The CDU, Germany's conservative party, is facing internal and external turmoil after its leader, Friedrich Merz, broke a long-standing taboo by collaborating with the far-right AfD to pass a migration-related proposal in the Bundestag.

This move has sparked widespread protests, with 160,000 demonstrators in Berlin alone, and criticism from prominent figures like former Chancellor Angela Merkel.

The controversy has also caused divisions within the CDU, as some members refused to support Merz's actions.

Despite the backlash, the CDU is set to discuss a "Sofortprogramm" at its Berlin party congress, focusing on economic revival and stricter migration controls.

Observers believe that while dissent exists, the party may rally behind Merz to avoid electoral setbacks.
