BBC: An MP for the far-right party Golden Dawn has said that the arrest of its leader does not spell the end for the party.
Meanwhile Golden Dawn supporters have gathered outside police headquarters in the Greek capital, after Nikolaos Michaloliakos, three more MPs and 13 others were detained.
"This is only the beginning of their end, not ours," MP Artemios Matheopoulos told the BBC's Mark Lowen.
He also rejected the suggestion that his party had any involvement in the murder of the musician Pavlos Fyssas on 18 September.
A man held for the stabbing told police he was a Golden Dawn supporter, though the party strongly denies any responsibility. Watch BBC video » | Saturday, September 28, 2013
