Portugal election leaves centre-right minority government and surging hard right

Portugal's third general election in three years has produced another hung parliament, extending the longest period of political instability the country has experienced since the 1970s. The centre-right Democratic Alliance, led by the Social Democratic Party of incumbent Prime Minister Luís Montenegro, captured 89 seats in the 230-seat National Assembly, 27 short of an absolute majority. The hard-right populist party Chega and the centre-left Socialist Party are deadlocked on 58 seats apiece, with four seats reserved for voters abroad still to be attributed in the coming days. The result means Montenegro will return to the premiership at the head of a minority administration dependent on ad-hoc support from opposition parties, while Chega's surge confirms a structural shift in Portuguese politics that mirrors developments across western Europe.

A minority government by default

The Democratic Alliance's 89 seats represent a modest improvement on the 80 it held after the March 2024 election, but the gain is insufficient to govern comfortably. Montenegro's previous administration collapsed in March when a confidence vote was triggered by a political storm surrounding the business activities of his family law firm, Spinumviva. Opposition parties united to bring the government down, forcing an election that had not been due until 2028. Montenegro has consistently denied any wrongdoing, arguing that the firm's contracts with private companies were transparent and declared. The electorate's verdict, returning him to office but denying him a majority, suggests voters punished the opposition's timing more than they endorsed the government's record.

Formally, the next move belongs to President Marcelo Rebelo de Sousa. The president, whose role is largely ceremonial but who holds the constitutional power to appoint the prime minister, began consultations with party leaders on Monday. He is expected to invite Montenegro to form a government within days. The Democratic Alliance will then need to negotiate support on a vote-by-vote basis, most likely from the Liberal Initiative (eight seats) and potentially from the Socialist Party on specific measures. Chega has already ruled out supporting a Montenegro government, while the Socialists, now leaderless after Pedro Nuno Santos announced his resignation on election night, face an internal leadership contest that will paralyse their parliamentary strategy for weeks.

Chega's ascent and the immigration lever

The most striking feature of Sunday's result is Chega's consolidation as Portugal's third political force. The party contested its first general election in 2019, winning a single seat. Six years later it has 58 deputies and, depending on the overseas count, could claim official status as the second-largest party in parliament. Its leader, André Ventura, has built the party's appeal on three pillars: anti-corruption rhetoric, law-and-order messaging, and a hard line on immigration. The last of these has resonated most powerfully. Portugal's legal immigrant population has more than tripled in seven years, rising from fewer than 500,000 in 2018 to over 1.5 million by early 2025, according to Eurostat migration statistics. Brazilians and Asian nationals, particularly from India, Nepal and Bangladesh, account for the largest shares, drawn by labour shortages in tourism, agriculture and construction.

The speed of this demographic change has outpaced housing supply and public services in a country where the average monthly wage was €1,200 before tax in 2024, and the government-set minimum wage stands at €870. House prices and rents have risen almost continuously for a decade, accelerated by the arrival of higher-earning foreign professionals, digital nomads, retirees and tech workers, who benefit from favourable tax regimes such as the Non-Habitual Resident scheme. For many Portuguese voters, particularly in the Lisbon and Porto metropolitan areas, immigration is no longer an abstract debate but a daily experience of displacement from neighbourhoods where they grew up. Chega has been the only party to articulate that grievance without qualification, and the electoral dividend is evident.

The Socialist collapse and a leadership vacuum

If Chega's rise is the story of the right, the Socialist Party's implosion is the story of the centre-left. The party's 58 seats represent its worst result since 1987, a year when Portugal was still consolidating its democracy after the 1974 Carnation Revolution. For half a century the Socialists and Social Democrats have alternated in government, a duopoly that provided stability but also bred complacency. Corruption scandals have eroded trust in both traditional parties. The Socialist government of António Costa fell in 2023 amid a judicial investigation into lithium mining and hydrogen contracts; Costa himself resigned as prime minister. His successor, Pedro Nuno Santos, campaigned on a platform of fiscal responsibility and public investment but failed to convince voters that the party had broken with its past. His resignation on Sunday night leaves the Socialists without a leader, a clear direction, or a credible alternative to the right-wing bloc.

