Rafael Grossi holds the strongest position in the race to succeed António Guterres as UN Secretary-General because his six years leading the International Atomic Energy Agency have given him direct visibility on nuclear non-proliferation and geopolitical flashpoints that dominate Security Council attention. Four other Latin American and Caribbean candidates—Maria Fernanda Espinosa, Rebeca Grynspan, and Michelle Bachelet—have also been formally nominated, with Espinosa entering the field only in mid-May after the April interactive dialogues, allowing her to draw on her prior General Assembly presidency and foreign-minister experience. The selection process requires a Security Council recommendation without a permanent-member veto before General Assembly approval, and the field remains open pending further diplomatic consultations and straw polls among member states.
