Madrid will elect one more deputy in the elections on 29 November
The Madrid constituency will go from 37 to 38 seats in Congress, while Cádiz will see its representation reduced from nine to eight.
Voters in the Comunidad de Madrid will elect 38 deputies in the general elections on 29 November 2026. The allocation published this Tuesday in the Boletín Oficial del Estado adds one seat to the Madrid constituency compared to the 2023 elections.
Madrid will remain the province with the most representatives in Congress, ahead of Barcelona, which will have 32, and Valencia, with 16. Sevilla and Alicante will each elect twelve deputies. The total number of seats in the Chamber remains at 350.
The adjustment also affects Cádiz, which goes from nine to eight deputies. With this reduction, Andalucía will have 60 representatives, one fewer than before. The distribution is set out in the electoral call decree and follows the seat allocation system established in electoral legislation.
