On Thursday, the United Nations Security Council announced that it unanimously backed Antonio Guterres to become the organisation's next Secretary-General, and yesterday, it unanimously nominated him to the position. He will assume the office, on the 38th floor of the UN building in New York City, on January 1, next year.

His ascendance came at a time when expectations were high that the UN might elect either a woman or an Eastern European to the position, neither of which has happened before. Former New Zealand Prime Minister Helen Clark, head of the UN Development Programme, was one of 13 candidates for the job.

But it was Guterres, who was Portugal's Prime Minister from 1995 to 2002, who came out on top of a string of straw polls taken this year among General Assembly members - and there are a number of reasons he may have been the popular choice.

First and foremost is that Guterres has spent the past 10 years as the UN's High Commissioner for Refugees, one of the UN's most visible roles. The refugee crisis, and the civil war in Syria that is responsible for such a large portion of the world's refugees, are the UN's greatest concerns right now. Guterres is intimately familiar with the contours of the crisis, having managed the UN's response to it until last December.


Guterres was lauded in his crisis-management role for slashing expenditures on headquarters and staff by about half, while still maintaining, if not expanding, capacity to handle ever-growing waves of refugees.

Another reason is that Guterres is widely liked in his native Portugal, within the UN, and, most crucially, is seen as independent of undue influence by any of the Security Council's five veto-holding members: the United States, Britain, France, Russia and China.

The Russians in particular were rumoured to be holding out for an Eastern European Secretary-General.

But Martin Edwards, a professor of international relations at Seton Hall University, told the Washington Post on Thursday that "Russia decided it could live with Guterres. Arguably, they thought he's going to still try to be a mediator, not come across and say whatever [US Secretary of State] John Kerry says."

Guterres is fluent in English, French, Spanish and Portuguese.

He is a charismatic speaker who isn't afraid to call out adversaries in his speeches, even if they are in Washington or Moscow.

Given the soft-spoken demeanour of the current Secretary-General, Ban Ki Moon, Guterres promises to bring at least some more rhetorical firepower to the UN. Ban hasn't been loud, literally and figuratively, and under his tenure, the role of secretary-general has lacked the commanding moral authority that one might expect from the convener of the world's nations.

It is often said, however, that without any military backing, the UN Secretary-General is more secretary than general.

Guterres has acknowledged the organisation's lack of capacity to mediate conflict, but advocates what he calls a "diplomacy of peace". The secretary-general should "act with humility to try to create the conditions for member states that are the crucial actors in any process to be able to come together and overcome their differences", he said.

Ultimately, however, it is Guterres' experience as commissioner that made him the favoured candidate. With no end to the Syrian civil war in sight, and with the unending flow across the Mediterranean of thousands of Africans fleeing war, abject poverty and political persecution, the refugee crisis is here to stay.

"We can't deter people fleeing for their lives," he wrote in Time magazine last year.

"They will come. The choice we have is how well we manage their arrival, and how humanely."

Guterres is expected to choose a woman, and perhaps an Eastern European woman, to be his deputy. He recently said that "gender parity" is crucial to the UN as an institution.
