France's financial prosecution unit the Parquet National Financier (PNF) has broadened the scope of its investigation into claims that Ziad Takieddine, a key witness over allegations that Libya helped fund Nicolas Sarkozy's 2007 presidential campaign, was induced to change his evidence. Well-connected Paris paparazzi boss Michèle 'Mimi' Marchand is one of those under investigation over the allegations. Prosecutors now also want to look at suspicions of an extraordinary plan to bribe judges in order to free one of the late Libyan dictator Muammar Gaddafi's sons from prison in Lebanon. The idea was that, in exchange, a grateful Hannibal Gaddafi would then speak out and clear the former president's name over the 2007 election funding allegations. As Fabrice Arfi, Karl Laske and Antton Rouget report, the affair could potentially now become an international scandal.
