From Lisbon Mayor to European Council President: The Political Odyssey of António Costa
In short: António Costa, Portugal's longest-serving prime minister of the 21st century, navigated nearly a decade of complex domestic governance before ascending to the European Council presidency. His career, marked by both significant social reforms and sudden resignation amid corruption investigations, remains a defining chapter in contemporary European political history.
Born in Lisbon in 1961 with Goan Catholic roots, António Costa entered politics early, joining the Socialist Youth at 14. His rise was steady, spanning roles from Minister of Justice to Mayor of Lisbon. In 2015, he achieved a major political feat by uniting Portugal’s left-wing parties to topple a conservative government, initiating a tenure that prioritized reversing austerity measures, increasing disposable income, and implementing social reforms like free school books and cheaper public transport.
Despite his electoral successes, including a surprise outright parliamentary majority in 2022, Costa’s third term was plagued by instability and scandals. The TAP airline severance controversy and subsequent investigations into alleged corruption regarding lithium and hydrogen projects forced his resignation in November 2023. Though he maintained his innocence, the political fallout led to the dissolution of parliament and snap elections. Notably, prosecutors later admitted to errors in the investigation, including a wiretap confusion between Costa and a cabinet minister.
In December 2024, Costa transitioned to the international stage as President of the European Council. His tenure has been defined by navigating the complexities of the Russian invasion of Ukraine and managing delicate diplomatic relations with global powers like China and India. His leadership, however, has not been without friction; reports in 2026 suggested diplomatic tensions with European leaders like Emmanuel Macron and Friedrich Merz following unauthorized outreach to Moscow, highlighting the ongoing challenges of his high-stakes role in European governance.
