Perhaps the most controversial reform is an expansion of the 15-member Security Council. Three draft resolutions have been introduced in the General Assembly, including one by Brazil, Germany, India, and Japan to increase council membership to 25.
All decisions to reform the Security Council must be approved by two-thirds -- or 128 votes -- in the 191-member General Assembly.
The council's five permanent members -- the United States, Russia, Britain, China, and France -- have veto power.
