Humberto Delgado was a central figure in Portuguese history who died under brutal circumstances, not by shooting as previously believed.

New evidence from a 2015 interview with his grandson suggests Delgado was beaten to death.

Delgado's death remains mired in controversy, with allegations that the PIDE planned to abduct him for a terror trial.

His 1958 presidential campaign challenged the Estado Novo regime and is famously remembered for his bold statement 'Obviamente demito-o'.

Despite facing election fraud and subsequent exile, Delgado is commemorated as a courageous critic of the authoritarian regime.
