An ex-IRA man who has vowed to continue to help with the search for the remains of Disappeared soldier Robert Nairac will speak in Cork at the premiere of a new documentary.

Former republican prisoner Martin McAllister described the situation as an "open running sore" in south Armagh, where the Grenadier Guards captain was last seen alive in 1977.
