Rafael Grossi’s leading position reflects his established role as IAEA Director General, where he has maintained direct engagement with the five permanent Security Council members on non-proliferation and crisis issues, a factor widely viewed as essential for securing the necessary backing in the selection process. Recent interactive dialogues held at UN Headquarters in April 2026 allowed all candidates to present their visions on reform, peacekeeping, and multilateral coordination, with Grossi emphasizing pragmatic action on institutional challenges. Rebeca Grynspan’s share draws from her UNCTAD leadership and emphasis on development priorities, while Michelle Bachelet and Macky Sall bring prior head-of-state and human rights experience that appeals to different regional and thematic constituencies. The Security Council is expected to begin formal straw polls later this year ahead of the 2027 transition.
