António José Martins Seguro (born March 11, 1962, in Penamacor) is a lawyer, political scientist, and the current President of the Portuguese Republic, inaugurated on March 9, 2026 after winning the two-round presidential election in January–February 2026.

Career: 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 a 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 and won the presidency in February 2026.

Political philosophy: Seguro positions himself as representing a "modern and moderate" left, advocating financial responsibility while opposing austerity. As President, he has emphasized institutional trust, efficient governance, and a collaborative relationship with the government while maintaining rigorous constitutional oversight.

Chega ("Enough") is a Portuguese far-right populist party founded in 2019 by André Ventura. It positions itself as an anti-establishment movement against what it calls a "rotten and corrupt system" of PS-PSD dominance. The party surged from 1.3% in 2019 to 22.8% in May 2025, becoming parliament's second-largest force with 60 seats. ​ Chega's core platform emphasizes strict immigration control—ending automatic CPLP residency, deporting non-independent immigrants, implementing job-market quotas, and requiring five-year social security contributions before benefit access. It advocates radical constitutional reform, including reducing parliament to 100 members, abolishing the prime minister position for a presidential system, and dismantling public healthcare. Law-and-order policies include life imprisonment and chemical castration proposals.

The party is defined by inflammatory anti-Romani rhetoric, with Ventura convicted multiple times for discrimination. Chega maintains international alignments with European far-right figures including Marine Le Pen, Santiago Abascal, and Matteo Salvini. Mainstream Portuguese parties, including Prime Minister Luís Montenegro's government, have imposed a cordon sanitaire, refusing coalition with Chega despite its parliamentary strength.
