The Norwegian twin duo Marcus and Martinus are reporting the newspaper Dagbladet to PFU, the neighboring country's equivalent to the Media Ombudsman.
The reason is a comment that the newspaper published during Eurovision in the spring, when Marcus and Martinus competed on Sweden's behalf.
The newspaper's reviewer wrote "and now: The Qui... brothers, sorry, Marcus and Martinus".
The report has been filed by the brothers' father and manager Kjell-Erik Gunnarsen, who believes that the comparison with Nazi leader Vidkun Quisling, considered Norway's greatest traitor of all time, was a clear breach of the country's press ethics rules.
The reviewer Ralf Lofstad, who wrote the formulation in question, has previously apologized and called his language use a "humorous slip-up".
