UNITED NATIONS, Sept 29 (Reuters) – An informal poll by the United Nations Security Council on ​Tuesday placed former Costa Rican Vice President ‌Rebeca Grynspan as the frontrunner in the contest to become the 10th UN secretary-general, sources close to the process said.

The fourth secret poll by the 15-member ‌Security ​Council followed the gathering ⁠of world leaders at ⁠the General Assembly in New York last week. The first and third polls, held in July and September, also showed Grynspan narrowly ​ahead while an August poll placed Guyana’s U.N. Ambassador Carolyn Rodrigues-Birkett in the top ⁠spot.

After former Chilean President ⁠Michelle Bachelet dropped out of the ​race this month, seven candidates are vying to ​succeed Antonio Guterres. The former Portuguese prime ‌minister steps down at the end of this year after two five-year terms. It is still possible for more candidates to enter ⁠the race.

Ultimately the five Security Council veto powers  —  the United States, China, Russia, France and Britain  — need to agree ⁠on a ‌candidate. When Guterres was chosen ⁠in 2016, it took six straw ​polls ‌for the Security Council to reach ​agreement.

The UN ⁠Security Council will eventually formally recommend a candidate to the 193-member General Assembly for election. Approval by the assembly has long been seen as a rubber stamp.
