Next Cantabrian regional election

The Parliament of Cantabria is the devolved, unicameral legislature of the autonomous community of Cantabria, having legislative power in regional matters as defined by the Spanish Constitution and the Cantabrian Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president.[1] Voting for the Parliament is on the basis of universal suffrage, which comprises all nationals over 18 years of age, registered in Cantabria and in full enjoyment of their political rights.

The 35 members of the Parliament of Cantabria are elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of five percent of valid votes—which includes blank ballots—being applied regionally.[1][2]

The term of the Parliament of Cantabria expires four years after the date of its previous election. Elections to the Parliament are fixed for the fourth Sunday of May every four years. The previous election was held on 28 May 2023, setting the election date for the Parliament on Sunday, 23 May 2027.[1][2][3]

The president has the prerogative to dissolve the Parliament of Cantabria and call a snap election, provided that no motion of no confidence is in process, no nationwide election is due and some time requirements are met: namely, that dissolution does not occur either during the first legislative session or within the legislature's last year ahead of its scheduled expiry, nor 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 Parliament is to be automatically dissolved and a fresh election called. Any snap election held as a result of these circumstances will not alter the period to the next ordinary election, with elected deputies merely serving out what remains of their four-year terms.[1]

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; 18 seats are required for an absolute majority in the Parliament of Cantabria.
