A proposed assembly of delegated or elected representatives of the world's peoples. The best-known proposal is a UN Parliamentary Assembly, not yet established.
In more detail
Cosmopolitan democrats such as Held and Archibugi propose a global parliamentary assembly as one layer of democratic governance, not as a world government. The 2007 appeal for a UN Parliamentary Assembly envisaged a consultative body first of national parliamentarians, later possibly directly elected. The European Parliament, elected directly since 1979, is a regional parallel.