The leadership vacuum could not come at a worse moment. The Socialist Party's parliamentary group will need to decide whether to abstain on confidence motions, allowing a minority centre-right government to function, or to vote it down and risk a fourth election in three years. Either choice carries risks. Abstention alienates a base already drifting toward abstention or Chega; opposition risks the accusation of irresponsibility in a country where political instability is damaging investor confidence. The OECD has repeatedly flagged Portugal's political fragmentation as a drag on structural reform implementation, particularly in justice, public administration and tax administration.

Economic context: growth without convergence

Portugal's economy grew 1.9% in 2024, outpacing the euro-area average, and the budget recorded a surplus for the second consecutive year. Tourism receipts hit record levels, and exports of services, particularly technology and business services, have diversified the current account. Yet these headline figures mask a persistent convergence gap. GDP per capita remains roughly 75% of the EU average, a ratio that has barely moved in two decades. Productivity growth is anaemic. The labour market is characterised by high levels of temporary contracts and low wages, especially for young workers. The minimum wage of €870 a month, while significantly higher than a decade ago, still leaves a full-time worker below the at-risk-of-poverty threshold for a household with children. Housing costs absorb more than 40% of disposable income for renters in Lisbon, according to Statistics Portugal data.

This economic squeeze fuels the political volatility. Voters who feel the recovery has passed them by are open to radical alternatives. Chega's programme, tax cuts, pension increases, deportation of undocumented migrants, and a referendum on immigration policy, is economically incoherent by mainstream standards, but it offers a clear narrative: the system is rigged, the elites are corrupt, and only a clean break can fix it. The Democratic Alliance's campaign, by contrast, emphasised stability, European credibility and the continuation of fiscal discipline. It won the argument on competence but lost the argument on empathy.

A European pattern, a Portuguese specificity

The Portuguese result fits a continental pattern. France's National Rally, Italy's Brothers of Italy, Germany's Alternative for Germany, the Netherlands' Party for Freedom, all have moved from the fringes to the centre of political gravity in their respective countries. In each case, immigration, cultural anxiety and dissatisfaction with the management of globalisation have been the catalysts. Portugal's specificity lies in the speed of the transformation. A country that prided itself on having no parliamentary far right until 2019 now has a party with 25% of the seats. The traditional parties' duopoly, which survived the financial crisis, the troika programme and the pandemic, has fractured in barely a single electoral cycle.

There is also a geopolitical dimension. Portugal has been a consistent supporter of EU enlargement, a reliable NATO ally, and a vocal advocate for stronger EU-Africa and EU-Latin America ties. A government dependent on Chega's goodwill, or a government that adopts Chega's rhetoric to stanch the bleeding, may shift Portugal's tone in Brussels. The party is eurosceptic, though not anti-EU; it opposes further federal integration, rejects the migration pact, and has questioned sanctions on Russia. While the Democratic Alliance remains firmly pro-European, the need to negotiate every legislative act in a fragmented parliament will make Portugal a less predictable partner.

What happens next

President Marcelo Rebelo de Sousa will complete his round of consultations this week and is expected to invite Luís Montenegro to form a government by the weekend. Montenegro will then present a programme to parliament, likely in early June. The Democratic Alliance will govern on a case-by-case basis, seeking support from the Liberal Initiative on economic liberalisation measures and from the Socialists on social policy and European affairs. The four overseas seats, two from the Europe constituency and two from the rest of the world, will be counted by 28 May and could tip the balance between Chega and the Socialists for second place, a symbolic but politically charged distinction. Meanwhile, the Socialist Party must schedule a leadership congress. The names most frequently mentioned, former infrastructure minister Pedro Marques, former health minister Marta Temido, and the current parliamentary leader Eurico Brilhante Dias, represent different factions but share the challenge of rebuilding a party that has lost its identity.
