Carlos Ghosn, the chief executive of Renault has warned the French carmaker could disappear 'in its current form' if it is unable to be competitive at home as European car markets face a lasting slump, Reuters has reported. "Each company is tied to its home country. I do not know of any company that can be viable, that can prosper from a base that is not competitive. A company needs a natural base, Renault's natural base is France," Ghosn said. Renault plans to ask unions for a new nationwide deal on pay and conditions to avert mass layoffs, COO Carlos Tavares told the news service at the auto show. "We are not certain to have touched bottom yet," Tavares said. "We are now stuck in a situation that could last."
