A year after the dramatic arrest of Carlos Ghosn, his wife, Carole, said the fallen auto titan should face trial in France because he won't be given a fair hearing in Tokyo.

Japan has a "hostage justice system" that considers those who are charged "guilty until proven innocent," she said in an interview with Bloomberg TV in New York. "They've put him away and now they're looking for evidence."

Carole, who is banned from seeing her husband, has also called for swifter justice following the November 2018 arrest, when Carlos Ghosn was head of a trio of global carmaking partners: Nissan Motor Co., Renault SA and Mitsubishi Motors Corp. What is likely to be the nation's biggest-ever corporate trial is set to begin as soon as April — although Carole suggested it could be postponed until after the Tokyo Olympics to avoid any harm to Japan's reputation.
