It is the most important role in international diplomacy. The United Nations Secretary General heads up an organisation that's in charge of keeping the peace around the world.
The role is appointed by the General Assembly - on the recommendation of the Security Council.
And for the first time in the organisation's 70 year history - candidates vying for that position will have to answer questions in open hearings.
And also for the first time - a woman could become Secretary General. Of those who have put their names forward so far, half of them are women.
But how important is the job? And how will the world’s superpowers react?
