The Oireachtas works with other parliamentary assemblies within Europe and beyond. Foreign parliamentarians regularly visit the Oireachtas to study policy issues and have discussions with their Irish counterparts, and Members of the Oireachtas travel to other parliaments too.
The Oireachtas also participates in European and international parliamentary assemblies. Ireland is a member of the Inter-Parliamentary Union, the Parliamentary Assembly of the Council of Europe and the Parliamentary Assembly of the Organisation for Security Co-operation in Europe.
The purpose of all of this work is to foster good working relationships, promote debate, create a greater understanding on issues of mutual concern and agree common positions where possible.
The political interaction and relationship between the EU institutions and the Houses of the Oireachtas is handled mainly by the Oireachtas Joint Committee on European Union Affairs. The Oireachtas is represented to the EU institutions by the Oireachtas National Parliament Office in Brussels.
The Inter-Parliamentary Union (IPU) is the international organisation of parliaments. It is the focal point for world-wide parliamentary dialogue and works for peace and co-operation among peoples and for the firm establishment of representative democracy.
The Organization for Security and Co-operation in Europe Parliamentary Assembly (OSCE PA) provides a forum for parliamentary dialogue on security between the 57 OSCE member states.
The Oireachtas Women's Parliamentary Caucus hosted the first International Congress of Parliamentary Women's Caucuses in Dublin Castle on 9-10 September 2018.
