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.

It is also eligible for having its nationals elected as President of the United Nations General Assembly in years ending with 2 and 7; most recently, Vuk Jeremić of Serbia was elected to this position in June 2012 and was the office holder of the Sixty-seventh session.
