Lázár officially required the committee’s chairman Antal Rogán to call a meeting of the body next week to debate modifications to the tax.

“The Hungarian government has signaled in the course of reviews that it is prepared to weigh changes to the concept of the ad tax,” the office said in a statement. “The final decision must be made by Parliament based on the stand of the economy committee,” it added.

The statement noted that two European Union procedures had been launched against Hungary since the introduction of the tax, “as a result of the dispute between the government and the Bertelsmann group”.
