Portugal's government: why its parliament keeps being dissolved

What the Carnation Revolution wrote into law

The system Portugal governs itself by is younger than most of the people living under it. A dictatorship held power from the late 1920s until 25 April 1974, when several hundred army officers, alienated by thirteen years of colonial war in Africa, removed it in a coup that met almost no resistance and became known as the Revolution of the Carnations.

What followed was not a straight line to a settlement. The transition ran through a moderate opening from May 1974 to March 1975, a radical phase through most of 1975 in which the direction of the state was genuinely uncertain, and a moderate reaction from late that year to the middle of 1976. Censorship, the political police and the paramilitary forces were abolished early. The African colonies became independent through the same period, and Portugal received several hundred thousand returning settlers within a year.

The constitution adopted in 1976 was written at the end of that sequence and it carries the marks of it. It committed the state to a transition to socialism, entrenched extensive social rights, and gave the armed forces a supervisory body over the civilian institutions. Successive revisions removed the military tutelage and the economic programme while leaving the rights and the structure in place, and the document has been amended repeatedly since without being replaced.

Why the president is called a moderating power

Portugal is a semi-presidential republic and its own constitutional literature describes the presidency as a fourth thing rather than as part of the executive. Portugal's head of state is directly elected, holds no departmental portfolio and does not chair the cabinet, and the powers the office does hold sit across the other branches rather than inside one of them.

The instruments are specific. The president appoints the prime minister, having regard to the election result rather than being bound by it; can refuse to promulgate a law and return it to parliament; can refer legislation to the Constitutional Court before signing it; and can dissolve the Assembly of the Republic and call an early election.

The dissolution power is the one that shapes Portuguese politics most, because it has been used repeatedly rather than held in reserve. Parliament was dissolved and early elections called in 2004, in 2011 after the government resigned during the debt crisis, in 2023 after a prime minister resigned amid a criminal investigation into government contracts, and in 2025 after a government lost a confidence vote in March.

How the Assembly of the Republic works

Legislative power sits primarily with a single chamber of 230 members. There is no upper house, which makes Portugal unusual among the larger European democracies and removes a check that most comparable systems rely on.

Two features are worth separating out. The government itself may legislate on certain matters by decree-law, so not everything with the force of law passes through the chamber. And Portuguese emigrants vote in their own constituencies, which reflects a diaspora large relative to the resident population and has occasionally delayed the formation of a government while overseas ballots were counted or rerun.

Why governments so often end early

A Portuguese government can be brought down by parliament, can resign on its own, and can be dismissed by the electorate when the president dissolves the chamber. All three routes have been used inside two decades.

Minority government is the normal condition. Parties that fall short of 116 seats govern with the tolerated support of others, and the arrangement is negotiated as a set of parliamentary agreements rather than as a coalition with shared ministries. That produces governments that can legislate but cannot rely on surviving a single bad vote, and it explains why the average completed term is shorter than the constitutional four years.

The budget is the recurring pressure point. A minority government has to assemble a majority for its annual budget from parties holding no ministerial responsibility for the result, and a budget defeated in the chamber is treated as a confidence question in practice whether or not it is one in form. Several of the early dissolutions listed above began as budget arithmetic that could not be made to work.

The pattern was clearest after the election of 2015. The largest bloc was invited to form a government and was defeated in parliament within weeks, producing the shortest-lived national government since 1974. A minority administration then took office with the support of parties to its left that held no ministries, and it lasted a full term.

What the end of empire cost the state

The end of empire arrived faster in Portugal than in any comparable case, and the administrative consequence is underrated.

Between 1974 and 1976 Portugal lost every African territory it held and received several hundred thousand people returning from them, into a country of under ten million that was simultaneously replacing its entire system of government. The returnees, known as the retornados, arrived without housing, employment or established political attachment, and absorbing them fell to institutions that had existed for months.

The state that emerged was shaped by having to do all of it at once. Large parts of the economy had been nationalised during the radical phase of 1975 and were reprivatised over the following two decades; the civil service inherited from the dictatorship was retained rather than rebuilt, on the reasoning that a country cannot run without one; and the constitutional order was written while the outcome was still contested rather than after it had settled.

