The next Castilian-Leonese regional election will be held no later than Saturday, 21 March 2026, to elect the 12th Cortes of the autonomous community of Castile and León. All 81 seats in the Cortes will be up for election. The electoral calendar of Castile and León was altered as a result of the 2022 snap election, meaning the election will be held in a date different from that of the regularly scheduled May regional and elections in 2023.
In smaller constituencies, the use of the electoral method results in an effective threshold based on the district magnitude and the distribution of votes among candidacies.[5]
Election date
The term of the Cortes of Castile and León expires four years after the date of their previous election, unless they are dissolved earlier. The election decree shall be issued no later than the twenty-fifth day prior to the date of expiry of parliament and published on the following day in the Official Gazette of Castile and León (BOCYL), with election day taking place between the fifty-fourth and sixtieth days from publication. The previous election was held on 13 February 2022, which means that the legislature's term will expire on 13 February 2026. The election decree shall be published in the BOCYL no later than 20 January 2026, with the election taking place up to the sixtieth day from publication, setting the latest possible election date for the Cortes on Saturday, 21 March 2026.[1][4][6]
The president has the prerogative to dissolve the Cortes of Castile and León and call a snap election, provided that no motion of no confidence is in process and that dissolution does not occur either during the first legislative session or before one year has elapsed since a previous dissolution. In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the Cortes shall be automatically dissolved and a fresh election called.[1]
Parliamentary composition
The table below shows the composition of the parliamentary groups in the Cortes at the present time.[7]
The electoral law allows for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates. Parties and federations intending to form a coalition ahead of an election are required to inform the relevant Electoral Commission within ten 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 of candidates.[4][6]
Below is a list of the main parties and electoral alliances which will likely contest the election:
The table below lists voting intention estimates 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. When available, seat projections determined by the polling organisations are displayed below (or in place of) the percentages in a smaller font; 41 seats are required for an absolute majority in the Cortes of Castile and León.
^UPL does not field candidates outside of León (13 seats), Salamanca (10 seats) and Zamora (7 seats) and therefore cannot obtain a majority in parliament.
^XAV does not field candidates outside of Ávila (7 seats) and Valladolid (15 seats) and therefore cannot obtain a majority in parliament.
