Background:
António José Martins Seguro (born March 11, 1962, in Penamacor) is a lawyer, political scientist, and Socialist Party politician running for president in Portugal's January 18, 2026 election. He led Socialist Youth (1990-1994), served as MEP (1999-2001), was Minister Adjunct to PM António Guterres (2001-2002), and led the PS parliamentary group (2004-2005). Elected PS Secretary-General in 2011 with 68%, he led the opposition during Portugal's bailout era. In 2014, António Costa defeated him in party primaries by a landslide, prompting Seguro's resignation and decade-long retreat from politics. He returned in 2025, launching the movement UPortugal and announcing his presidential candidacy in June. He received official PS backing in October 2025. Political Philosophy:
Seguro positions himself as representing a "modern and moderate" left, offering a progressive alternative to conservative candidates. He advocates for "financial responsibility but critical of austerity," attempting to reposition the PS at center-left. His campaign emphasizes institutional trust, efficient governance, and hope for a better future.
