A panel of judges ruled Wednesday that the leader of the neo-fascist party Golden Dawn and more than a dozen party lawmakers are among 72 people who would stand trial on charges that include participation in a criminal organization, murder and assault. The ruling followed a 15-month investigation into the party, which is widely regarded as one of Europe’s most violent far-right groups. The defendants include 18 Golden Dawn lawmakers who were elected to Greece’s Parliament in the 2012 general elections, including two who have since left the party, as well as 54 members or supporters of Golden Dawn. Golden Dawn dismissed the charges, saying the party and its supporters are victims of “persecution” and a “political frame-up.”
