Reuters reports Nissan Motor’s board voted on Thursday to oust Carlos Ghosn from his post as chairman following his shock arrest this week. This marks the stunning downfall of the executive once hailed as the savior of the Japanese automaker. The removal of Ghosn clouds the direction of the Renault-Nissan alliance, which he had personally shaped and pledged to consolidate with a deeper tie-up despite reservations at Nissan. Ghosn is also Renault’s chairman and chief executive.
