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.

With less than four weeks before Germany’s federal election, Chancellor Olaf Scholz and his conservative challenger Friedrich Merz, who is leading polls, will take their contentious battle over how to crack down on illegal migration to parliament.

Hundreds of people gathered outside the headquarters of Germany's opposition Christian Democrats (CDU) in Berlin on Wednesday evening to protest against the conservative bloc pushing through a motion to tighten migration policy with the help of votes from the far right.
