Germany’s Social Democratic Party says first legal steps should be taken to ban the far-right AfD party as unconstitutional. Conservative lawmakers are less keen on the idea.

A number of Germany’s conservative lawmakers have called for a cautious approach after the Social Democratic Party (SPD), the junior coalition partner, on Sunday passed a motion calling for preparations to ban the far-right Alternative for Germany (AfD) party.

The debate on whether to ban the AfD, which forms the strongest opposition force in parliament, has gained momentum after it was reclassified by Germany’s domestic intelligence agency in May as a “confirmed right-wing extremist” group — an assessment that is now under court review after a legal challenge by the party.
