Its top official European Commission is stepping down from his role as transport policy chief following revelations that he was accepting free air travel with Qatar Airways while his team was negotiating a major aviation deal with the Gulf state.

According POLITICO report Henrik Hololei, Director-General of the Transport Department of the European Commissionfaced an internal investigation into air travel and whether there was any conflict of interest.

Hololei will leave his job as director-general of the transport department, and become political adviser without management responsibility at DG INTPA, the Commission’s department responsible for international cooperation.

A Commission spokesperson confirmed to reporters that Hololei will move into his new role on April 1.

The revelations about the free air travel sparked a firestorm of criticism, calls for an investigation and demands for a review of the rules. The Commission initially insisted that Hololei had broken no rules, but then moved to tighten the rules themselves to make sure his behavior could not be repeated in the future.
