United Nations Security Council
Along with the five permanent members, the Security Council of the United Nations has temporary members that hold their seats on a rotating basis by geographic region. Non-permanent members may be involved in global security briefings. In its first two decades, the Security Council had six non-permanent members, the first of which were Australia, Brazil, Egypt, Mexico, the Netherlands, and Poland. In 1965, the number of non-permanent members was expanded to ten.
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.
