The leader of the Identity and Democracy group in the European Parliament has made a request to expel the far-right Alternative for Germany (AfD) party, according to a document seen by dpa on Thursday.
The move comes after a "string of incidents involving Mr Maximilian Krah and - by extension - the German delegation of the Group" and their impact on the group's reputation, the text of the motion reads.
Krah has come under significant public scrutiny following his comments that not all Schutzstaffel (SS) members were criminals. The SS was a major paramilitary organization under Adolf Hitler and the Nazi Party.
All nine AfD lawmakers in the group are listed for expulsion in vote taking place on Thursday.
The request to expel all AfD members from the European Parliament group was sent to top representatives of political parties in ID. The Italian party Lega has already agreed to the motion.
