Seguro favoured to win Portuguese presidential runoff as right fails to unite behind Ventura

Portugal votes on Sunday in a presidential runoff that pits a centre-left Socialist against a far-right populist who has reshaped the country's politics in less than seven years. Antonio Jose Seguro, a former Socialist Party leader, enters the second round as the clear favourite. Final opinion polls give him roughly twice the support of Andre Ventura, the Chega party founder who finished a distant second in the first round on 18 January with 23.5% to Seguro's 31.1%.

The result will test whether Ventura's brash, anti-establishment style can translate a historic first-round breakthrough into the presidency, or whether Portugal's mainstream right will hold the line against a candidate they view as authoritarian. More than 11 million voters are eligible to cast ballots at home and abroad. Polling stations opened at 08:00 local time, with exit polls expected around 20:00.

A presidency of limited power but real consequence

The Portuguese presidency is constitutionally constrained. The head of state has no executive authority; that rests with the prime minister and cabinet. But the office carries tools that matter. The president can veto legislation passed by parliament, though parliament can override the veto with an absolute majority. More dramatically, the president holds what Portuguese political jargon calls the "atomic bomb": the power to dissolve parliament and call early elections. Marcelo Rebelo de Sousa, the outgoing centre-right president who steps down in March after two five-year terms, used that power in 2024 and again in 2025, triggering the country's third general election in three years.

Ventura has said that if elected he would seek constitutional changes to expand the president's powers and would act as a more "interventionist" head of state. Seguro, by contrast, has positioned himself as a moderate who will cooperate with the centre-right minority government led by Prime Minister Luis Montenegro. The difference in temperament is stark: where Ventura promises confrontation, Seguro promises stability.

The right's failure to coalesce

Ventura's path to victory always required consolidating the right behind him. It has not happened. Anibal Cavaco Silva, the former president who served two terms from 2006 to 2016, broke with tradition to endorse Seguro, warning of Ventura's authoritarian tendencies. Several ministers in Montenegro's government have done the same. Most of the first-round candidates who fell short have also backed the Socialist. Montenegro himself has stayed neutral, declining to endorse either man.

That fragmentation is remarkable given Ventura's first-round performance. Winning nearly a quarter of the vote as a candidate from a party founded in 2019 represents a political earthquake. But the earthquake has not remapped the landscape. The conservative establishment has decided that Ventura is a bridge too far, even at the cost of supporting a Socialist.

Chega's rapid ascent

Ventura founded Chega (Enough) in 2019 after a career as a television sports commentator and a brief stint as a Social Democratic Party councillor in Loures. The party's rise has been meteoric. In the May 2025 general election, the third in three years, Chega became the second-largest force in parliament, behind only the Socialists. That result cemented Ventura's status as the leader of Portugal's most significant far-right movement since the return to democracy in 1974.

The party's growth mirrors a broader European shift. Across the continent, populist right-wing forces have entered governments or forced policy concessions from mainstream parties. In Portugal, Chega's influence has already pulled the political centre rightward on immigration, even before Ventura reached the presidential runoff. The question now is whether the presidential election represents a ceiling or a stepping stone.

Immigration as the campaign's centrepiece

Ventura's campaign has been defined by a single issue. Foreign workers have become far more visible in Portugal in recent years, particularly in agriculture, construction and hospitality. Ventura has made that visibility the core of his message. Billboards nationwide carried slogans such as "This isn't Bangladesh" and "Immigrants shouldn't be allowed to live on welfare." The rhetoric is deliberate, theatrical and designed to dominate coverage.

Seguro has refused to match that tone. He has acknowledged pressures on housing and public services but framed them as management challenges, not civilisational threats. The contrast has allowed Seguro to occupy the space of the responsible moderate, but it has also left him open to the charge that he underestimates voter anxiety. Whether that anxiety translates into votes for Ventura on Sunday is the election's central uncertainty.

A country in search of stability

Portugal's political instability is not abstract. Three general elections in three years have left governments unable to complete full terms. The May 2025 election produced a centre-right minority administration dependent on ad hoc parliamentary support. The next president will inherit a fragmented parliament and a governing coalition that could collapse at any moment. Steadying the ship, as one Lisbon analyst put it, is the single most important task facing the winner.

That task favours Seguro. His pitch is explicitly institutional: a president who mediates, who uses the veto sparingly, who does not threaten dissolution unless absolutely necessary. Ventura's pitch is the opposite: a president who intervenes, who challenges, who uses the office as a platform for permanent campaign. Portuguese voters have historically preferred the former. Whether they still do will be clear by Sunday night.

The European context

Portugal's runoff arrives at a moment when far-right parties are in government in Italy, the Netherlands and Finland, and polling strongly in France, Germany and Austria. The European Parliament's 2024 elections delivered the strongest showing yet for nationalist and populist groups. Chega is part of that wave, but Portugal's party system has proven more resistant than some. The Social Democrats and Socialists still dominate the centre, and the Communist Party retains a structural base in the Alentejo. Ventura's failure to unite the right suggests that resistance remains real.

At the same time, Chega's parliamentary weight means it cannot be ignored. The next government, whenever it forms, will have to reckon with Ventura's deputies. Immigration policy has already hardened. The question is whether the presidency becomes another arena for that confrontation or remains a refuge from it.

The runoff is also a test of Portugal's democratic antibodies. The country's transition from dictatorship to democracy in 1974 was negotiated, not revolutionary. Its institutions were designed to prevent the concentration of power. Ventura's explicit desire to rewrite those rules puts him at odds with the consensus that has held for half a century. That consensus has frayed, three elections in three years is evidence enough, but it has not broken. Sunday will show whether it can hold one more time.

For the European Union, the result matters at the margin. Portugal has been a reliable, if quiet, member state. A president who seeks to amplify nationalist rhetoric from Belém Palace would complicate Lisbon's relationship with Brussels, particularly on migration and rule-of-law questions. Seguro offers continuity. Ventura offers disruption. The polls suggest Portuguese voters prefer the former, but the polling industry has been wrong before. The ballot boxes will have the final say.
