Context & Explainers
The Assembly of the Republic (Assembleia da República) is Portugal's unicameral parliament, located in the Palácio de São Bento in Lisbon. It consists of 230 deputies elected by proportional representation for four-year terms.
The Assembly's powers include making and amending laws, approving the state budget, ratifying international treaties, and overseeing the government through debates, hearings, and committees. It can also pass votes of no confidence to bring down a government, as happened in March 2025.
Following the May 2025 elections, the current parliamentary composition is led by the Democratic Alliance (AD) with the largest share of seats, followed by Chega, PS, and smaller parties including the Liberal Initiative, Left Bloc, Livre, and PCP.
The ISP (Imposto sobre Produtos Petrolíferos e Energéticos) is Portugal's excise tax on petroleum and energy products, charged as a fixed amount per liter on petrol, diesel, and other fuels. It is one of the main components of fuel prices at the pump, alongside VAT and the carbon tax (Taxa de Carbono).
The government can adjust ISP rates — temporarily or permanently — to influence fuel prices. Rate cuts are a common policy tool to ease cost-of-living pressures on drivers and transport businesses, though they also reduce government revenue.
For consumers, the ISP is significant because even small changes in the per-liter rate translate into noticeable differences at the pump, particularly for diesel users and commercial transport operators.
