German conservative leader Friedrich Merz is set to take his hard-line immigration push to the next level despite a growing backlash over his move this week to force a resolution through parliament with backing from the far right.

Germany's opposition conservatives won parliamentary approval on Wednesday for a proposal to drastically restrict migration with the help of votes from the Alternative for Germany (AfD), breaking a taboo on cooperation with the far-right.

A non-binding motion calling for tougher border and asylum rules passed with support from the far-right Alternative for Germany (AfD). During the stormy session, politicians of various parties hurled criticism and blame at each other.
