As the selection process for the 10th Secretary-General of the United Nations begins, several prominent global figures have emerged to succeed the outgoing chief, António Guterres. The five-year term is set to commence on January 1, 2027. Below is a detailed look at the primary candidates and their strategic visions for the world’s most significant diplomatic office.
Rafael Grossi (Argentina)
A 65-year-old career diplomat, Grossi currently serves as the Director General of the International Atomic Energy Agency (IAEA). He has built a reputation as a “man of action” through high-stakes diplomacy in Iran and his direct involvement in securing the Zaporizhzhia nuclear power plant in war-torn Ukraine.
- Key Strength: Proven ability to navigate crises and maintain dialogue with the five permanent members of the UN Security Council.
- Vision: Strengthening multilateral institutions to ensure they provide a positive impact even during times of deep international division.
Rebeca Grynspan (Costa Rica)
Grynspan, 70, is a seasoned economist and former Vice President of Costa Rica. Currently leading the UN Conference on Trade and Development (UNCTAD), she presents herself as a reform-minded multilateralist.
- Historic Potential: If elected, she would be the first woman to serve as UN Secretary-General.
- Vision: Promoting a more “agile” UN that collaborates effectively with diverse stakeholders while maintaining a steadfast commitment to peace, development, and human rights.
Michelle Bachelet (Chile)
A heavyweight in international politics, the 74-year-old Bachelet is a two-time President of Chile and the former UN High Commissioner for Human Rights. Despite her vast experience, her candidacy faces domestic and international hurdles.
- Challenges: The current right-wing Chilean government withdrew its support, though she maintains backing from Brazil and Mexico. She also faces criticism from U.S. conservatives regarding her past reports on human rights in China.
- Experience: Deep institutional knowledge from leading UN Women and the Human Rights Council.
Macky Sall (Senegal)
The 64-year-old former President of Senegal leverages his experience as a head of state to argue for a leadership style rooted in executive governance.
- Platform: Focuses heavily on the needs of developing nations, particularly regarding debt relief and infrastructure.
- Reformist Stance: He is a vocal advocate for restructuring the UN Security Council to include permanent representation for African nations, aiming for a “reinvented multilateralism.”
Comparison of Candidate Profiles

The selection of the Secretary-General remains a complex diplomatic exercise, requiring a recommendation from the Security Council—where the “P5” nations hold veto power—followed by a vote in the General Assembly.
