Germany must deport 350,000 migrants as soon as possible, a senior figure in German Chancellor Angela Merkel’s sister party has said.

Markus Soeder, the Bavarian finance minister in the Christian Social Union (CSU), which is partnered with Merkel’s Christian Democratic Union (CDU), used an interview with the Die Welt newspaper to call for a more coordinated plan to process asylum applications and deport failed applicants.

“We need… an agreement between federal and state governments—350,000 people should be deported,” he said. This must be done consistently and quickly.”
