Renault, which dominates the partnership through its 43.4 percent stake in Nissan, is expected to meet within days to consider potential candidates to replace Ghosn as chief executive officer and chairman. The co-chair of a committee set up by Nissan to examine the root cause of Ghosn's alleged financial misconduct and propose corporate governance reforms said on Sunday he believed Ghosn may have had questionable ethical standards. "Having read the report on the internal investigation, my initial impression was that the head of the company may have had questionable ethical standards," committee co-chair Seiichiro Nishioka told a briefing late on Sunday after the panel held its first meeting.
