Porsche is in advanced talks to sell a large stake to the Gulf state of Qatar in a deal that could turn the tables in its feud with Volkswagen. Wendelin Wiedeking, Porsche’s chief executive, is talking to the Qatar Investment Authority about selling a stake of up to 25% in Porsche’s holding company. People close to the talks said QIA was examining Porsche’s books and a deal could be announced within weeks.
