Signature

António José Martins Seguro (born 11 March 1962) is a Portuguese politician who has been the 21st President of Portugal since 2026. He is a member of the Socialist Party (PS). Seguro was Secretary General of the PS from 2011 until 2014. He was the leader of the largest opposition party in the Portuguese Parliament.

Seguro was born on 11 March 1962 in Penamacor, the third and youngest son of Domingos Sanches Seguro (1925–2017) and Maria do Céu Martins (1927–2012).^[1] He entered politics at a very young age and became a member of the Portuguese Socialist Party (PS). He studied business organization and management at the ISCTE – Lisbon University Institute, but he did not graduate. Seguro has a degree in international relations awarded later by the Autonomous University of Lisbon.

After Prime Minister José Sócrates resigned as PS General Secretary on the election night of 5 June 2011, having lost the general election by a margin higher than expected, Seguro was elected leader of the party on 23 July 2011, winning 68% of the vote against his challenger, Francisco Assis, who got 32%.^[2]

Under Seguro's leadership, the Socialist Party was able to get one of its best results ever in the 2013 local elections and won the 2014 European Parliament election in Portugal with Francisco Assis as the main candidate.

In 2014, Mayor of Lisbon António Costa beat Seguro by a landslide to be the party's nominee for prime minister. Seguro resigned from the leadership the same day, leaving Costa as Secretary-general.^[3] Seguro then retired to private life.^[4]

Seguro ran for President of Portugal in the 2026 presidential election.^[5] He advanced to the run-off election in February 2026 where he beat Chega nominee André Ventura in a landslide victory.^[6] He became the most voted candidate ever in a Portuguese election by beating Mario Soares' 1991 vote total record.^[7]

Seguro was sworn in as President on 9 March 2026, officially replacing Marcelo Rebelo de Sousa.^[8]
