The Bremen government coalition made up of the Greens, SPD and Left wants to push ahead with possible ban proceedings against the AfD. Only the Federal Constitutional Court can decide on a ban - after an application from the Bundestag, Bundesrat or Federal Government.

The AfD is a real danger to society, democracy and its institutions, says Greens parliamentary group leader Sofia Leonidakis. "The instruments of the constitution are not there for the gallery, but to protect it when necessary. From our point of view, the time has come for this," she says.
