visit Gaddafi in June 2008 and April 2009, the broadsheet said, citing documents discovered in Tripoli since Gaddafi was ousted from power. Blair played a major role in trying to bring Gaddafi in from the cold in exchange for giving up his nuclear weapons programme and first visited him in March 2004 in what was dubbed the "deal in the desert". A spokesman for Blair acknowledged that the visits took place and that the Libyans had raised the issue of Abdelbaset Ali Mohmet al-Megrahi but the former premier simply told them that it was a matter for the Scottish authorities. Megrahi is the only man convicted over the December 1988 bombing of Pan Am flight 103, which killed 270 people, mostly Americans, when it exploded over the Scottish town of Lockerbie. Megrahi, who has terminal cancer, was said to be only three months from death when he was freed from a Scottish jail on compassionate grounds on August 20, 2009. The Telegraph disclosure is likely to add to pressure for Blair to make public the full extent of his dealings with Gaddafi since leaving Downing Street. The Sunday paper said that the documents showed that in both 2008 and 2009, Blair negotiated to fly to Tripoli from Sierra Leone in a jet provided by Gaddafi. The Sunday Telegraph said the visits raised concerns of possible conflicts of interest between Blair's roles as a Middle East peace envoy, a business consultant and a philanthropist.
