Wahib Nacer

French detectives and judges investigating the financial links between former President Nicolas Sarkozy's entourage and the Libyan regime of dictator Muammar Gaddafi are making progress in relation to a key figure in the affair. He is businessman Alexandre Djouhri, currently living in London, whom French judges are trying to extradite for questioning. His right-hand man, banker Wahib Nacer, was placed under formal investigation in the affair earlier this year. Fabrice Arfi reports on the latest judicial developments that are causing concern for the Sarkozy clan.
