Dissident Mukhtar Ablyazov, who is accused of embezzling up to £3.64 billion from his former bank in Kazakhstan, should be extradited to Ukraine or Russia, a French court has ruled. The 50-year-old who had been in hiding since being sentenced to prison for contempt of court by an English judge 18 months ago, was arrested near the Riviera resort of Cannes last July and has been in custody since.
