The possibility of a rebellion by PSD deputies against an agreement with Chega for the election of Constitutional Court judges is considered unlikely, as the voting system requires a joint list where failing to elect the Chega-nominated candidate would also block the election of the PSD's own nominees. The vote, scheduled for April 16, requires a two-thirds majority, and despite internal resistance within the PSD towards André Ventura's party, the pragmatic need to secure their own seats is expected to maintain party discipline. Meanwhile, the PS remains divided on how to respond, with some members advocating for a break from negotiations due to the PSD's preference for Chega as a partner.

Context & Explainers
The Assembly of the Republic (Assembleia da República) is Portugal's unicameral parliament, located in the Palácio de São Bento in Lisbon. It consists of 230 deputies elected by proportional representation for four-year terms.
The Assembly's powers include making and amending laws, approving the state budget, ratifying international treaties, and overseeing the government through debates, hearings, and committees. It can also pass votes of no confidence to bring down a government, as happened in March 2025.
Following the May 2025 elections, the current parliamentary composition is led by the Democratic Alliance (AD) with the largest share of seats, followed by Chega, PS, and smaller parties including the Liberal Initiative, Left Bloc, Livre, and PCP.
The Constitutional Court (Tribunal Constitucional) is Portugal's highest court for constitutional review. Its primary role is to assess whether laws, decrees, and government actions comply with the Portuguese Constitution, and it has the power to strike down or suspend unconstitutional measures.
The court consists of 13 judges — 10 appointed by the Assembly of the Republic and 3 co-opted by the other judges. It also oversees the legality of political parties and their finances, verifies election results, and rules on the constitutionality of referendums.
The Constitutional Court is frequently in the news when opposition parties, the President, or the Ombudsman refer controversial legislation for review — such as labor reforms, housing laws, or immigration policy changes. Its rulings are final and binding.
The Social Democratic Party ('Partido Social Democrata' or 'PSD') is a liberal-conservative political party in Portugal that is the leading partner of the The Democratic Alliance (AD) which is the country's ruling party, with Prime Minister Luís Montenegro.
The Social Democratic Party, despite its name, occupies the centre-right of Portugal's political spectrum. Luís Montenegro, who became Prime Minister in April 2024, leads Portugal's current minority government. The PSD has been one of Portugal's two dominant parties since 1974, having formed nine governments including four with absolute majorities. Montenegro, a former party leader from 1996-1999, was elected with the highest approval rating among party leaders at 10.7 points out of 20.
The Democratic Alliance is a centre-right coalition that includes the smaller CDS – People's Party, a Christian democratic party that has historically been the PSD's coalition partner. Together, they govern without a parliamentary majority, requiring case-by-case support from opposition parties to pass legislation.
Chega ("Enough") is a Portuguese far-right populist party founded in 2019 by André Ventura. It positions itself as an anti-establishment movement against what it calls a "rotten and corrupt system" of PS-PSD dominance. The party surged from 1.3% in 2019 to 22.8% in May 2025, becoming parliament's second-largest force with 60 seats. Chega's core platform emphasizes strict immigration control—ending automatic CPLP residency, deporting non-independent immigrants, implementing job-market quotas, and requiring five-year social security contributions before benefit access. It advocates radical constitutional reform, including reducing parliament to 100 members, abolishing the prime minister position for a presidential system, and dismantling public healthcare. Law-and-order policies include life imprisonment and chemical castration proposals.
The party is defined by inflammatory anti-Romani rhetoric, with Ventura convicted multiple times for discrimination. Chega maintains international alignments with European far-right figures including Marine Le Pen, Santiago Abascal, and Matteo Salvini. Mainstream Portuguese parties, including Prime Minister Luís Montenegro's government, have imposed a cordon sanitaire, refusing coalition with Chega despite its parliamentary strength.
