Nissan wants Britain to pledge compensation for any tax barriers resulting from its decision to leave the European Union or the automaker could scrap a potential new investment in the country¡¯s biggest car plant, its CEO said Thursday.

Carlos Ghosn¡¯s remarks indicate growing concern among global carmakers that Britain could be heading toward a hard exit from the EU, which would leave them paying tariffs to export U.K.-assembled cars to EU markets.

Nissan, which builds around a third of Britain¡¯s total car output at its plant in Sunderland, northeast England, is due to decide early next year on where to build its next Qashqai sport utility vehicle.
