The party's electoral success is attributed to its hardline stance against immigration and the inability of traditional parties to maintain stable governments, with this being Portugal's third election in three years.

Chega promotes national conservatism and Eurosceptic policies, often courting controversy for its rhetoric against immigrants and political elites.

Despite lacking an absolute majority, President Marcelo Rebelo de Sousa is likely to reappoint Luis Montenegro as Prime Minister, following discussions with the leaders of the main political parties.

Historically, in the March 2024 elections, Chega secured two deputies from emigrant votes, indicating a trend of differing voting patterns among emigrants compared to citizens within Portugal.

Political analysts note that the election results reflect a broader European trend of protest voting and anti-establishment sentiments, with Chega's rise mirroring similar movements across the continent.

In a significant political shift, Portugal's far-right Chega party emerged as the second largest party in parliament following snap elections held on May 18, 2025.

Chega secured 60 seats, surpassing the left-wing Socialist Party (PS), which initially appeared to have 58 seats after winning two out of four overseas constituencies.

André Ventura, the leader of Chega, asserted that the election results signify a profound transformation in the Portuguese political landscape, positioning Chega as the main opposition party.

Carlos César, the interim leader of PS, anticipated that the party would fall to third place as vote counting began, urging for unity and focus on upcoming local elections.

The PS faced an unprecedented setback, failing to elect any deputies among emigrants in Europe and beyond, marking a historic low for the party since the establishment of democracy in 1974.

Analysts suggest that Chega's presence may persist as it appeals to voters seeking radical solutions amidst the perceived failures of traditional parties.

Incoming Prime Minister Luis Montenegro is expected to lead a minority government while facing pressures from Chega to distance himself from the Socialist Party.
