The mayor of Bergen and the head of the port authority in Bergen are expected to be facing corruption charges, according to Norwegian news reports.

Torstein Hagen, president and CEO of Viking Cruises, however, will not face charges.

Having concluded their investigation, the Bergen police have reportedly asked the state prosecutor for corruption charges against the mayor and the head of the port authority, although it appears to be up the prosecutor to decide whether to make the charges.

The case goes back Mayor Trude Drevland accepting a paid-for-trip to the shipyard to see the Viking Star in 2015 and subsequently allegedly lobbying for the cruise line for a rule change so that the ship could be registered in Norway and fly the Norwegian flag.

The Star was eventually christened by Drevland in Bergen on May 17, 2015, the Norwegian national holiday.

The mayor also accepted an offer of a free cruise which she later turned down.
