Neo-Nazi Golden Dawn party has ignited more controversy following a demonstration on the Greek island of Crete, in which one MP unfurled the flag of the 1967-1974 military junta and another one threatened to kill anti-fascist protesters.

Spokesman and lawmaker Ilias Kasidiaris, who in June assaulted two woman MPs during a live broadcast from a television studio, was filmed arguing with police outside the Golden Dawn rally.

According to Ekathimerini website, Kasidiaris lashed out at policemen who allowed an anti-fascist demonstration to take place near the party meeting, intimating them there will be victims if the protesters were not moved away.

"Believe me, you will have dead people by tonight," the Golden Dawn spokesman can be heard telling the police in video footage of the incident.

Another neo-Nazi MP, Christos Pappas, eaved the flag of the military dictatorship that hold power in Greece from 1967 to 1974, which bears a phoenix and a soldier.

The junta, led by Colonel Papadopoulos, Colonel Makarezos and Brigadier Pattakos, imposed strict controls over the media and judicial system, suppressed any political opposition and dismantled the reforms of the last elected prime minister Georgios Papandreou.

Indeed, Golden Dawn was enivsaged by its leader Nikos Michaloliakos after his arrest in 1976 after an attack on journalists who were covering the funeral of the junta torturer Evangelos Mallios.

In prison, he met the leaders of the military junta in jail, especially the prominent general George Papadopoulos who ordered him to found the party in 1985. The organisation was listed as a political party in 1993 and won political representation in 2010 when Michaloliakos was elected to the Athens City Council.

In November, Golden Dawn MPs have been involved in a race attack against migrants in a central Athens neighbourhood after an immigrant allegedly stabbed a hairdresser in the area.

Golden Dawn extremists have been involved in a number of race-related attacks on immigrants and human rights activists over recent months.

Following the spate of attacks, Greece's parliament has decided to strip three MPs from the far-right party - Panagiotis Iliopoulos, Giorgos Germenis and Ilias Kasidiaris - of their immunity from prosecution.

Despite the controversies, Golden Dawn's popularity rose by 12 percent in the latest poll.
