Meetings of the Council take the form of "regular and frequent" sectoral meetings between ministers from the Government of Ireland and the Northern Ireland Executive. Plenary meetings, attended by all ministers and led by the First Minister and deputy First Minister and the Taoiseach, take place twice a year. Institutional and cross-sectoral meetings, including matters in relation to the EU or to resolved disagreements, happen "in an appropriate format" on a "ad hoc" basis. The Council has a permanent office located in Armagh, Northern Ireland, staffed by a standing secretariat.
