Giovanni Kessler, the director general of the European Anti-Fraud Office (OLAF), was on Friday appointed as head of the Italian Customs and Monopoly Agency.

The Italian is in his final year at the helm of the EU body, with his term ending in February 2018. It was not immediately clear when Kessler would take up his new role. The current boss of the customs agency is due to leave in mid-August, according to Italian media.

Kessler was a public prosecutor in Italian criminal courts and at the Anti-Mafia Department in Sicily from 1986 until 1998, dealing with organized crime, corruption and financial offenses.

He took over at OLAF in 2011. A year later, he oversaw the investigation that led to John Dalli, the then European health commissioner, losing his job over accusations that a businessman used his contacts with Dalli to solicit a €60 million bribe from tobacco manufacturer Swedish Match in exchange for promises to reverse an EU ban on a type of tobacco.

That investigation also ensnared Kessler, with Belgian authorities starting an investigation into allegations that he had broken the law during OLAF’s probe into Dalli — so-called Dalligate.

The European Commission lifted his immunity, opening him up to prosecution, prompting Kessler to launch legal action. Both the Belgian investigation and the case about his immunity are ongoing.
