2003 Asturian regional election

The 2003 Asturian regional election was held on Sunday, 25 May 2003, to elect the 6th General Junta of the Principality of Asturias. All 45 seats in the General Junta were up for election. The election was held simultaneously with regional elections in twelve other autonomous communities and local elections all throughout Spain.

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.

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 election was held on 13 June 1999, setting the election date for the General Junta on Sunday, 25 May 2003.

The president had the prerogative to dissolve the General Junta and call a snap election, provided that no motion of no confidence was in process, no nationwide election was due and some time requirements were met: namely, that dissolution did not occur either during the first legislative session or within the legislature's last year ahead of its scheduled expiry, nor before one year had elapsed since a previous dissolution under this procedure. In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the General Junta was to be automatically dissolved and a fresh election called. Any snap election held as a result of these circumstances would not alter the period to the next ordinary election, with elected deputies merely serving out what remained of their four-year terms.

Opinion polls
The table below lists voting intention estimates 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. 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.
