The move would come after Nissan CEO Hiroto Saikawa resigned in September following a scandal over pay. On Tuesday, the carmaker tapped Makoto Uchida, 53, the head of its China joint venture, as CEO, to work alongside new Chief Operating Officer Ashwani Gupta. Renault had sought Saikawa's removal for his role in the alleged wrongdoing by Ghosn, and signaled support for Uchida and Gupta early on.
