Overview
Under the 1979 Statute of Autonomy, the Basque Parliament is the unicameral legislature of the Basque Autonomous Community, having legislative power in devolved matters, as well as the ability to grant or withdraw confidence from a lehendakari.[1] The electoral and procedural rules are supplemented by national law provisions.[2]
Date
The term of the Basque Parliament expires four years after the date of its previous election, unless it is dissolved earlier. The election decree shall be issued no later than 25 days before the scheduled expiration date of parliament and published on the following day in the Official Gazette of the Basque Country (BOPV), with election day taking place 54 days after the decree's publication.[3] The previous election was held on 21 April 2024, which means that the chamber's term will expire on 21 April 2028. The election decree shall be published in the BOPV no later than 28 March 2028, setting the latest possible date for election day on 21 May 2028.
The lehendakari has the prerogative to dissolve the Basque Parliament at any given time and call a snap election, provided that no motion of no confidence is in process.[4] In the event of an investiture process failing to elect a lehendakari within a 60-day period from the Parliament's reconvening, the chamber is to be automatically dissolved and a fresh election called.[5]
Electoral system
Voting for the Parliament is based on universal suffrage, comprising all Spanish nationals over 18 years of age, registered in the Basque Country and with full political rights, provided that they have not been deprived of the right to vote by a final sentence.[6]
The Basque Parliament has 75 seats. All are elected in three multi-member constituencies—corresponding to the provinces of Álava, Biscay and Gipuzkoa, each of which is assigned a fixed number of 25 seats to provide for an equal parliamentary representation of the three provinces—using the D'Hondt method and closed-list proportional voting, with a three percent-threshold of valid votes (including blank ballots) in each constituency.[7] The use of this electoral method may result in a higher effective threshold depending on district magnitude and vote distribution.[8]
The law does not provide for by-elections to fill vacant seats; instead, any vacancies arising after the proclamation of candidates and during the legislative term will be filled by the next candidates on the party lists or, when required, by designated substitutes.[9]
Current parliament
The table below shows the composition of the parliamentary groups in the chamber at the present time.[10][11]

Parties and candidates
The electoral law allows for parties and federations registered in the interior ministry, alliances and groupings of electors to present lists of candidates. Parties and federations intending to form an alliance are required to inform the relevant electoral commission within 10 days of the election call, whereas groupings of electors need to secure the signature of at least one percent of the electorate in the constituencies for which they seek election, disallowing electors from signing for more than one list.[12] Amendments in 2024 required a balanced composition of men and women in the electoral lists through the use of a zipper system.[13]

Opinion polls
The tables below list opinion polling results in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" column on the right shows the percentage-point difference between the parties with the highest percentages in a poll.
Voting intention estimates
The table below lists weighted voting intention estimates. Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between polling organisations. When available, seat projections determined by the polling organisations are displayed below (or in place of) the percentages in a smaller font; 38 seats are required for an absolute majority in the Basque Parliament.
