UN secretary-general race: What it takes to be the world’s top diplomat

The United Nations is set to elect a new secretary-general to replace Antonio Guterres, who will complete his second five-year term on December 31. The role, defined by the UN Charter as the 'chief administrative officer,' has historically been filled by candidates from non-global powers, with the secretary-general mediating conflicts and advising the Security Council. The UN faces challenges to its authority amid renewed criticism from the US and Israel.
