VW ups offer for Porsche stake

German carmaker Volkswagen is set to up its offer for a 49.9 per cent stake in luxury rival Porsche to more than €4bn (£3.8bn), it emerged yesterday, as Porsche’s controlling families Porsche and Piech met for talks. They will also discuss an offer from Qatar for Porsche and VW, which the Persian Gulf state has said it wants to invest in.
