António Manuel de Oliveira Guterres (born 30 April 1949) is a Portuguese politician and diplomat best known for serving as Secretary-General of the United Nations since 2017. Before assuming that global post he led Portugal's government as Prime Minister and later headed the UN refugee agency. His public reputation rests on crisis management, advocacy for refugees and displaced people, and a sustained emphasis on multilateral cooperation.

Career and principal offices

Guterres's career spans national politics and international diplomacy. His principal roles include:

  • Leader of Portugal's Socialist Party and Prime Minister of Portugal (1995–2002).
  • President of the Socialist International (1999–2005), a worldwide association of social-democratic parties.
  • United Nations High Commissioner for Refugees (UNHCR) from 2005 to 2015, overseeing humanitarian response during multiple refugee crises.
  • Secretary-General of the United Nations, first appointed by the United Nations General Assembly in 2016 to take office in 2017; he succeeded Ban Ki-moon.

During his time at the UN he was reappointed for a second term that continued the organization’s focus on peacebuilding, humanitarian access and preventive diplomacy. His tenure has involved managing the Secretariat, representing the UN in diplomatic settings, and setting administrative priorities across UN agencies.

Policy priorities and initiatives

Guterres has articulated a set of recurring priorities that guide his work at the UN. These include strengthening multilateral institutions, responding to large-scale humanitarian emergencies, addressing climate change as a global security risk, and advancing human rights and gender equality. He has publicly called for increased burden-sharing among member states for refugees and for reforms to make the UN more effective and transparent.

Key themes promoted by Guterres can be grouped as:

  1. Humanitarian protection and refugee response.
  2. Climate action linked to security and development.
  3. Support for multilateral diplomacy and collective crisis management.
  4. Institutional reform, including management and accountability at the UN.

These priorities reflect both his earlier work with displaced populations at the refugee agency and his political background in social-democratic governance.
