German Interior Minister Horst Seehofer, head of the CSU, the conservative sister party of Chancellor Angela Merkel’s CDU, has said that migration was the “mother of all political problems” in Germany and one of the principal reasons for waning support for the established parties, German media report.

“Many people now associate their social problems with the issue of migration,” he told the¬†Rheinische Post, adding that if Germany didn’t change its migration policy, major political parties would continue losing ground. He went on to link the “order of humanity” with balancing the political concerns of migrants and Germans.

Merkel, however, said she would put it differently than her interior minister.

“I say that the question of migration poses challenges,” she said in an interview with RTL television, adding¬†that there are problems and success that come with the challenges of migration.
