UN chief race enters decisive phase as new contender arrives

The contest to replace current UN chief Antonio Gutteres has entered a decisive phase. Rebeca Grynspan remains the leading candidate, but UAE Minister of State Lana Nusseibeh has joined the race. Her candidacy has increased attention because no woman has ever led the UN since its establishment in 1945.

A recent informal Security Council straw poll gave Grynspan a narrow lead over Carolyn Rodrigues-Birkett and Rafael Grossi. However, two opposing votes meant the process was relaunched, allowing additional candidates to participate. Nusseibeh then announced her candidacy and presented peace, security, development, human rights, and organisational reform as priorities.

The Security Council must select a candidate by the end of December. The winner needs at least nine votes and no opposition from any permanent member. The General Assembly will then confirm the appointment. Nusseibeh joins several other candidates, so Grynspan’s lead is significant but not decisive.

The UN Secretary-General leads the United Nations and serves as its most prominent international representative. The position involves guiding the organisation’s work, speaking with governments, and drawing attention to major global crises. It is both a diplomatic and managerial role, because the secretary-general must build agreement while helping the UN deliver its programmes.

In this race, candidates describe different priorities for that work. Lana Nusseibeh places peace and security at the centre, while also promising action on development, human rights, and organisational reform. She says the secretary-general should bring countries together, act earlier, and pursue diplomacy until it produces concrete results.

The office matters because the UN includes countries with competing interests. Its leader cannot command governments, but can create space for negotiation, coordinate international efforts, and press states to cooperate. The next secretary-general will therefore need credibility with powerful countries and the ability to build common ground.

The selection process begins with candidates campaigning for support among UN member states, especially the 15-member Security Council. Council members use informal straw polls to gauge backing. The process can change when candidates receive opposing votes, as happened here, allowing new contenders to enter the race.

The key mechanism is the Security Council vote. A candidate needs at least nine votes and must avoid opposition from any of the five permanent members: the United States, the United Kingdom, France, China, and Russia. This gives those five countries a blocking role even if a candidate has wider support.

After the Council chooses a nominee, the UN General Assembly confirms the appointment. The Council must act by the end of December to replace Antonio Gutteres. Grynspan’s narrow straw-poll lead is therefore important, but it does not guarantee victory. Nusseibeh’s entry has made the final phase more competitive.

The voting threshold is nine votes in the 15-member Security Council. Meeting that number is necessary, but it is not enough by itself. The candidate must also avoid opposition from every permanent member, making the process depend on both broad support and agreement among the most powerful Council states.

The five permanent members are the United States, the United Kingdom, France, China, and Russia. Their ability to block a candidate is central to the selection process. A contender can therefore have substantial support and still fail if one permanent member opposes the nomination.

This rule helps explain why the race remains unsettled despite Rebeca Grynspan’s lead in an informal straw poll. The Council has until the end of December to choose Antonio Gutteres’s successor. The General Assembly then confirms the appointment, but it does not replace the Council’s decisive role.

The biggest possible change is historical representation. The UN has never had a female secretary-general since its establishment in 1945. If Lana Nusseibeh or another woman wins, that barrier would end and the organisation’s top office would reflect a wider range of leadership experiences.

Nusseibeh’s election would carry additional significance. The article says she would be the first secretary-general of Palestinian descent and the second from the Arabic-speaking world, after Egypt’s Boutros Boutros-Ghali. Her background includes senior diplomacy, work at the UN, and leadership of the UAE’s successful Security Council bid.

A woman’s election would not automatically resolve the UN’s political challenges. The secretary-general would still need nine Council votes, no permanent-member opposition, and General Assembly confirmation. Nusseibeh says she is running because of her diplomatic outlook and optimism about the UN, not simply because she is a woman.

A secretary-general’s background can influence how the person approaches the UN’s central problems. Diplomats may bring negotiation skills and relationships with governments. Development specialists may focus on economic and social priorities. Human rights experience can sharpen attention to protections and accountability, while peace negotiators may emphasise dialogue and conflict prevention.

The candidates illustrate this range. Nusseibeh highlights quiet diplomacy and cites humanitarian access to Gaza through Resolution 2720. Grynspan is a former Costa Rican vice president. Grossi leads the International Atomic Energy Agency, while Rodrigues-Birkett is a former foreign minister. Other contenders include former Ecuadorian Foreign Minister Maria Fernanda Espinosa and former Senegalese President Macky Sall.

These backgrounds do not determine the result or guarantee effectiveness. The winner must still build Security Council support and avoid permanent-member opposition. The next leader will also need to balance peace and security with development, human rights, and organisational reform.

In a multipolar world, power and influence are spread among countries with different interests. The UN provides a common forum where governments can discuss conflicts, humanitarian needs, development, and rights. It cannot force every government to agree, but it can make sustained diplomacy possible and give negotiations an international framework.

The article offers a concrete example through Nusseibeh’s diplomacy. During the UAE’s 2022 to 2023 Security Council term, she helped secure Resolution 2720, which opened the way for humanitarian aid deliveries into Gaza. She said visits by Council members to the Rafah crossing helped build support for the resolution.

Such cooperation can reduce conflict by creating shared facts, encouraging compromise, and producing limited agreements even when wider disputes remain. The next secretary-general will need to act early, bring countries together, and pursue talks until they deliver results. That is why diplomacy and institutional reform are central to this race.
