Thierry Bolloré has been appointed as the new chief executive of French carmaker Renault, while Michelin's Jean-Dominique Senard had been appointed chairman.
The company’s former chairman and CEO, Carlos Ghosn resigned from the French carmaker this week, as he remains imprisoned in Japan, under charges of financial conduct at Nissan.
Mr Ghosn, who oversaw Nissan's recovery after Renault took a stake in the company in 1999, starting a new global alliance between the two carmakers, was sacked by Nissan shortly after his arrest on 19th November.
He faces three charges of financial misconduct, including understating his income and aggravated breach of trust.
Nissan's chief executive Hiroto Saikawa welcomed the news as the two carmakers pledged to continue their alliance.
"In the big picture, this is a big milestone that we are reaching. We are starting a new chapter. So I welcome this new leadership of Renault," Mr Saikawa said.
The Nissan-Renault alliance, which was joined by Mitsubishi in 2016, sold 10.6 million vehicles in 2017 and employs 470,000 people around the world.
