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.

André Ventura, born January 15, 1983, is a lawyer, academic, and Portugal's most prominent far-right leader. He founded Chega ("Enough") in 2019 after his PSD mayoral campaign attacked the Romani community. Chega surged from 1.3% in 2019 to 22.8% in May 2025, becoming parliament's second-largest party and making Ventura Leader of the Opposition.
His platform emphasizes immigration restrictions, law-and-order policies, constitutional reform, and contains inflammatory anti-Romani rhetoric that has triggered multiple discrimination convictions and investigations. Politically classified as far-right by international media, Ventura cultivates alliances with European far-right figures including Marine Le Pen and Santiago Abascal.
He announced his 2026 presidential candidacy, polling at 18% alongside independent Admiral Gouveia e Melo. His rise ended Portugal's 50-year resistance to far-right parties.
