Prosecutors in Lithuania are seeking a 20-year jail term for an Irish man suspected of trying to buy arms and explosives for an Irish dissident republican group.
Michael Campbell was arrested three years ago in the Baltic state in an international sting operation with Irish police.
Campbell, 36, from Dundalk, County Louth, allegedly handed 10,000 euro (£8,500) to an undercover Lithuanian agent posing as a weapons supplier.
Lithuanian prosecutor Gedgaudas Norkunas said in the capital Vilnius that prosecution witnesses had testified and the trial was nearing its conclusion.
The next session is scheduled for mid-February.
Campbell’s brother, Liam, is believed to be a senior Real IRA member.
