Golden Dawn head Nikos Mihaloliakos to outline defence 2 October 2013 Last updated at 04:40 The leader of Greece's embattled far-right Golden Dawn party is to appear in court on Wednesday to outline his defence against charges of organising a criminal group. Nikos Mihaloliakos was one of six MPs arrested over the weekend in an unprecedented police operation against the party. It came amid intense public anger over the murder of an anti-racist musician. Four MPs have already made preliminary court appearances. In all, 22 people have been detained following the 18 September murder of Pavlos Fyssas. Chanting supporters Mr Mihaloliakos faces charges including murder, assault and money-laundering. According to Greek law, he will set out a preliminary defence argument when he appears before an investigative judge on Wednesday. The judge will then decide - on the basis of the charges and the defence statement - whether to grant bail or remand Mr Mihaloliakos in custody pending his full trial, which the authorities are keen to conclude swiftly. The four MPs - Ilias Panagiotaros, party spokesman Ilias Kasidiaris, Yannis Lagos and Nikos Michos - appeared in court on Tuesday. Mr Mihaloliakos's deputy, Christos Pappas, is set to appear in the coming days.

During Tuesday's court appearances, there was a heavy presence of riot police - a reminder that despite falling popularity in the opinion polls, the party still commands significant support, our correspondent says. Supporters outside court chanted slogans, including "You are heroes!" Details from witness testimony have been emerging about the way in which the party operated.

Golden Dawn officially denies being a neo-Nazi movement, despite its swastika-like insignia.
