A document published by Mediapart detailing how the Gaddafi regime in Libya agreed to secretly fund Nicolas Sarkozy’s 2007 presidential election campaign is genuine, according to the conclusions of an expert analysis ordered by a French judge. The evaluation, involving highly sophisticated technology, was carried out as part of a judicial investigation into a complaint lodged against Mediapart by the former president for for ‘forgery and use of forgery’. The emphatic conclusion follows on a graphologists’s report that found the signature on the document was indeed that of Muammar Gaddafi’s spy chief, Moussa Koussa. Fabrice Arfi reports.
