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 EU holds its observer membership alongside the full memberships of all its 28 member states, two of whom (France and the United Kingdom) are permanent veto-holding members of the UN Security Council (UNSC). Furthermore, where the EU has a defined position on a UNSC agenda item, those states shall request the High Representative to be invited to present the EU's position. This however does not impact on the right of those states to form their foreign policy (stated in ).
