Nissan Motor Co. is unlikely to select a new chairman at a board meeting next week to fill the post of ousted head Carlos Ghosn, who was arrested last month over his alleged financial misconduct, sources familiar with the matter have said.

The Japanese automaker initially planned to decide the successor at the Monday meeting, possibly tapping CEO Hiroto Saikawa as interim chairman. But it will forgo the decision, apparently taking into consideration that its alliance partner Renault SA has not taken any action against Ghosn, who remains as chairman and CEO of the company.

The sources said Friday that Nissan is looking to first focus on enhancing corporate governance amid criticism that Ghosn, who is credited with rescuing Nissan from near-bankruptcy in the 1990s, was allowed to have extensive powers and make decisions at his own discretion over company management.
