United Nations System
There are 15 members of the Security Council, consisting of five veto-wielding permanent members (China, France, Russia, the United Kingdom, and the United States) and 10 elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time.
European Union and the United Nations
The European Union (EU) has had permanent observer status at the United Nations (UN) since 1974, and has had enhanced participation rights since 2011. The EU itself does not have voting rights but it is represented alongside its 28 members, two of which (France and the United Kingdom) are permanent members of the Security Council.
