Two jailed Greek lawmakers granted special prison leave have appeared in Parliament to defend themselves against charges linked to the Nazi-inspired Golden Dawn party.

Golden Dawn lawmaker Georgios Germenis, and Efstathios Boukouras — whom the party expelled this year — both deny illegal firearms or ammunition possession.

Parliament will vote later Wednesday on whether to lift their immunity from prosecution on the charges.

Authorities launched a sweeping investigation into Golden Dawn after last year's murder of a left-wing musician, allegedly by a party supporter.

Party leader Nikos Michaloliakos, Germenis, Boukouras and another three of the 18 lawmakers elected on the Golden Dawn ticket are in jail pending trial for allegedly running a criminal organization, and immunity has already been lifted on those charges. All deny any wrongdoing.
