The 2015 Asturian regional election was held on Sunday, 24 May 2015, to elect the 10th General Junta of the Principality of Asturias. All 45 seats in the General Junta were up for election. Because regional elections in the Principality of Asturias were mandated for the fourth Sunday of May every four years, the 2012 snap election did not alter the term of the four-year legislature starting in 2011. The election was held simultaneously with regional elections in twelve other autonomous communities and local elections all throughout Spain.

Final results showed the Spanish Socialist Workers' Party (PSOE) with 26.5% of the vote (14 seats), the People's Party (PP) in second with 21.6% (11 seats) and newly created Podemos (Spanish for "We can") in a close third with 19.1% (9 seats). The Asturias Forum (FAC), which had ruled the community in the 2011–12 period, saw a dramatic loss of support, falling to fifth place with 8.2% and 3 seats, overcame by a stagnant United Left (IU/IX) and in a draw with up-and-coming Citizens (C's).

Socialist leader Javier Fernández was able to retain the regional government thanks to the support of United Left, after PP and FAC joined their votes against the PSOE and with Podemos supporting its own candidate.

Overview

Electoral system

The General Junta of the Principality of Asturias was the devolved, unicameral legislature of the autonomous community of Asturias, having legislative power in regional matters as defined by the Spanish Constitution and the Asturian Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president.

Voting for the General Junta was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Asturias and in full enjoyment of their political rights. Additionally, Asturians abroad were required to apply for voting before being permitted to vote, a system known as "begged" or expat vote (). The 45 members of the General Junta of the Principality of Asturias were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency. Seats were allocated to constituencies, which were established as follows:

Central District, comprising the municipalities of Aller, Avilés, Bimenes, Carreño, Caso, Castrillón, Corvera de Asturias, Gijón, Gozón, Illas, Las Regueras, Langreo, Laviana, Lena, Llanera, Mieres, Morcín, Noreña, Oviedo, Proaza, Quirós, Ribera de Arriba, Riosa, San Martín del Rey Aurelio, Santo Adriano, Sariego, Siero, Sobrescobio and Soto del Barco. Eastern District, comprising the municipalities of Amieva, Cabrales, Cabranes, Cangas de Onís, Caravia, Colunga, Llanes, Nava, Onís, Parres, Peñamellera Alta, Peñamellera Baja, Piloña, Ponga, Ribadedeva, Ribadesella and Villaviciosa. Western District, comprising the municipalities of Allande, Belmonte de Miranda, Boal, Candamo, Cangas del Narcea, Castropol, Coaña, Cudillero, Degaña, El Franco, Grado, Grandas de Salime, Ibias, Illano, Muros de Nalón, Navia, Pesoz, Pravia, Salas, San Martín de Oscos, Santa Eulalia de Oscos, San Tirso de Abres, Somiedo, Tapia de Casariego, Taramundi, Teverga, Tineo, Valdés, Vegadeo, Villanueva de Oscos, Villayón and Yernes y Tameza.

Each constituency was allocated an initial minimum of two seats, with the remaining 39 being distributed in proportion to their populations.

The use of the D'Hondt method might result in a higher effective threshold, depending on the district magnitude.

The electoral law allowed 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 were required to inform the relevant Electoral Commission within ten days of the election call, whereas groupings of electors needed to secure the signature of at least one percent of the electorate in the constituencies for which they sought election, disallowing electors from signing for more than one list of candidates.

Election date

The term of the General Junta of the Principality of Asturias expired four years after the date of its previous election. Elections to the General Junta were fixed for the fourth Sunday of May every four years. The previous ordinary election was held on 22 May 2011, setting the election date for the General Junta on Sunday, 24 May 2015.
