Ugandan diplomat Olara Otunnu has joined the contest to become the next secretary-general of the United Nations, the seventh contender to succeed Antonio Guterres when he steps down at the end of this year.
Otunnu, a former U.N. under-secretary-general who served as special representative for children and armed conflict, was nominated by Uganda in a letter dated July 24 to the presidents of the General Assembly and Security Council. General Assembly President Annalena Baerbock and Security Council President Zenon Ngay Mukongo forwarded the nomination and supporting documents to all 193 member states the following day, formally placing Otunnu in the race.
At 75, he is the oldest of the current candidates for a role Guterres has held for two five-year terms, and his entry comes unusually late in the campaign. Candidates already in the race took part in a public town hall hosted by the General Assembly on July 23, where they laid out their platforms and fielded questions from member states and civil society groups. Otunnu did not take part because his candidacy had not yet been announced.
A career that spans the UN system and Ugandan opposition politics
Otunnu served as U.N. Under-Secretary-General and Special Representative for Children and Armed Conflict from 1997 to 2005 under then-Secretary-General Kofi Annan, placing the protection of children in war zones on the Security Council’s agenda for the first time. Before that appointment, he served as Uganda’s permanent representative to the U.N. and briefly as the country’s foreign minister, from 1985 to 1986. He later led the International Peace Academy, now known as the International Peace Institute, as its president from 1990 to 1998.
Uganda’s foreign ministry credits Otunnu with introducing the straw-balloting system used to narrow the field of secretary-general candidates, a procedure diplomats have called the “Otunnu Formula” that has guided the selection process since 1981. His nomination will now be tested by the same mechanism he helped design decades ago.
Otunnu’s path to global diplomacy runs through Uganda’s opposition politics as much as its foreign ministry. He led the opposition Uganda People’s Congress and ran against President Yoweri Museveni in the 2011 presidential election, losing to the leader who has held power since 1986. His nomination by the same government he once challenged marks an unusual turn, since Uganda has not explained publicly how it arrived at the decision to back him. Otunnu holds a bachelor’s degree in jurisprudence from Oxford University and a master of laws from Harvard Law School. He received the Sydney Peace Prize in 2005 and the German Africa Prize in 2002.
Seven candidates, no clear frontrunner

The other candidates are Rafael Grossi of Argentina, director-general of the U.N.’s International Atomic Energy Agency; former Chilean President Michelle Bachelet; Rebeca Grynspan, a former vice president of Costa Rica; Maria Fernanda Espinosa, a former foreign affairs and defense minister of Ecuador; Carolyn Rodrigues-Birkett, a former foreign minister of Guyana; and Macky Sall, a former president of Senegal.
Otunnu is only the second African candidate in the race, joining Sall, and his entry has revived debate over the U.N.’s informal practice of regional rotation. Many diplomats had expected the next secretary-general to come from Latin America or the Caribbean, the only regional group that has not yet produced a U.N. chief under the current rotation pattern. There has also been support in some quarters for choosing the first woman to hold the position.
In his vision statement, Otunnu said he would prioritize institutional reforms already underway and would move immediately to support efforts to end major international conflicts, naming Ukraine, Gaza, Sudan, the Democratic Republic of Congo and Iran as areas requiring renewed diplomatic attention. He also proposed creating a dedicated U.N. body to oversee global rules on artificial intelligence and said climate action must move forward without undermining economic development in poorer nations. He described his goal as serving as “a bridge builder” able to “propose creative solutions in difficult situations.”
Guterres’ successor inherits an organization diplomats describe as being in crisis, facing pressure to reform a bureaucracy widely seen as bloated and to cut duplication across its many overlapping agencies. Should Otunnu win the post, Uganda would become the first East African country to produce a U.N. secretary-general since the organization’s founding in 1945, a milestone that would raise the country’s diplomatic profile even though the office itself answers to all member states rather than any single government.
The selection process moves into a more concrete phase this week with straw polls in the 15-member Security Council, intended to narrow the field of candidates. Other contenders can still enter the race before that process concludes. Diplomats say no candidate currently holds a clear advantage, and the outcome will likely hinge on avoiding a veto from any of the Security Council’s five permanent members, particularly China, Russia or the United States.
