Renault is opting to wait for the Japanese investigation, allowing Ghosn to keep his job as CEO and position as board chairman.
Japanese prosecutors arrested Ghosn on Monday, saying he and Representative Director Greg Kelly conspired to understate Ghosn's compensation at Nissan over five years starting in fiscal 2010 as being about half of the actual 10 billion yen ($88.65 million).
The scandal - the latest in a string to affect Japan Inc. - wiped millions off the stock value of all three companies but Nissan bounced back marginally in opening Tokyo trade, climbing more than half a percentage point in a falling market.
Carlos Ghosn, who was arrested this week for allegedly falsifying details of his compensation, was reportedly planning to merge Nissan and Renault before his downfall. Bollore is a long-time industry veteran who had done stints at both Michelin and Faurecia before coming to Renault. The board has requested that Nissan grant it access to the evidence of Ghosn's alleged financial misconduct "on the basis of the principles of transparence, trust and mutual respect set forth in the Alliance Charter". However, the full scope of potential allegations is unclear.
In a heated press conference, Saikawa said the actions meant Nissan would move to dismiss Ghosn, the brains behind the carmaker's alliance with Renault and Mitsubishi Motors Corp. Even as the French government-which holds a 15% stake in Renault-called for interim management to replace the besieged CEO, the leadership backed him firmly.
In a letter sent to Renault employees on Monday, Bollore expressed full support for Ghosn and pledged to preserve the alliance. On Tuesday, Economy Minister Bruno Le Maire told France Info radio that "we will not demand he be removed" from the company because "we have no proof". Saikawa did say that Nissan was committed to the Renault-Nissan-Mitsubishi Alliance, and that was echoed in Renault's statement.
The Brazilian-born businessman has been credited with turning around both Nissan and Renault before becoming the linchpin of the alliance the companies later formed.
