Under the UN Charter, the Secretary-General is appointed by the General Assembly on the recommendation of the Security Council. To choose a successor to António Guterres, whose second term ends in 2026, the Council has held a series of informal, anonymous straw polls in which members encourage or discourage each candidate.
At the sixth poll on 16 October 2026, ballots were colour-coded for the first time so that the votes of the five permanent members could be told apart. The leading candidate, Rebeca Grynspan of Costa Rica, was reported to have been discouraged by two permanent members. A seventh poll on 30 October was again reported to show no agreed candidate.
