What is the United Nations Security Council?

The United Nations Security Council (UNSC) is the most powerful organ of the United Nations, with primary responsibility for the maintenance of international peace and security. Established under Chapter V of the UN Charter (1945), it is the only UN body whose resolutions are legally binding on all 193 UN member states.

The UNSC consists of 15 members: 5 permanent members (P5) — the United States, Russia, China, France, and the United Kingdom — each possessing veto power, and 10 non-permanent members elected by the UN General Assembly for two-year terms. The P5's veto power means that a single "no" vote from any permanent member can block any substantive resolution, regardless of the support of the remaining 14 members.

India has served as a non-permanent member 8 times (most recently 2021-22) and is a leading contender for a permanent seat as part of the G4 grouping (India, Germany, Japan, Brazil).
