The spokesman for Greece's far-right Golden Dawn party has assaulted two woman MPs in a live broadcast from a television studio by slapping one and chucking water at another.

Ilias Kasidiaris, who is already facing accusations that he was an accomplice in the mugging of a student, threw his water at Rena Dourou of Syriza (the Coalition of the Radical Left) and then slapped the Communist Party (KKE) member Liana Kanelli three times.

Police have issued an arrest warrant for him.

"When you're slapped by a beast, it's a slap on the cheek of every citizen," Kanelli said after the attack.

A spokesman for the New Democracy party said: "The people must send them [Golden Dawn] to the dustbin of history."

Kasidiaris reportedly threatened journalists and technicians offscreen also.

Golden Dawn, which obtained 7 percent of the vote and 21 seats at the parliamentary, is considered a neo-Nazi party in Greece.

Leader Nikolaos Michaloliakos has rejected claims of affiliation with Nazism, even though the party's emblem, a squared spiral, and its colours recall closely the swastika. Michaloliakos made a Hitler-style salute when he was elected in 2010 to Athens city council.
Golden Dawn has appealed to growing nationalist sentiment after harsh austerity measures demanded by the European Union and the IMF helped plunge Greece into economic turmoil.
The party's main policy is to get rid of all illegal immigrants. "No one should fear me if they are a good Greek citizen. If they are traitors - I don't know," Michaloliakos said.

Golden Dawn's anti-immigration campaign was based on the slogan "So we can rid this land of filth".

A video published on YouTube showed muscular supporters of Golden Dawn urging journalists to rise from their seats as a sign of respect for Michaloliakos when he took the stage. Those who refused were expelled from the room.

The European Jewish Congress has called on European governments to ban the extremist party, expressing concerns about Michaloliakos's remarks on Nazi concentration camps.

The party leader claimed that the camps did not use gas chambers and ovens to exterminate Jews.
