Frauke Petry, head of the Alternative fuer Deutschland (AfD) political party, speaks at the party's federal congress on April 30, 2016 in Stuttgart, Germany. The AfD, a relative newcomer to the German political landscape, has emerged from Euro-sceptic conservatism towards a more right-wing leaning appeal based in large part on opposition to Germany's generous refugees and migrants policy. Since winning seats in March elections in three German state parliaments the party has sharpened its tone, calling for a ban on minarets and claiming that Islam does not belong in Germany.
