Northern Ireland police chief Sir Hugh Orde will be in Leinster House today to discuss the bombing of Kay's Tavern in Dundalk.
The PSNI chief constable will meet an Oireachtas sub-committee over the 1975 atrocity.
Two men were killed when a car bomb was planted by the Red Hand Commandos, a group closely associated with the Ulster Volunteer Force, outside the tavern on Crowe Street, Dundalk, Co Louth, in December 1975.
Sir Hugh, and the Historical Enquiries Team, will discuss the attack with the Sub-Committee on the Barron Report on the bombing of Kay's Tavern, Dundalk, of the Joint Committee on Justice, Equality, Defence and Women's Rights.
The Barron Report deals with nine bombings on both sides of the Border between 1974 and 1976 in which 18 people were killed, and many more injured.
These include the Dundalk bombing, the Dublin airport bombing and the Miami Showband killings.
