The leader of Greece's far-right Golden Dawn party has been remanded in custody on charges of running a criminal group.
Nikolaos Mihaloliakos appeared before a magistrates court and a prosecutor to respond to charges of founding and participating in a criminal organisation.
The decision to jail the party chief will be a boost for Prime Minister Antonis Samaras' efforts to clamp down on Golden Dawn after an alleged party sympathiser fatally stabbed an anti-fascism rapper last month.
Mihaloliakos was arrested on Saturday alongside other party members.
