Nissan itself faces charges of allegedly submitting financial documents that understated Ghosn's pay, and Renault is now reportedly seeking more sway on the Japanese firm's board. The Wall Street Journal reported on Sunday that Renault urged Nissan in a letter to hold a shareholder meeting to discuss Renault's representation on the firm's nine-member board and within its top management. It warned that Nissan's indictment "creates significant risks to Renault, as Nissan's largest shareholder, and to the stability of our industrial alliance", the Journal reported. A source with knowledge of the issue confirmed Nissan had received the letter and was planning an extraordinary shareholders' meeting, though regulations on calling such a meeting make it unlikely to happen before February. Renault's letter is the latest sign of the tensions in the alliance that groups the firm with Nissan and Mitsubishi Motors - a partnership that Ghosn forged and was often credited with holding together.
