In addition to Ghosn, Kelly and Mr Saikawa, six other senior Nissan officials - some still working at the firm - were found to have improperly received bonuses. Their names have not been made public. Nissan says the scheme that Mr Saikawa and the other unnamed officials participated in was not illegal, and that the issue is different from what it calls intentional misconduct by Ghosn and Kelly. And it says Mr Saikawa and the other executives will return the money involved. It is unclear whether the audit would continue, with sources saying some board members want further investigation. Then there is the unresolved business of Nissan's fractious alliance with Mitsubishi Motors and Renault. Renault holds a 43 per cent stake in the Japanese carmaker, which in turn controls 15 per cent of the French firm but has no voting rights. Sources say various changes to that structure have been proposed, but "nothing is official" yet. AFP
