Rogue trader Kerviel due back to France to face prison Rogue trader Jerome Kerviel approached the French border on Saturday as he prepares to go to prison for his role in the near-collapse of Societe Generale bank. Kerviel, who has been on a walk from Rome to Paris, has been ordered to present himself at a police station in France by Sunday at the latest with a view to beginning a three-year prison term that was confirmed when his conviction was upheld on appeal in March. Speaking on the French-Italian border on Saturday, Kerviel insisted he would keep up his campaign for 'justice'. IMAGES AND SOUNDBITES.
