Portugal calls snap election for May 18 after Montenegro government falls

Portugal is heading to the polls for the third time in 39 months. President Marcelo Rebelo de Sousa announced late on Thursday that he had dissolved parliament and called a snap general election for 18 May, after Prime Minister Luis Montenegro lost a confidence vote in the Assembly of the Republic two days earlier. The decision ends a government that lasted barely a year and extends a cycle of political instability that has seen three administrations collapse since the start of 2022.

The confidence vote that brought down the government

Montenegro's Democratic Alliance coalition, a centre-right alliance led by his Social Democratic Party (PSD), commanded only a minority in the 230-seat parliament. The confidence motion was tabled by the opposition after weeks of mounting pressure over allegations that Montenegro's family law firm, Spinumviva, had received payments from companies with interests in government decisions. Montenegro denied any wrongdoing and argued the payments were for legitimate legal services rendered before he took office. He refused to resign, instead putting the matter to a vote. The motion passed with support from the Socialist Party (PS), the far-right Chega, the Left Bloc and the Communist Party, leaving Montenegro with no constitutional path but to request dissolution.

The president's announcement came after consultations with party leaders on Thursday afternoon. Under the Portuguese constitution, the president has the power to dissolve parliament and call elections, though he is required to hear the parties first. Rebelo de Sousa, a former PSD leader himself, acknowledged the "difficulties the country is facing" and urged voters to perform their civic duty. His statement carried a note of weariness: this is the second dissolution he has ordered in twelve months.

A pattern of instability

The last early election, held on 10 March 2024, was triggered by the resignation of Socialist prime minister Antonio Costa in November 2023. Costa stepped down after prosecutors named his chief of staff as a formal suspect in an influence-peddling investigation involving lithium mining and hydrogen projects. Costa himself was not accused of any crime, but he judged the political damage irreparable. The Socialists went into that election as incumbents but lost ground; the Democratic Alliance emerged as the largest force, though without a majority. Montenegro formed a minority government with informal support from the smaller Liberal Initiative party.

Before that, the January 2022 election had given Costa an unexpected absolute majority, the first for any party since 1991. That parliament was supposed to run until 2026. Instead, Portugal has now had three prime ministers, Costa, Montenegro, and whoever emerges from the May vote, in a single legislative term. The frequency of elections is without precedent in democratic Portugal. Since the Carnation Revolution of 1974, no legislature has produced three general elections in so short a span.

The Montenegro scandal

The immediate cause of the collapse was the Spinumviva affair. Investigative journalists revealed that the law firm, founded by Montenegro's wife and now run by his two sons, had signed consultancy contracts with several companies that stood to benefit from government decisions on concessions, licensing and regulation. One client was a gambling concessionaire; another was a real estate group with interests in tourism development. Montenegro insisted the contracts predated his premiership and that he had no involvement in the firm's management. He published his tax returns and declared his assets, but opposition parties argued the appearance of a conflict was sufficient to warrant his removal.

The prime minister's refusal to step down voluntarily framed the episode as a test of institutional resilience. By calling a confidence vote, Montenegro gambled that the opposition would not want to shoulder the blame for another election so soon. He miscalculated. The Socialists, polling neck-and-neck with the Democratic Alliance, saw an opportunity to return to power. Chega, the populist right-wing party that has surged to become the third force in parliament, voted against the government in the hope of capitalising on anti-establishment sentiment. The Left Bloc and Communists, traditionally reluctant to align with the right, concluded that a caretaker government was preferable to a compromised one.

What the polls suggest

Opinion surveys conducted since the confidence vote show a tightly contested race. Most pollsters place the Socialist Party and the Democratic Alliance within a point or two of each other, both hovering around 30 per cent. Chega polls between 18 and 22 per cent, the Liberal Initiative around 6 per cent, and the Left Bloc and Communists roughly 4 per cent each. If these numbers hold, neither main bloc will secure a majority, and the arithmetic of coalition-building will be fiendishly difficult. The Socialists would need support from the Left Bloc, Communists and possibly the Greens to reach 116 seats; the Democratic Alliance would need Chega and the Liberal Initiative, an alliance Montenegro has repeatedly ruled out.

The similarity to March 2024 is striking. Then, the Democratic Alliance won 28.8 per cent to the Socialists' 28.0 per cent, a margin of 0.8 percentage points that translated into a two-seat advantage. The resulting minority government survived only because the Socialists abstained on key votes rather than force another election. That patience has now evaporated. Socialist leader Pedro Nuno Santos, who took over from Costa, has signalled that his party will not prop up a centre-right minority again. The question is whether the Socialists can improve on their 2024 result enough to form a left-wing majority, or whether Portugal faces a fourth election before the decade is out.

Voter fatigue and rising abstention

Turnout in March 2024 reached 59.9 per cent, the highest since 1995, driven by a sense that the election mattered. Analysts now expect a sharp drop. Successive government collapses, each triggered by ethical controversies rather than policy disagreements, have fostered a perception that politicians are more concerned with survival than governance. A survey by the Catholic University of Portugal's polling centre in early March found that 42 per cent of respondents felt "indifferent" or "disgusted" by the political class, up from 28 per cent a year earlier. The same poll showed only 31 per cent trusted parliament, the lowest reading since the financial crisis.

Abstention tends to hurt the left more than the right in Portugal, because Socialist voters are younger and less habitual in their turnout. If participation falls below 55 per cent, the Democratic Alliance could win a larger seat share even with a similar vote percentage. The president's appeal to civic duty may not be enough to counteract the fatigue. Portugal's electoral law does not allow postal voting for domestic residents, and early voting is limited to a single day a week before the election, which may further depress turnout among mobile workers and students.

European implications

Portugal's instability matters beyond its borders. As a member of the euro area and a current net recipient of EU cohesion funds, Lisbon's ability to absorb and execute the Recovery and Resilience Plan (RRP), 16.6 billion euros in grants and loans under the NextGenerationEU programme, depends on administrative continuity. The caretaker government can only manage day-to-day affairs and urgent matters; it cannot submit new legislation or approve major procurement. Delays in RRP implementation risk missing the August 2026 deadline for fund disbursement. The European Commission's country reports have repeatedly flagged Portugal's administrative capacity as a bottleneck; political churn exacerbates it.

There is also the question of Portugal's voice in the Council of the EU. With the European Council set to debate the next multiannual financial framework, defence spending and enlargement in the coming months, a caretaker prime minister lacks the mandate to negotiate hard. Montenegro attended the March European Council as a lame duck; his successor, if one emerges quickly, will have had barely weeks to prepare for the June summit. Portugal's traditional role as a bridge between northern and southern member states on fiscal rules is harder to play when the government changes annually.
