Spain's BOE publishes Congress and Senate candidacies for 29 November election

The Boletín Oficial del Estado published the candidacies for Congress and the Senate on 28 October 2026, ahead of the general election set for 29 November. Parties, federations, coalitions and voter groups had until midnight on Monday, 26 October, to file their candidacies with the provincial electoral boards, and the BOE published them as registered.

The candidacies are not definitive yet. The electoral boards must check requirements such as the gender-alternating 'cremallera' lists and the endorsements (avales) required of parties that held no seats in either chamber at the previous general election. The boards have two days to report irregularities, and parties can correct them within 48 hours of notification. The boards then have until the following Monday to proclaim the candidacies, which will be published in the BOE on 3 November. For the first time in a general election, Congress lists must alternate women and men, a requirement introduced by Organic Law 2/2024 on parity representation, which replaced the 2023 rule of at least 40% of each sex.
