U.N. Secretary-General Candidates May Agree More than They Differ on the Way Forward

The 15 members of the United Nations Security Council held their first straw poll last week for the seven candidates vying to succeed António Guterres as the next secretary-general. The most important number in these polls is the “discouragement” votes that could indicate a potential veto by one or more of the five permanent members — China, France, Russia, the United Kingdom, and the United States. By this count, the front runner is Rebeca Grynspan with one discouragement, shortly followed by Carolyn Rodrigues Birkett, Rafael Grossi, and Maria Fernanda Espinosa with two discouragements each. The job turns over only once a decade, and whoever takes office on Jan. 1, 2027, will lead an organization under serious strain. But the more revealing feature of this race is not who is ahead. It is how little the candidates disagree about what is wrong.

The consensus runs deep: none of the seven is advocating for a retreat from international cooperation through the United Nations, or for a diminished role for the organization itself. They share a common premise that the U.N. remains indispensable but is struggling to meet the demands of a rapidly changing world. What divides them is narrower: how to correctly diagnose that struggle, and in what way and how forcefully the next secretary-general should act on it.

Claiming a Lane

Line up what the seven candidates are actually saying, and a pattern emerges. They agree on the disease, though with slight language variations — “trust,” “confidence,” “credibility” — and differ mainly on how they prioritize potential cures. Bachelet cites ”rebuilding trust in the United Nations,” arguing that confidence in the institution has eroded precisely when cooperation is most needed. Espinosa sees a crisis in the institution’s “duty to deliver” — the gap between what the U.N. promises and what it produces.

Grynspan and Grossi both serve (or served prior to their campaign) on the Chief Executive Board of Guterres’ U.N., yet, their campaigns seem to pull away from their prospective predecessor. Grossi characterizes the U.N.’s problem as one of leadership, arguing the system must prove its worth through “active diplomacy” and crisis management rather than administration. Grynspan emphasizes institutional legitimacy, contending that the U.N. must “chart a path for renewal” under the stewardship of the new secretary-general. For his part, Sall raises representation, calling to “safeguard unity” in international cooperation though the U.N.

These are real differences, but they are differences of emphasis inside a shared idea. No one is defending the status quo; everyone is describing a version of the same gap between the U.N.’s mandate and its capacity. The disagreement is over what they see as the U.N.’s comparative advantage in international cooperation and how they plan to capitalize on these advantages in a renewed U.N.

By the time Carolyn Rodrigues Birkett entered the race in mid-June, the major diagnostic lanes were already claimed. Her platform draws together themes that had surfaced across the campaign, from implementation to mediation, development finance, and multilateral cooperation. What was left to distinguish her was emphasis: where other candidates propose systemic changes to the system, she emphasizes the role of member states in setting the body’s direction, as well as returning to the U.N.’s achievements and the enduring relevance of the U.N. Charter.

What Kind of Secretary-General?

The sharper divisions among the candidates relate to the office and how much initiative its holder should take. Grossi has staked out a narrow activist position, focused on peace and security and arguing the next secretary-general should move to prevent and mediate conflicts rather than wait for instruction from member states. Espinosa stresses presence, insisting the U.N.’s top official belongs in conflict zones, as well as at the head of the table to take responsibility for internal budgets – in other words, close to crises inside and outside the system.

Grynspan emphasizes diplomatic risk-taking and a willingness to fail in pursuit of peace. Bachelet has focused on preventing violent conflict, especially by engaging with local dynamics before conflicts escalate. Otunnu, the latest entrant, casts himself as a bridgebuilder who would use the office’s “moral authority” to restore the institution’s effectiveness, though having announced his candidacy after public debates had passed, he has yet to face the General Assembly dialogue or Interactive Dialogues with stakeholders that publicly tested the others.

