Deputies Yorgos Germenis, Panagiotis Iliopoulos and Stathis Boukouras denied the charges against them in marathon plea sessions on Saturday and Sunday. Golden Dawn denies any involvement in Fissas's killing.

Up to nine Golden Dawn deputies may be charged with high treason, the penalty for which is life imprisonment, according to a report submitted to parliament on Tuesday calling for the lifting of parliamentary immunity for a further three MPs.

The state inquisitor has requested the lifting of parliamentary immunity for three Golden Dawn deputies: Giorgos Germenis, Panayotis Iliopoulos, and Stathis Boukaras.
