Ugandan diplomat and former United Nations Under-Secretary-General Olara Otunnu is positioning himself as a strong contender for the UN Secretary-General position, as the race to succeed António Guterres gathers momentum. Uganda formally nominated Otunnu in July, presenting him as a veteran diplomat with more than four decades of experience in international affairs, government and the United Nations system. His extensive background places him among the candidates seeking to lead the world body from January 2027.
Otunnu’s strongest advantage is his deep familiarity with the United Nations itself. He previously served as Uganda’s Permanent Representative to the UN and later became the organisation’s Under-Secretary-General and first Special Representative for Children and Armed Conflict. During his tenure, he helped elevate the protection of children affected by war onto the UN Security Council’s peace and security agenda and contributed to the development of a monitoring and reporting mechanism that remains in use today.
His diplomatic record also includes an unusual connection to the very process through which the next Secretary-General will be selected. Otunnu developed the informal “Otunnu Formula” for Security Council straw polling while serving as Council president in 1981. The procedure became established practice for assessing candidates for the UN’s top position. His experience in consensus-building could therefore be particularly valuable at a time when the organisation faces deep divisions among member states.
Otunnu is also campaigning on the argument that the UN needs meaningful institutional reform and renewed moral authority. During his interactive dialogue with UN member states and civil society in New York on August 19, he called for continued reform and warned against maintaining a system that he considers overly bureaucratic and inefficient. He also stressed the need for the organisation to help bridge growing divisions in the international community and restore confidence in multilateral cooperation.
His candidacy comes at a particularly challenging moment for the United Nations, with wars, geopolitical rivalries, humanitarian emergencies, climate concerns and emerging technologies placing new demands on the organisation. Otunnu has highlighted conflict resolution, institutional reform, climate action and responsible approaches to artificial intelligence among the issues that should receive greater attention. His previous work on armed conflict and international peace gives him direct experience with several of the challenges confronting the UN today.
While the competition remains open and other highly experienced candidates are also seeking the position, Otunnu brings a combination of senior UN experience, diplomacy, peacebuilding and institutional knowledge that could make him a compelling candidate. The final decision will depend heavily on the UN Security Council, including the need for a recommended candidate to avoid a veto from any of its five permanent members before the General Assembly makes the appointment. For Uganda, his candidature represents an opportunity to put an experienced African diplomat at the centre of one of the world’s most important international leadership contests.
