United Nations Security Council
The Security Council consists of fifteen members. The great powers that were the victors of World War II—the Soviet Union (now represented by Russia), the United Kingdom, France, China, and the United States—serve as the body's five permanent members. These permanent members can veto any substantive Security Council resolution, including those on the admission of new member states or candidates for Secretary-General. The Security Council also has 10 non-permanent members, elected on a regional basis to serve two-year terms. The body's presidency rotates monthly among its members.
United Nations Regional Groups
The Western European and Others Group (WEOG for short) has 28 members (15% of all UN members). It has a territory dispersed on all of the continents, but mostly centred in Western Europe and North America. In addition, the United States is an observer (see below). Including the United States, WEOG has 5 seats on the Security Council: three permanent seats (France, United Kingdom, United States), and two non-permanent seats. The Group also has 13 seats on the United Nations Economic and Social Council and 7 seats on the United Nations Human Rights Council. In the rotation of the post of the President of the United Nations General Assembly, the group is eligible for having its nationals elected to this post in years ending with 0 and 5; most recently, Mogens Lykketoft of Denmark was elected to this position in 2015.
