The Arraiolos Group is an informal meeting of Presidents of parliamentary and semi-presidencial European Union member states, held roughly once in a year. A political forum for the heads of state of parliamentary republics and also some semi-presidential republics (as opposed to constitutional monarchies or countries governed by a presidential system) whose role, according to the respective constitutions, may range from being significantly executive to largely ceremonial. It deals with questions and problems concerning the current state and future development of the EU as well as how to approach the challenges of globalisation.
