The President of the General Assembly, Annalena Baerbock, opened by framing the choice as one about custodianship of the Charter and its three pillars, and said the point of one shared stage was to hear how each would define principled leadership, reform the organisation, and represent the world's eight billion people. The moderators, Haslinda Amin and Romaine Bostick of Bloomberg, ran a hard clock: several candidates were cut off mid-sentence, and where a position is truncated in the record this readout says so rather than completing the thought.
Where this sits in the selection. The Secretary-General is appointed by the 193-member General Assembly on the Security Council's recommendation, where any permanent member can block a candidate. Straw polls — informal, unrecorded votes marking each candidate as encourage, discourage or no opinion — were expected from the end of July 2026, a recommendation in September, and the appointment later in the year. The next Secretary-General takes office on 1 January 2027. This town hall is therefore the last major moment with the candidates' positions on the public record side by side, before the decisive phase moves behind closed doors.
The questions came in three rounds. Each opened with one question put to all six candidates, then moved to individually targeted questions — some from the moderators, some from the floor.
Round 1 — Crisis and conflict
To all six: the Strait of Hormuz crisis closed a critical shipping lane and the Security Council could not adopt a resolution. What keeps the UN meaningful when diplomacy inside the Council fails?
| Candidate | Individual question | What they answered |
| Michelle Bachelet |
Gaza, and what to do when moral authority is not enough |
Moral authority is always needed but must be paired with tools. Pressed for a mechanism, she named Article 99, and Uniting for Peace as the Assembly's route when the Council is deadlocked — plus field presence and building allies who can shift an outcome. |
| Macky Sall |
What he would champion without Security Council backing |
The Charter gives the office a facilitator role and an early-warning function; he would use quiet, preventive diplomacy and speak to belligerents, permanent members included. Asked how, he pointed to meeting Putin and travelling to Sochi and Kyiv as African Union chair when few supported it. |
| Carolyn Rodrigues Birkett |
Making the Council effective when it is paralysed by vetoes |
There is always space for the Secretary-General. Drawing on her own Council service, she would use the office's neutrality and the UN's field footprint to put concrete proposals to members: the Council may not act today but may act next week on that recommendation. |
| María Fernanda Espinosa |
Reorganising the UN so climate is cross-cutting, not environmental |
Noted more than 14 senior officials work on climate without working together. Called climate a symptom of consumption and production patterns, and the core problem one of implementation rather than knowledge — the agreements and technologies already exist. Asked which division she would break first, she named the link between climate, conflict and the human-rights pillar. |
| Rafael Mariano Grossi |
First steps when a permanent member wages a war of aggression |
Any member starting a war is serious enough for the Secretary-General to step in, permanent member or not. First restore the UN's credibility as a valid interlocutor, then use the Charter's tools — starting with talking and listening, and treating the conflict realistically by examining why force was used. |
| Rebeca Grynspan |
The Sahel, climate security and locally-rooted peacebuilding |
Climate is becoming a peace and security issue, with most displacement now climate-driven. The UN is unique but not alone: it should partner with regional and local organisations that have people on the ground. On local ownership, the real reform is at country level — the UN is supply-driven when it should be demand-driven. |
Round 2 — UN reform and leadership
To all six: at the end of a first term, what would governments and people say the UN does better than it does today?
