Each year the Isle of Man branch sends two delegates to the Commonwealth Parliamentary Conference (the Plenary Conference) at which parliamentary and political issues are discussed in an effort to improve the way parliaments work and to broaden the understanding of members. The same delegates attend the separate Conference of Members from legislatures serving smaller populations (the Small Countries Conference).
The 64th Commonwealth Parliamentary Conference was held in Uganda in September 2019. Summary reports of conferences are published and sent direct to all Heads of Governments within the Commonwealth, Leaders of the Opposition, selected Ministers and relevant international organisations so that the views of Commonwealth members may be reflected.
The branch also sends four delegates each year to the Conference of the British Islands and Mediterranean Region. The 49th Regional Conference was held virtually in 2020 and was hosted by Malta, and the 50th Regional Conference was held in Belfast in 2021.
The member branches of the Region are: Alderney, Cyprus, Falkland Islands, Gibraltar, Guernsey, Isle of Man, Jersey, Malta, Northern Ireland, St Helena, Scotland, United Kingdom and Wales. The UK branch hosts an annual seminar on parliamentary practice and procedure which has been held at Westminster since 1951. From time to time the branch is invited to send a member to participate in these seminars. The branch also sends members on study visits to other branches and hosts return visits. It welcomes visiting parliamentarians and on request will contact the Secretariat of any member branch which any of our own members intends to visit, whether officially or privately.
Members receive copies of the Association's journal The Parliamentarian, which contains articles, reports on political and constitutional developments, description of procedural rulings, parliamentary reports and review of parliamentary books written primarily by and for members and officials, in addition to a newsletter on CPA and Commonwealth parliamentary and political developments entitled First Reading.
The Association also operates the Parliamentary Information and Reference Centre which processes enquiries on political, parliamentary and constitutional matters.
