UN Security Council Reform: What 'The World Is Bigger Than Five' Means

Why It Matters

UN Security Council reform asks who should hold the world's most powerful decision-making seats on peace and security, and under what rules. 'The world is bigger than five' is the slogan President Recep Tayyip Erdoğan uses at the UN General Assembly to argue that a Council dominated by five permanent members, set in 1945, cannot speak for 193 member states. Reform has been debated for more than three decades without a new structure, because the states that would have to approve it disagree on the model and because the five permanent members can block any Charter change.

Background

How the Council is built

The Security Council is the only UN organ whose decisions are legally binding on all members under Chapter VII of the UN Charter. Article 23 sets out its composition, and Article 27 sets out how it votes.

• Five permanent members (P5): China, France, Russia, the United Kingdom and the United States. They hold their seats indefinitely.
• Ten elected members: chosen by the General Assembly for two-year terms and not immediately re-eligible. Seats are allocated by regional group: three for Africa, two for Asia-Pacific, two for Latin America and the Caribbean, two for the Western European and Others Group, and one for Eastern Europe.
• Voting: substantive decisions need nine affirmative votes and no negative vote from a permanent member (Article 27). A single P5 'no' is the veto.

The only enlargement

The original Council of 1945 had 11 members: five permanent and six elected. As UN membership grew through decolonization, the General Assembly adopted an amendment in 1963 raising the Council to 15 members. It entered into force in 1965. The permanent membership has not changed in composition since, apart from the seat of China passing to the People's Republic of China in 1971 (General Assembly resolution 2758) and the Russian Federation continuing the Soviet seat after 1991.

Why changing it is hard

Article 108 of the Charter requires an amendment to be adopted by two-thirds of the General Assembly and ratified by two-thirds of member states, including all five permanent members. This gives each P5 state an effective veto over reform of the veto itself.

Timeline of the reform debate

Key Players & Positions

The reform models

A recurring pattern explains the shape of the UfC group: many of its leading members are regional counterparts of G4 aspirants, and they argue that new permanent seats would create new privileges rather than greater accountability.

The permanent five

The P5 do not share a single view, and each speaks through its own statements in the General Assembly and the IGN process.

• United States: has said it supports adding permanent seats for African states and a rotating seat for small island developing states, but has not endorsed extending the veto to new members.
• United Kingdom and France: have long supported new permanent seats for the G4 states and stronger African representation. France also champions voluntary suspension of the veto in mass-atrocity situations.
• Russia: says it backs greater representation for Asia, Africa and Latin America and has expressed support for Brazil and India, while opposing changes it sees as weakening the Council's effectiveness or the veto.
• China: says it supports increasing representation of developing countries, especially African states, and calls for reform to be agreed by broad consensus rather than forced by a vote.

All five insist the veto itself is not up for removal, which is why most proposals focus on its use rather than its existence.

Source Comparison

Coverage of the issue differs mainly in emphasis. Western and international outlets often present reform as a technical bargain among aspirants, while Turkish primary sources present it as a question of legitimacy and fairness.

Neither framing is complete. The UN's own General Assembly documents and IGN co-chair texts show that disagreement is not only between Türkiye and the P5, but among regional groups and within the African Union over veto rights and the number of seats.

Why Progress Is Slow

• P5 consent is required for Charter change, and none will vote to weaken its own status.
• Regional rivalries mean that every proposed permanent seat is contested by a neighboring state.
• Split priorities: some states want seats, others want restraint, others want accountability.
• Process: the IGN works by consensus on agenda and has repeatedly rolled over without a negotiating text accepted by all.

Incremental steps, such as the 2022 veto initiative, have therefore been easier to achieve than structural change.
