The 1987 Asturian regional election was held on 10 June 1987 to elect the 2nd General Junta of the Principality of Asturias. All 45 seats in the General Junta were up for election. It was held concurrently with regional elections in twelve other autonomous communities and local elections all throughout Spain, as well as the 1987 European Parliament election.

The Spanish Socialist Workers' Party (PSOE) of incumbent President Pedro de Silva remained the most-voted party, but lost 13 percentage points as well as the absolute majority it had enjoyed in the previous legislature. The internal crisis within the People's Coalition after the breakup of the People's Democratic Party (PDP) from the alliance resulted in the People's Alliance (AP) standing alone in the election, losing 25,000 votes and 5 percentage points.

Disenchanted voters with the Socialist government that did not see AP as a credible opposition alternative went on to centrist Democratic and Social Centre (CDS), which saw a significant increase of its vote share and entered the General Junta with 8 seats. United Left (IU), the new incarnation of the Communist Party of Spain and its allies, lost 1 seat despite achieving more votes than in 1983.

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. 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 by law 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.

In smaller constituencies, the use of the electoral method resulted in an effective threshold based on the district magnitude and the distribution of votes among candidacies.

Election date The term of the General Junta of the Principality of Asturias expired four years after the date of its previous election. The election decree was required to be issued no later than the twenty-fifth day prior to the expiration date of parliament and published on the following day in the Official Gazette of the Principality of Asturias (BOPA), with election day taking place between the fifty-fourth and the sixtieth day from publication and set so as to make it coincide with elections to the regional assemblies of other autonomous communities. The previous election was held on 8 May 1983, which meant that the legislature's term would have expired on 8 May 1987. The election decree was required to be published in the BOPA no later than 14 April 1987, with the election taking place no later than the sixtieth day from publication, setting the latest possible election date for the General Junta on 13 June 1987.

The General Junta could not be dissolved before the expiration date of parliament except in the event of an investiture process failing to elect a regional president within a two-month period from the first ballot. In such a case, the General Junta was to be automatically dissolved and a snap election called, with elected lawmakers serving the remainder of its original four-year term.

Parliamentary composition The General Junta of the Principality of Asturias was officially dissolved on 14 April 1987, after the publication of the dissolution decree in the Official Gazette of the Principality of Asturias.

Parties and candidates 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.

Opinion polls The tables below list opinion polling results in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" column on the right shows the percentage-point difference between the parties with the highest percentages in a poll.

Voting intention estimates 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; 23 seats were required for an absolute majority in the General Junta of the Principality of Asturias.
