Istanbul, Oct 2026 : Türkiye has officially nominated former foreign minister and veteran United Nations diplomat for the post of the next UN secretary-general, state-run media reported on Saturday.
Sinirlioglu, 70, is among the candidates seeking to succeed Antonio Guterres, who is nearing the end of his second five-year term as head of the world body. The next UN chief will take charge amid growing calls for institutional reform, escalating global conflicts and a financial crisis that has forced the organisation to reduce several humanitarian and development programmes.
Türkiye’s current representative to the UN, Ahmet Yildiz, told the Anadolu news agency that Sinirlioglu’s nomination had been formally submitted with the backing of Turkish President Recep Tayyip Erdogan.
Sinirlioglu had indicated his interest in the position on the sidelines of the UN General Assembly’s high-level meeting in New York last month.
Veteran Diplomat Enters UN Leadership Race
Sinirlioglu served as Türkiye’s foreign minister for several months in 2015, during an interim period between elections. He subsequently represented the country as its ambassador to the United Nations from 2016 to 2023.
He currently serves as secretary-general of the Vienna-based Organization for Security and Cooperation in Europe (OSCE). His three-year mandate is scheduled to conclude in December 2027, while the next UN secretary-general is expected to assume office on January 1.
His nomination comes as the United Nations faces mounting criticism over its ability to respond effectively to conflicts in Iran, Ukraine and Gaza. The organisation has also come under financial pressure, with funding constraints affecting humanitarian assistance and development initiatives.
Erdogan’s Push for UN Security Council Reform
President Erdogan has repeatedly called for reforms to the UN Security Council, particularly criticising the influence of its five permanent members: the United States, Russia, China, the United Kingdom and France.
Sinirlioglu’s candidacy is expected to reflect Türkiye’s position on reforming the global organisation and making its decision-making structure more representative.
The selection of the next UN secretary-general will be determined by the 15-member Security Council. The five permanent members hold veto powers, making their support crucial to any candidate’s prospects.
The successful candidate must subsequently receive approval from the 193-member UN General Assembly.
Regional and Diplomatic Challenges
Sinirlioglu could face opposition from several quarters, including neighbouring Greece, which is currently one of the Security Council’s 10 elected members. Resistance may also emerge from Israel, a close ally of the United States.
Seven other candidates are reportedly competing to replace Guterres. Under an informal regional rotation followed in previous selections, a candidate from Latin America and the Caribbean could be considered for the position.
The race is expected to unfold amid calls for a more effective United Nations capable of addressing international conflicts, financial challenges and demands for institutional reform.
