The Security Council consists of 15 members, 5 permanent and 10 non-permanent. The U.S.A., U.K., U.S.S.R., China and France are the permanent members. The ten non permanent members are elected by the Assembly for two years’ term (five every alternate year). Retiring members are not eligible for immediate re-election.
The Security Council is the most important body in the U.N.O. Inside the Security Council effective influence is wielded by the permanent members. The concurrence of permanent members is necessary for all vital decisions of the Security Council affecting international peace and security.
