German Chancellor Angela Merkel has received a strong vote of support from a top European politician for her leadership on the migration crisis.

Merkel's open-door stance to asylum-seekers has been under increasing pressure at home, including from within her own conservative bloc, but European Commission President Jean-Claude Juncker says "Angela Merkel will outlast all of her current critics in office."

Juncker told Bild newspaper Wednesday "chancellors have always been recognized for staying the course in turbulent times. I'm thinking above all of the visionary reunification policies of Helmut Kohl — history has showed he was right and it will also show Angela Merkel is right."

Juncker says he hopes other leaders at an EU summit take her stance that the refugee crisis can only be solved by working together.
