German political leaders called on Turkish authorities on Wednesday to take action against an Islamist newspaper which portrayed Chancellor Gerhard Schröder as a Nazi. The Anadoluda Vakit newspaper illustrated an article about Schröder on May 5 with swastikas, according to a reproduction of the page in Germany's Die Welt newspaper on Wednesday. Around 10,000 copies of Anadoluda Vakit are sold in Germany, which is home to around 2.5 million Turks. Dieter Wiefelspütz, a leading member of Schröder's Social Democratic Party (SPD), said: "This is unacceptable. I call on the Turkish authorities not to turn a blind eye if this happens again in the future." Kristina Köhler, of the opposition Christian Democratic Union (CDU), said the article was "unacceptable and shaming for Turkey." The newspaper in question is currently being investigated by prosecutors in the German city of Darmstadt for inciting racial hatred by claiming that the Holocaust was a fabrication. In February, the publishers of Anadoluda Vakit, Yeni Akit, were banned in Germany under legislation aimed at stamping out incitement to violence.
