Last week, the CDU broke the mainstream parties' so-called firewall of noncooperation with the far-right Alternative for Germany party, or AfD, as it relied on votes from AfD members in Germany's parliament, the Bundestag, to pass a nonbinding vote on tougher border and asylum rules.

Support for Germany’s center-right CDU/CSU alliance led by Friedrich Merz dropped in a new poll, while the Greens and two smaller far-left parties gained.

Less than three weeks before federal elections, the Forsa poll for RTL/ntv also showed support for Chancellor Olaf Scholz's Social Democrats (SPD) holding steady at 16%. The far-right Alternative for Germany (AfD) was unchanged at 20%.

Support for Germany's conservative CDU/CSU alliance has dropped to 28% ahead of elections on February 23, a poll showed on Tuesday, days after it cooperated with the far-right Alternative for Germany (AfD) to pass a motion in parliament.

The support for Germany's conservative Christian Democratic Union (CDU) and Christian Social Union (CSU) bloc has dropped by 2 percentage points to 28% within a week, according to a recent survey. This comes less than three weeks before the country's federal elections.
