The PSP (Polícia de Segurança Pública) is Portugal's national civilian police force, founded in 1867. Responsible for defending Republican democracy and safeguarding internal security and citizens' rights, the PSP polices major cities—Lisbon, Porto, Faro—and large urban areas, covering only 4% of Portugal's territory but roughly half the population. Led by a National Director under the Ministry of Internal Affairs, its approximately 21,500 officers handle preventive policing, crime investigation, public order, airport security, diplomatic protection, private security regulation, firearms licensing, and border control (since 2023).​

PSP vs. GNR: The PSP is civilian with police-focused training and urban jurisdiction, while the GNR (Guarda Nacional Republicana) is military (gendarmerie) with military training, covering 96% of Portugal's rural and suburban territory. Both share core public safety missions but differ fundamentally in nature, training, and geographic responsibility.

Minimum services (serviços mínimos) are the legally required basic services that must be maintained during a strike to protect public safety—in healthcare this typically covers emergency care, critical ambulance coverage and intensive care. They matter because the INEM workers' committee admitted that late or unclear communication about which teams would be available during the end-of-2024 strike may have reduced operational capacity and confused patients; as an expat, expect limited non-urgent care during strikes and check official updates or call 112 for true emergencies.

Mário José Gomes de Freitas Centeno (born 1966) is Portugal's central bank governor and one of the country's most internationally recognized economic figures. As Finance Minister under António Costa's first PS government, he became known as "Cristiano Ronaldo of European finance" for turning Portugal's deficit into a surplus while reversing austerity.

He was elected president of the Eurogroup (the informal body of euro area finance ministers) in 2018 — the first Portuguese to hold the role. Since becoming Governor of Banco de Portugal in 2020, he sits on the ECB's Governing Council and oversees Portuguese banking supervision and financial stability.
