Free speech is guaranteed, though promoting racism or incitement to racism is forbidden. Journalists may be imprisoned for "insulting" the king, the consort, the heir apparent, or an official present in the Netherlands of a friendly government. No recent cases have been reported, but journalists self-censor to avoid criticism of the royal family. Radio and television, under the supervision and regulation of the state, operate freely and provide diverse views. All Dutch newspapers cooperate in the administration of the independent Netherlands News Agency.