The distinctions among the candidates’ platforms are subtle, but they track a genuine question: should the secretary-general be a chief administrator who serves the Security Council’s will, or an independent diplomatic actor who shapes it? The candidates are answering differently and mainly in terms of general characterizations of lines of work, and the answer matters more than usual at a moment when the Council itself is often deadlocked.

Judged on the Running, Not Just the Race

The campaign has also become a test of how candidates conduct themselves and of whether their conduct, either during the campaign or in U.N. office previously, matches their diagnosis of a crisis of legitimacy and efficacy. Sall built his candidacy on representation, warning that the United Nations cannot be legitimate while much of the world goes underrepresented, yet he entered the race without African Union endorsement. On conflicts of interest, the candidate field has split: Grynspan and Espinosa both stepped away from their posts — Grynspan temporarily stepped aside as secretary-general of the U.N. Conference on Trade and Development, Espinosa took leave as executive director of the women’s leadership NGO GWL Voices — arguing candidates should avoid even the appearance of one; meanwhile, Grossi chose to remain at the head of the International Atomic Energy Agency, an autonomous U.N. body, while campaigning. Bachelet’s candidacy, meanwhile, has drawn organized opposition focused on her record when she was U.N. High Commissioner for Human Rights.

The Vetoes Behind the Vote

For all the public statements both in writing and in open debates, the decisive audience is the 15 member countries of the Security Council, and above all the five permanent members, each of whom can end any candidacy with a single veto, before the Council forwards a nominee to the General Assembly for final approval. Great-power politics have always governed this process: in 1996, the United States blocked a second term for Boutros Boutros-Ghali over the objections of the rest of the Council.

While the power of the veto hasn’t changed, the contest is more publicly visible today. The 2016 race introduced public hearings and candidate dialogues, and the current contest is already producing organized campaigns for and against individual candidates. UN Watch, a vocal critic of the U.N., has urged the Council to reject Bachelet’s bid, Republican lawmakers have called on the United States to veto her, and U.S. Ambassador Mike Waltz has publicly questioned her fitness for the role. An independent coalition of human rights activists started the NoNaMacky campaign looking into previous accusations of human rights violations under Sall’s presidency, and Iran has expressed vocal opposition to Grossi. Whether any of this proves decisive is unknowable, because the decision ultimately belongs to a Security Council that casts its votes behind closed doors.

The leaked July 30 straw poll results provided a first glimpse of insight. Grynspan led with one vote to discourage and 10 votes to encourage; tailed by Rodrigues Birkett, Grossi, and Espinosa, each with two discouragements, and nine, seven, and five encouragements, respectively. Below them, the field thinned quickly. Bachelet drew six encouragements but five discouragements. Espinosa and Otunnu drew heavy abstentions, with eight no-opinion ballots each, a sign that many positions remain unformed or deliberately withheld. Otunnu’s five discouragements indicate a Security Council that respects campaign transparency, discouraging a candidate who presented himself after the open debates. Sall managed six encouragements against seven discourage votes, the kind of split that historically pressures a candidate toward exit.

But the numbers conceal the fact that the straw poll is anonymous and makes no distinction between the five permanent, veto-wielding members of the Council and the 10 that are elected. Candidates, therefore, have no way to know publicly whether opposition comes from a country that can end the race or one that merely registers a preference. Nor will the public learn that information, as no record of the poll is kept, and the ballots are destroyed once counted, so even these figures reach the world only through diplomats briefing the press – again, either publicly or through leaks. Later rounds of Security Council straw polls will introduce color-coded ballots that separate permanent members from those elected, and only then will the vetoes behind the vote become more legible. Until that point, a candidate can top the poll and still be quietly doomed; another can trail and survive.

That is the real state of the race. The field is crowded, the candidates are perhaps more alike than different, and the early front-runner leads by a handful of soft, anonymous votes. What the candidates think about the United Nations is now largely on the record. What the permanent members think about the candidates is not — and that, not the vision statements, is what will decide who leads the organization into 2027.
