By Friederike Heine BERLIN (Reuters) -Far-right party Alternative for Germany filed a lawsuit on Monday challenging a decision last week by Germany's domestic intelligence agency to classify the party as an extremist organisation.

Germany's Alternative für Deutschland (AfD) party has been designated as right-wing extremist by the country's federal office for the protection of the constitution.

Germany has classified the AfD as a confirmed extremist party, triggering legal reviews, political fallout, and international criticism. Here’s what the move means for democracy and how global players are responding.
