A member of Germany's central bank whose remarks about Jews and Muslims have prompted outrage sparked fresh protests Monday as he unveiled a new book amid calls for his resignation. Thilo Sarrazin, 65, whose book "Germany is doing away with itself" hit the stands earlier Monday. After several controversial comments about Muslims, Sarrazin's latest remarks about Jews resulted in fury across the political spectrum and were featured on most of the country's front pages on Monday. He told the Welt am Sonntag weekly: "All Jews share a particular gene." Chancellor Angela Merkel slammed his comments as "completely unacceptable." Sarrazin's party, the Social Democrats (SPD), decided on Monday to launch a procedure to expel him, sources told AFP. Ralf Stegner, a member of the SPD's executive, told the Tageszeitung daily: "It would be better if he left himself but I fear he will not do that."
