London (CNN Business) Renault has replaced its chief executive for the second time in less than a year, as fallout from the ousting of Carlos Ghosn continues to destabilize the world's biggest car-making alliance.

The French automaker announced Friday that Thierry Bolloré, who had led the company since Ghosn stepped aside in November 2018, would leave his post with immediate effect. Its global partner Nissan named a new CEO earlier this week to replace Hiroto Saikawa, who resigned after admitting that he and other executives were overpaid as part of a stock plan.

Renault said in a statement that Clotilde Delbos would serve as CEO until a permanent replacement for Bollore is found.

Bolloré did not go quietly. On Thursday, as rumors of his ouster swirled, he denounced the move against him as a "coup" in an interview with French newspaper Les Echos. "The brutality and the totally unexpected character of what is happening are stupefying," he said.

Thierry Bollore speaks at a Renault press conference in September.

Nissan NSANF Renault RNLSY Bolloré is the latest in a series of top executives to exitandafter Ghosn, the former chairman of both companies, was arrested last year in Japan and later charged with financial misconduct.
