Opposition Democratic Coalition MEPs have asked the European anti-fraud office (OLAF) to launch a probe into the activities of Hungary’s national tax office (NAV). DK spokesman Zsolt Gréczy said that Csaba Molnár and Péter Niedermüller had addressed a letter to Vera Jourova, European commissioner for justice, and the head of OLAF in connection with corruption, suspicion of a cover-up of VAT fraud and the case of the tax office’s chief Ildikó Vida, who has been banned from entering the United States.
