BERLIN (AP) — Chancellor Olaf Scholz's main challenger in Germany's upcoming election plans to put proposals for a tougher migration policy to parliament on Wednesday, a maneuver aimed at piling pressure on the governing parties that has brought accusations that he's breaking commitments to shun the far right.

Chancellor Olaf Scholz’s main challenger in Germany’s upcoming election plans to put proposals for a tougher migration policy to parliament

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.

Germany's opposition leader vowed Thursday to bar people from entering the country without proper papers and to step up deportations if he is elected chancellor next month, as a knife attack by a rejected asylum-seeker spilled over into an election campaign in which he is the front-runner.

German Chancellor Olaf Scholz has described a vote in parliament on a motion to tighten migration policy passed with support from the far-right Alternative for Germany (AfD) a "bad sign" for the country.
