A Contested Race: Six Candidates, One Job, and a US Push for Reform

The six candidates vying to lead the United Nations took part in a debate at the General Assembly on Thursday, just days before the Security Council begins its informal voting on July 30. The 90-minute session, broadcast live, gave diplomats, UN staff and civil society representatives a chance to question the aspirants before the secret ballot.

The field includes Rafael Grossi of Argentina, former Chilean president Michelle Bachelet, Ecuador’s María Fernanda Espinosa, Costa Rica’s Rebeca Grynspan, Guyana’s Carolyn Rodrigues-Birkett and Senegal’s Macky Sall. They are competing to succeed António Guterres, who steps down at the end of this year. Under the UN’s arcane selection process, the 15-member Security Council will hold multiple rounds of anonymous votes until one candidate secures at least nine votes and avoids a veto from any of the five permanent members. The chosen name then goes to the General Assembly for formal appointment, with the new Secretary-General taking office on 1 January 2027.

The contest comes at a strained moment for the world body. The United States under President Donald Trump has sharply criticised the UN for what it calls inefficient spending and a drift away from its core peace-and-security mission, while other member states insist that human rights and development remain equally central. The organisation is also grappling with a financial crisis that has deepened the urgency for reform.

Why the UN Race Is So Cautious—and What the Veto Powers Want

Unlike the lively 2016 campaign that propelled Guterres to the top, this year’s race is unusually subdued. Analysts and diplomats point to a single overriding factor: the candidates are treading carefully to avoid antagonising the veto-wielding powers, particularly the Trump administration.

The US Factor and the Push for a ‘Results-Focused’ UN

Washington’s demands for a leaner, more security-focused UN have put the candidates in a bind. While each has endorsed internal reforms and a more active Secretary-General in peace efforts, none has publicly challenged the US position—a sharp contrast to the openly contested visions of previous races. Richard Gowan of the International Crisis Group told AFP that 'everyone agrees the race is vitally important for the UN’s future, but the process has been quite cautious,' adding that contenders are wary of offending Washington and other permanent members. This dynamic has dampened the public debate and may push the Security Council towards a consensus candidate who can navigate great-power tensions.

Geography vs. Gender: A Latin American Woman—or a Compromise?

Latin America is claiming the post on geographical rotation grounds, and many member states also argue the time has come for a woman to lead the UN. Five of the six candidates are from the region (with Senegal’s Macky Sall the sole African), and four are women. Yet the lack of a clear favourite and the possibility of a late-entry compromise candidate mean neither claim is guaranteed. Grossi, the Argentine head of the International Atomic Energy Agency, is seen as the most frequently cited frontrunner, but Gowan said his victory is far from assured. Grynspan and Rodrigues-Birkett are also said to have significant backing. The quiet campaign leaves room for a surprise name to emerge if the Council deadlocks.

Timeline and What Comes Next in the UN Leadership Selection

For governments, multilateral organisations and businesses that work with the UN system, several signposts matter:

  • 30 July informal vote: The first secret ballot in the Security Council will offer an early signal of how many candidates advance, though the results are not made public. Leaks often reveal frontrunners.
  • Consensus and veto dynamics: Watch whether any permanent member casts a ‘discouragement’ vote (a softer form of veto). A clear US or Chinese reservation could reshape the field.
  • Reform agenda: The candidates’ detailed reform proposals—on financing, peacekeeping and management—will become more concrete as the process advances. Their positions could affect UN procurement, development funding and the operating environment for contractors.
  • Timing of appointment: While the new SG takes office in January 2027, the formal appointment by the General Assembly is expected in the autumn. The identity of the next Secretary-General will set the tone for UN engagement with the private sector and the trajectory of the financial crisis.
