Germany′s populist AfD party wants France excluded from common European currency | News | DW.COM | 24.04.2016

"We can have a common currency with the Netherlands, Austria, Finland or Baltic states. They have similar cultures of stability like ours," Joerg Meuthen, the co-leader of the Alternative for Germany (AfD) party, told the daily Frankfurter Allgemeine Zeitung in an interview to be published on Monday.

The AfD leader told the paper that the political culture of France and the southern European states was different from Germany's. "They don't want austerity at all," Meuthen underlined.

The AfD's deputy leader Alexander Gauland shares Meuthen's views on the exclusion of France and the southern European countries from the eurozone.

"No one wants to throw France out. But France is certainly a political problem. And for that, I have no solution," Gauland said.
