Greeks March Against Far-Right Party Golden Dawn
Demonstrators shouted “Neo-Nazis out” in rallies called by left-wing and anti-racism groups in Athens.
On Thursday, Ilias Kasidiaris, a Golden Dawn MP, was filmed hitting a left-wing politician during a chatshow.
The rally comes nine days before elections which could result in a Greek exit from the Eurozone.
In polls a month ago, Golden Dawn surprised many by winning 21 seats in Greece’s 300-seat parliament.
A second election is taking place as no party was able to forge a coalition.
Prosecutors said an arrest warrant has been issued for Mr Kasidiaris, whose whereabouts remain unknown after he fled the television studio on Thursday.
The assault took place during a live debate on a daily morning political show on the private Antenna television.
