Permanent members of the United Nations Security Council
The permanent members of the United Nations Security Council (also known as the Permanent Five, Big Five, or P5) are the five states which the UN Charter of 1945 grants a permanent seat on the UN Security Council: China (formerly the Republic of China), France, Russia (formerly the Soviet Union), the United Kingdom, and the United States. These countries were all allies in World War II, which they won. They are also all nuclear weapons states. A total of 15 UN member states serve on the UNSC, the remainder of which are elected. Any one of the five permanent members have the power of veto, which enables them to prevent the adoption of any "substantive" draft Council resolution, regardless of its level of international support.

Italy, the third main defeated power in WWII and now the UN's sixth-largest funder, leads a movement known as the Uniting for Consensus in opposition to the possible expansion of permanent seats. Core members of the group include Canada, South Korea, Spain, Indonesia, Mexico, Pakistan, Turkey, Argentina and Colombia. Their proposal is to create a new category of seats, still non-permanent, but elected for an extended duration (semi-permanent seats). As far as traditional categories of seats are concerned, the UfC proposal does not imply any change, but only the introduction of small and medium size states among groups eligible for regular seats. This proposal includes even the question of veto, giving a range of options that goes from abolition to limitation of the application of the veto only to Chapter VII matters.
