The United Nations Security Council (UNSC) reform is one of the primary issues of contemporary global governance discourse, particularly within the BRICS (Brazil, Russia, India, China, and South Africa) grouping. This group is collectively vocal about the overdue need to reform the UNSC into a more representative, democratic, effective and efficient structure that reflects the realities of the twenty first century. However, individual foreign policies of BRICS member states reflect significant divergences, particularly on how the UNSC should be reformed. For instance, India and Brazil are members of the G4 UNSC reform lobby group, which has clear differences with South Africa’s Ezulwini Consensus lobby group on the question of veto power. On the other hand, Russia and China seem not to be fully committed to the idea of UNSC reform. It is against this background that this chapter, through a realist perspective, provides an analysis of what informs these divergent postures among BRICS member states on how UNSC reform should take shape. In addition, the chapter provides an analysis of the implications of these divergences on African security, considering that over 50 percent of UNSC meetings and 70 percent of its resolutions pertain to the continent. This is critical, considering that the development of the African continent is largely dependent on the preservation of peace and security. This chapter relied on qualitative secondary sources and adopted an analytical explanatory approach to analyse data.