That sequence explains a feature visitors and analysts both notice: Portuguese democratic institutions are young, the administrative culture beneath them is much older, and the two do not always move at the same speed.

Who checks the constitution here

The judiciary is independent of both political branches and is organised in parallel hierarchies rather than a single pyramid.

Ordinary civil and criminal law runs up to a Supreme Court of Justice. Administrative and tax law runs up to a separate Supreme Administrative Court. A Constitutional Court sits outside both and rules on whether legislation conforms to the constitution, and a Court of Auditors examines public spending and can refuse to register a contract it considers unlawful, which is a power with real bite over public procurement.

The Constitutional Court also carries a specific historical function. Because the 1976 text entrenched an unusually wide catalogue of social and economic rights, the court has repeatedly had to rule on whether austerity measures reducing pensions, public sector pay or benefits breach them. During the years following the 2011 assistance programme it struck down several such measures, which meant that the limits of the adjustment were set in part by a court rather than entirely by the negotiation with the lenders.

The distinctive feature is when the constitutional review happens. The president may refer a bill to the Constitutional Court before signing it, so a question about constitutionality can be settled while the text is still a proposal. Review after enactment is also available. The combination gives the court a role in the legislative process itself rather than only in cleaning up after it.

How the Azores and Madeira govern themselves

Two Atlantic archipelagos hold autonomy written into the constitution rather than granted by ordinary legislation, and they are the only parts of the country that do.

Madeira has operated under an autonomy statute in effect since 1976 and the Azores under one promulgated in 1980. Each has its own regional government and legislative assembly with competence over matters the constitution reserves to them, and each sends members to the national parliament as well.

The rest of the country is administered through 18 districts, each headed by a governor appointed by the minister responsible for internal administration. The constitution provides for further administrative decentralisation and calls for a future reorganisation on a regional basis, which has been proposed and deferred repeatedly since 1976 and has never been carried through.

How the party system changed after the bailout

From 1975 the system was dominated by two parties, one centre-left and one liberal-conservative, which between them supplied every prime minister and most of the parliamentary weight. Smaller parties on the left, a communist party and a left bloc among them, held enough seats to matter in a minority arithmetic without entering government.

The 2010 sovereign debt crisis broke the pattern's stability without immediately breaking the pattern. Portugal requested assistance from the International Monetary Fund and the European Union in 2011, the government that requested it resigned, and the austerity programme that followed was administered by its successor and then rejected at the polls.

The clearer break came later. In the snap election of 2025 a nationalist party of the far right took 23% of the vote and 60 of the 230 seats and became the official opposition, ending fifty years in which the two established parties had held that position between them. The governing coalition that emerged from the same election held a stronger mandate than before and still fell short of a majority.

Where Portugal stands abroad

Portugal is a founding member of NATO, joined what is now the European Union in 1986 alongside Spain, and adopted the euro at its introduction. It is in the Schengen area, the OECD, the Council of Europe and the World Trade Organization.

Two further relationships have no equivalent elsewhere in Europe. The Community of Portuguese Language Countries links Portugal to Brazil, Angola, Mozambique and five smaller states across four continents, and it is a diplomatic asset out of proportion to Portugal's size. And the alliance with England, dating from the fourteenth century, is the oldest continuously active alliance between any two states.

The last colonial obligation closed in December 1999, when Macau reverted to Chinese sovereignty, a quarter of a century after the African territories became independent.

European membership since 1986 has been the single largest external influence on Portuguese governance. Structural funds paid for the motorway network, the universities and much of the municipal infrastructure; the single market reoriented trade away from the former colonies and towards the rest of Europe; and the euro removed the exchange rate that had absorbed Portuguese competitiveness problems for decades, which is a substantial part of why the debt crisis of 2010 fell as hard as it did.

The relationship with Spain sits underneath all of it and is rarely stated. Portugal shares a single land border, 1,214 kilometres of it, with a country five times its size and speaking a closely related language, and the whole of Portuguese foreign policy since the twelfth century has been organised around not being absorbed by it. The English alliance, the Atlantic orientation, the empire and the enthusiasm for European institutions are all, in part, answers to the same question.
