Michelle Bachelet has abandoned her bid to become the next United Nations secretary general after a third informal Security Council poll exposed the collapse of her support, leaving Costa Rican diplomat Rebeca Grynspan with the advantage in a contest now reduced to seven candidates.
The former Chilean president, who is 74, ended her campaign on Saturday with a message posted as a video on Instagram. She said: “I will now continue, with the same determination as always, my international work.”
Bachelet, a two-term president of Chile and former UN high commissioner for human rights, had presented herself as a defender of multilateralism and international law. Her withdrawal leaves the future leadership of the UN unsettled as the Security Council continues to test which candidate can command the broadest support.
A campaign built on multilateralism loses momentum
Bachelet’s candidacy gained less traction than her profile might have suggested. The former human rights chief was widely respected for her diplomatic experience, but she struggled to secure meaningful backing among members of the 15-seat Security Council. That difficulty became unmistakable in Friday’s third informal straw poll, when her support virtually disappeared.
Her campaign had argued that the UN faced sustained pressure from geopolitical rivalries, conflicting national interests and a growing disregard for international rules. Bachelet positioned herself as a guardian of the institution’s central purposes: collective diplomacy, human rights and legal restraints on the use of power.
European capitals will be watching the outcome closely. France and the United Kingdom, both permanent members of the Security Council, possess influence over the consultations that determine which name the council can recommend. Their governments, along with other European states, are likely to weigh the remaining candidates’ records on multilateral cooperation, regional security and the UN’s capacity to respond to crises.
Yet Bachelet’s exit does not produce an obvious successor. It removes one established contender, but the contest remains open, fluid and capable of changing again before the council identifies a candidate acceptable across its membership.
Grynspan moves into the leading position
The same poll that weakened Bachelet’s campaign placed Grynspan, the Costa Rican diplomat, at the front of the field. Her rise suggests that the race is consolidating around a candidate who has begun to attract the sort of cross-membership support needed to survive repeated Security Council tests.
Seven candidates remain in the competition to succeed António Guterres. More contenders may still enter, although the deadline pressure and the council’s preference for consensus mean that the field is unlikely to expand indefinitely. Each informal poll is designed to reveal divisions and encourage supporters to coalesce behind the most viable option.
Guterres is completing his second five-year term, which ends on 31 December 2026. The selection must therefore be concluded in time for the UN’s principal administrative officer to prepare for a carefully managed handover. That timetable adds urgency to the council’s deliberations, particularly if support for the leading candidate continues to grow.
Grynspan’s current advantage is not a final appointment. It is a diplomatic lead, one that could narrow if the remaining candidates unite against her or if the council discovers further reservations among its members.
How the UN’s next chief will be chosen
The Security Council will ultimately recommend a single candidate to the 193-member General Assembly. That recommendation is the decisive stage. General Assembly approval has traditionally been treated as a formality once the council reaches agreement, reflecting the assembly’s reliance on a nominee able to unite the council’s often divided membership.
The informal straw polls carry no formal vote, but diplomats attach considerable importance to them. Results expose which candidates lack sufficient support and make it harder for a nominee to claim that the council is ready to endorse them. Repeated rounds allow members to move from initial preferences toward a compromise candidate.
Consensus matters because the secretary general must operate across every region of the world while navigating the interests of the council’s five permanent members. A candidate seen as acceptable to only one bloc or geographic group is unlikely to survive the process. The successful nominee must combine diplomatic reach with the political backing needed to lead the organisation effectively.
Once the council agrees on a recommendation, the matter proceeds to the General Assembly. The assembly’s endorsement then confirms the appointment through the UN’s formal election procedure. Until that sequence is complete, however, even the candidate leading an informal poll remains under scrutiny.
Why it Matters
Bachelet’s departure reshapes the UN succession before a final choice has been made, opening a new phase in which Grynspan’s momentum will be tested against the council’s demand for consensus. The outcome will influence not only who inherits one of the world’s most visible diplomatic roles, but also how the organisation presents itself as global tensions intensify and expectations rise for decisive multilateral leadership.
