The largest marketing company in Sweden and the national postal service, are refusing to distribute a political newspaper that contains a caricature of Muhammad, a Muslim prophet.

Posten, the postal service, stated it will not distribute the far-right Swedish Democratic SD-Kuriren, which contains a reproduction of the cartoon of Muhammad as a dog by Lars Vilks, in the nation's southern city of Svedala. Marketing company Svensk Direktreklam stated it would distribute political material only from Sweden's current parliamentary parties, The Local reported.

Distributing the newspaper would be a security risk, Posten stated, according to The Local.

“We want to protect the safety of our mail carriers. This illustration has provoked reactions that have led to death threats,” a spokesman for Posten, Per Ljungberg, told Sydsvenskan on Monday, according to The Local.

Posten made its announcement Monday, while Svensk Direktreklam announced its refusal Wednesday.

Jimmie Åkesson, Sweden's Democrat party leader, said in a statement he is furious about the refusals.

“For both Posten and its main competitor to refuse to deliver information from a particular political party is a serious threat to free expression,” he said in a statement.
