“If boundaries are crossed there, I assure you that from the federal government’s point of view we will do everything to correct it… The Basic Law also applies in Saxony-Anhalt,” Merz said.

The anti-immigration Alternative for Germany (AfD) won the Saxony-Anhalt state election by a wide margin but fell short of an absolute majority. Nevertheless, the party may still come to power if it can garner enough support from BSW or peel off a few MPs from rival parties.

This possibility has thrust an unused and radical clause of the German constitution, federal coercion or “Bundeszwang,” to the center of a fight over how far Berlin can go if the right-wing party takes power.
