Who Chooses the UN Secretary-General? The Behind-the-Scenes Battle Between the Charter, Veto, and Consensus

The position of United Nations Secretary-General is among the most important and sensitive international posts, not only due to the broad political and administrative responsibilities undertaken by its holder, but also because of the complex mechanism governing its selection, which combines legal provisions with considerations of international balance. Although the UN Charter vests the General Assembly with the authority to appoint the Secretary-General, this power is contingent upon a prior recommendation from the Security Council, thereby granting the five permanent members decisive influence over the identity of the individual who assumes the post. Article 97 of the Charter stipulates that the Secretary-General shall be appointed by the General Assembly upon the recommendation of the Security Council. This means that the selection process involves two stages: the first and most critical takes place within the Security Council, where the recommendation on the candidate is issued, and the second occurs in the General Assembly, which makes the final appointment. Legally, the General Assembly cannot appoint a candidate who has not received the Council’s recommendation, a provision that assigns the Security Council a pivotal role in the process.

Article 27 of the Charter is particularly significant in this context, as the Security Council’s recommendation on the Secretary-General is subject to the voting rules for non-procedural matters. This requires at least nine affirmative votes and no negative vote from any of the five permanent members: the United States, Russia, China, France, and the United Kingdom. Consequently, it is not sufficient for a candidate to secure a majority of votes among Council members; the candidate must also not face opposition from any permanent member. However, an abstention by a permanent member does not constitute the exercise of a veto and does not prevent the adoption of the recommendation if the required number of votes is met.

Despite the brevity of the Charter’s text regarding the appointment of the Secretary-General, the selection process has evolved through practice to become more procedurally open. General Assembly Resolution 69/321, adopted in 2015, contributed to enhancing transparency by expanding the scope of nomination announcements, making information about candidates available, and organizing interactive dialogues that allow member states to learn about their programs and visions for the future of the Organization. Nevertheless, these developments have not altered the core of the constitutional mechanism, as the recommendation remains with the Security Council and the appointment with the General Assembly.

Among the most prominent tools that have evolved within the Council’s practice are so-called informal straw polls, which aim to gauge Council members’ attitudes toward candidates before moving to formal voting. Each member is asked to choose one of three options: “Encouragement,” “Discouragement,” or “No View.” These straw polls do not constitute formal decisions or binding procedures under the Charter, and their results are typically not officially disclosed; rather, they are circulated through leaks and media reports. In some rounds, the Council has used colored ballots to distinguish between the votes of the five permanent members and those of elected members, helping to determine whether opposition stems from a permanent or an elected member. However, these ballots do not reveal the identity of the country casting the vote, and their use is not mandatory.

It is important to distinguish between selecting “Discouragement” in a straw poll and the use of a veto. The former is an informal political indicator, whereas a veto is only exercised when a negative vote is cast by a permanent member during the formal voting process of the Security Council.

The selection process is not limited to legal rules and institutional procedures; it is also influenced by unwritten political traditions, the most prominent of which include adherence to geographical rotation, gender balance, and the avoidance of appointing a national from any of the five permanent members of the Security Council. These considerations do not constitute binding legal requirements, but they carry significant weight in political consultations. Since the organization’s founding, the post has been held by nine individuals from different regional groups, with no candidate from the Eastern European Group having reached the position thus far. The current competition gains additional historical significance amid multiple female candidacies and rising calls for a woman to become Secretary-General for the first time since the United Nations was established in 1945. If achieved, this would mark a major turning point in the organization’s history and a symbolic step toward strengthening women’s presence at the highest levels of international leadership.

The ongoing competition in 2026 is aimed at selecting the tenth Secretary-General, succeeding António Guterres, whose term ends on December 31, 2026, with his successor assuming office on January 1, 2027. The process has seen several rounds of informal straw polls, during which several candidates emerged, including Rebecca Greenspan of Costa Rica, Rafael Grossi of Argentina, Caroline Rodrigues Berkett of Guyana, and Lana Nusseibeh of the United Arab Emirates, along with Turkish candidate Firdousen Senirli Oglu, who joined the race at a later stage. The eighth round, held on November 5, 2026, strengthened Greenspan’s position, as she received 12 votes of encouragement and three votes of discouragement, with no abstentions, marking the best result achieved by any candidate up to that point. Grossi came in second with nine votes of encouragement, followed by Rodrigues Berkett with eight, then Nusseibeh with seven, while Senirli Oglu received three votes of encouragement and eight votes of discouragement.

These results indicate Greenspan’s lead in the straw polls, but they do not determine the outcome of the competition. The eighth round used non-colored ballots, which do not allow for the separate identification of the positions of the five permanent members of the Security Council. Moreover, obtaining nine or more votes of encouragement in a straw poll does not equate to receiving a recommendation from the Security Council, which is issued only through a formal vote in accordance with the Charter’s provisions.

This competition highlights a clear paradox within the United Nations system: while modern procedures aim to enhance transparency and broaden the participation of member states, the decisive phase remains governed by closed-door negotiations and political understandings within the Security Council. Consequently, the fate of candidates depends not solely on their qualifications and platforms, but on their ability to secure acceptance from major powers and avoid opposition from any of the five permanent members. Ultimately, the selection of the Secretary-General is not merely a contest among individuals, but a test of the ability of member states, particularly major powers, to reach consensus on a figure who is expected to represent the entire international organization and to perform its duties independently and impartially. Between the provisions of the Charter and the balance of international power, the recommendation issued by the Security Council remains the decisive gateway to the Secretary-General’s post, while political consensus remains the most critical factor in determining who will lead the United Nations in the coming years.
