The Renault-Nissan alliance drew a line under an eight-month power struggle with the French government on Friday, with a compromise deal balancing increased state influence at Renault with weakened control over its Japanese affiliate. The agreement, offering Nissan guarantees against future interference by parent Renault (RENA.PA) or its own biggest shareholder, the French state, came as a relief to Renault staff while disappointing some investors who had hoped for bigger changes to the 16-year-old carmaking alliance.
