On a bright sunny morning last November, the spectacular political career of Portuguese Prime Minister António Costa came to an abrupt halt as police officers launched a dramatic raid on his official residence in Lisbon’s Palacete de São Bento.
As investigators began to comb through the elegant neoclassical mansion overlooking the country’s parliament, authorities descended on ministries throughout the capital, the private homes of several officials, and the headquarters of the Portuguese Socialist Party.
Within hours, both Costa’s Chief of Staff Vítor Escária and his personal adviser Diogo Lacerda Machado were under arrest. Shortly thereafter, Minister of Infrastructure João Galamba and the head of the country’s environment agency, Nuno Lacasta, were indicted for suspected acts of corruption, embezzlement and influence-peddling in connection to lithium mining and hydrogen-production schemes, as well as the creation of a new state-of-the-art data center in Sines.
