WHEN a German newspaper in January headlined the success of populists across Europe and their absence in Germany, Frauke Petry thought: “We are here, but nobody sees us yet.” Two months later the Alternative für Deutschland (AfD) party, which calls for the euro to be broken up, started making news. These days its leaders (Ms Petry is one of a triumvirate) are on television talk-shows. Euroscepticism, or at least scepticism of the euro, has a voice. Germany’s Christian Democrats have for decades seen off all foes on the right. This is a worrying new one.
