BERLIN (AP) — Germany’s parliament is expected to vote Friday on an opposition bill calling for tougher rules on migration that could become the first legislation to pass thanks to a far-right party — adding to a controversy about the attitude of the front-runner in Germany’s upcoming election toward the far right.

Polls show conservative leader Friedrich Merz’s Union leading ahead of the Feb. 23 election with around 30% support, while AfD is second with about 20%.

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.
