The calling of the election

The decree is dated 5 October 2026. It says it is issued under article 115 of the Constitution and article 42.1 of Organic Law 5/1985, on the proposal of the President of the Government, after the Council of Ministers deliberated that day. It entered into force on the day it was published in the BOE, 6 October 2026 (number 248, BOE-A-2026-20742). It is signed FELIPE R. and, as President of the Government, Pedro Sánchez Pérez-Castejón.

La Moncloa published an institutional statement by the President on 5 October 2026 announcing the call. The dates and seat counts on this page are taken from the decree, not from that statement.

• Campaign: fifteen days, from midnight at the start of Friday 13 November until 24:00 on Friday 27 November (article 4).
• Constitutive sittings of the resulting chambers: 23 December, at 10:00 (article 5).
• The elections are governed by Organic Law 5/1985 and its implementing rules (article 6).

Senate

Article 3.2 of the decree, citing article 165 of the electoral law, says each provincial constituency elects four senators; the island constituencies elect three in Gran Canaria, Mallorca and Tenerife, and one in Ibiza, Formentera, Menorca, Fuerteventura, La Gomera, El Hierro, Lanzarote and La Palma. Ceuta and Melilla each elect two senators. Article 165.2 of the text read on the Board’s site, as amended by Organic Law 2/2026, lists Ibiza and Formentera separately.

Article 166 says a voter may vote for up to three candidates in provincial constituencies, two in Gran Canaria, Mallorca, Tenerife, Ceuta and Melilla, and one in the other island constituencies. The candidates with the most votes are proclaimed until the constituency’s seats are filled.

Article 165.4 says the autonomous communities also appoint one senator plus another for each million inhabitants, using the registered population at the last general election to the Senate. This page does not calculate that figure.

Gap. The current number of senators appointed by the autonomous communities is not copied here. The Senate publishes it at senado.es.

Population

Royal Decree 1117/2025 declares official the municipal-register figures at 1 January 2025. The annex, as read, does not print a national total. The 50 provincial figures plus Ceuta and Melilla in that annex add up to 49,114,494.

INE table 29005, “Cifras oficiales del padrón por municipio”, describes the series as the figures of the annual revision of the municipal register at 1 January of each year. The 2025 Total, summed by province, matches each provincial figure in that annex, and matches Ceuta and Melilla. 8,130 municipalities in the 50 provinces have a 2025 Total. Each has a page, linked from its province. Ceuta and Melilla are the city page. 6 codes in the table have an empty 2025 Total and have no page.