| Candidate | Individual question | What they answered |
| Rafael Mariano Grossi |
Influence versus authority — an example of using persuasion |
The IAEA established the only independent multilateral presence in a theatre of war, at Zaporizhzhia, and negotiated six Russia–Ukraine ceasefires to allow essential repairs. His conclusion: that is only possible through credibility, and by arriving at the real table with viable solutions. |
| Michelle Bachelet |
A major donor threatening funding over criticism of it |
She would speak. At UN Women a donor threatened to pull all its funding; she acted anyway, it did, and she sought funds elsewhere. As High Commissioner she was likewise pressed not to release documents and released them — independence being the only basis on which all 193 members can feel represented. |
| Rebeca Grynspan |
What she would protect at all costs under financial pressure |
Rejected the premise — opening with what to cut is the worst way to negotiate. Would build on the Assembly's liquidity decision and protect the Charter and three pillars while becoming more agile. Pressed on unprecedented arrears: the priority is a stable financial path, since an organisation that cannot predict its income cannot be strategic. |
| Macky Sall |
Preserving independence from the permanent five |
His record already shows independence, and his diplomacy excludes no one. The liquidity crisis conceals a crisis of trust for which reform is the pretext; he would open the organisation's accounts and reform proposals to all member states — after which it is for each to meet its obligations. |
| María Fernanda Espinosa |
Which Security Council reform she would champion |
Better working methods and effectiveness, including a larger role for the Secretary-General as honest broker and provider of options and scenarios. On composition she declined to take a side: reform is entirely in member states' hands and the office's job is secretariat support. Asked directly about an African permanent seat, she said the Secretary-General has no role backing any particular position. |
| Carolyn Rodrigues Birkett |
Staff morale, managerial efficiency and accountability |
Would continue the Secretariat reform already begun, using technology. A Secretary-General is only as strong as the team around her; member states want a Secretariat that looks like the world it represents, making under- and unrepresented countries a priority. Change brings trepidation, and she hopes to be a motivator through it. |
Round 3 — Global challenges and opportunities
To all six: many of the world's most consequential decisions are made by private companies rather than governments. What role should the Secretary-General play toward powerful private actors?
| Candidate | Individual question | What they answered |
| Rebeca Grynspan |
Trade shaped by geopolitics, and economic fragmentation |
In a multipolar world without multilateralism, fragmentation follows — she treats multipolarity and multilateralism as one question, not two. Asked what would change powerful states' behaviour, she pointed to trade proving more resilient than predicted, because regional agreements and integration kept setting workable rules even as trade was weaponised globally. |
| Rafael Mariano Grossi |
Whether the UN should set global rules for autonomous weapons |
Argued against an IAEA-for-AI: frontier models are built diffusely across jurisdictions, making a top-down, over-normative approach extremely difficult. Wants a collaborative platform to agree behavioural rules without stifling innovation, keeping a human in the loop. Nuclear-style verification would be an illusion, since IAEA safeguards rest on the material balance of tangible things. |
| Carolyn Rodrigues Birkett |
The unlearned lesson of COVID-19, and the next pandemic |
Stressed preparedness: many countries never recovered, and the pandemic set back the Sustainable Development Goals. Existing mechanisms, the WHO included, leave the world better prepared — but without financing and vaccine access it would again be survival of the fittest. On vaccine hoarding, the Secretary-General would have to use her voice, though this needs all members' cooperation. |
| María Fernanda Espinosa |
Selling climate adaptation finance as investment, not aid |
Wealthy nations should not need convincing: the evidence already shows adaptation reduces migration and protects livelihoods and prosperity. Called for rebalancing investment between mitigation and adaptation and resilience. The mechanisms exist; what is missing is implementation and political will, which the Secretary-General is well placed to drive for vulnerable countries. |
| Macky Sall |
Reforming the global financial architecture and the debt burden |
Would launch a global discussion on reforming the international financial architecture. The burden is not the size of developing countries' debt but its terms — borrowing costs five to eight times higher than developed countries pay. Credit rating agencies belong in that discussion alongside member states and the financial institutions, with private finance mobilised and its risks mitigated. |
| Michelle Bachelet |
Prioritising and funding the human-rights pillar |
Has seen firsthand how central human rights are to preventing conflict and to peacebuilding, and would speak up when appropriate. Would strengthen coordination among agencies working on human rights in the field, resist cuts to a chronically underfunded pillar — she put the High Commissioner's share of the regular budget in the low single digits — and mobilise voluntary contributions. |
A closing all-candidate question asked for the greatest threat facing the world's peoples, and each candidate then had two minutes on their first hundred days. Those closing lists are specific enough to be checked later, and are set out in the ledger below.
