With current UN Secretary-General António Guterres set to step down in 2026, who is in the running to replace him? A seven-part series reveal who might be in the running and assess their chances.
The potential candidates include Amina J. Mohammed (Nigeria), Mia Motley (Barbados), Alicia Barcena (Mexico), Maria Fernanda Espinosa (Ecuador), Rebeca Grynspan (Costa Rica) and Michelle Bachelet (Chile). These are names that have come up in conversations with UN insiders and other experts. All six would offer skills and experiences we believe would be valuable in these fast-paced, uncertain times.
- Could a UN insider take the top job? Amina J. Mohammed is the current Deputy Secretary-General of the United Nations. She has been in the role since early 2017, making her something of a veteran within senior circles.
A British-born Nigerian, Mohammed’s UN experience goes back even further. For instance, she played a critical role in the development of the post-2015 Development Agenda as an Assistant Secretary-General within previous Secretary-General Ban Ki-moon’s office.
In that role, she acted as the link for the Secretary-General and the High-Level Panel of Eminent Persons Annan set up under several global political leaders. This UN experience means Mohammed not only understands the internal workings of international relations, but has interacted with many world leaders for more than a decade.

Mohammed’s Nigerian credentials are also noteworthy. Before becoming UN Deputy Secretary-General, she served as her country’s Environment Minister, where she steered the country’s efforts on the Sustainable Development Goals and action on climate change. Her prior experience cuts across government agencies, the UN, and academia, including a spell at Columbia University in New York.
Mohammed’s time as Guterres’ deputy at the UN has seen her carve out an important role for sustainable development. She is Chair of the UN Sustainable Development Group and has attempted to reposition sustainable development and the SDGs at the center of the organization’s work.
She has also overseen reforms that give the UN Resident Coordinators—who are the most senior UN development staff at the country level—greater independence and authority to coordinate UN activities in their country. In an interview with UN News, Mohammed said these changes would allow “a much more independent and impartial leader” at the country level.
“What I would say is that, in previous times, we’ve sort of had a conductor that, through no fault of their own, is conducting a cacophony – the left-hand does not know what the right hand is doing,” she said. “Today, we have an opportunity to make a symphony for the SDGs. That’s really the difference on the ground.”
Assessing Mohammed’s Prospects
Could Amina Mohammed be the next UN Secretary-General?
While a final decision is more than two years away, here is our assessment of her advantages and disadvantages, should she choose to throw her hat into the ring.
