A municipal election was held in Madrid on Wednesday, 10 June 1987, to elect the 3rd City Council of the municipality. All 55 seats in the City Council were up for election. It was held concurrently with regional elections in thirteen autonomous communities and local elections all throughout Spain, as well as the 1987 European Parliament election.
The Spanish Socialist Workers’ Party (PSOE) won the election, but lost its absolute majority and lost 137,000 votes compared to 1983. The People’s Alliance (AP), which stood separately after the breakup of the People’s Coalition in 1986, failed to meet the level of support reached by the coalition in 1983 and also lost votes and seats. Benefitting from both parties’ losses was the Democratic and Social Centre (CDS), which, with its 8 seats and 15% of the votes, entered the City Council for its first and only time and went on to hold the balance of power. United Left (IU), an electoral coalition comprising the Communist Party of Spain and other left-wing parties, continued on its long-term decline and lost 1 more seat, barely obtaining 100,000 votes and 6% of the share.
AP and CDS together reached an absolute majority, but failure on reaching an agreement resulted in Socialist Juan Barranco being re-elected as mayor. However, in June 1989, both parties agreed to present a motion of censure on Barranco and elect Agustín Rodríguez Sahagún from the CDS as new mayor, ousting the PSOE from power in the city after a 10-year rule.
Under the 1978 Constitution, the governance of municipalities in Spain—part of the country’s local government system—was centered on the figure of city councils (Spanish: ayuntamientos), local corporations with independent legal personality composed of a mayor, a government council and an elected legislative assembly.[1][2] In the case of Madrid, the top-tier administrative and governing body was the City Council of Madrid.[3]
Voting for local assemblies was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered and residing in the municipality of Madrid and in full enjoyment of their political rights (provided that they were not sentenced—by a final court ruling—to deprivation of the right to vote, nor being legally incapacitated), as well as resident non-nationals whose country of origin allowed Spanish nationals to vote in their own elections by virtue of a treaty.[2][4][5]
Local councillors were elected using the D’Hondt method and a closed list proportional voting system, with an electoral threshold of five percent of valid votes (which included blank ballots) being applied in each municipality.[6] Each municipality constituted a multi-member constituency, entitled a number of seats based on the following scale:[7]
| Population | Councillors |
|---|---|
| <250 | 5 |
| 251–1,000 | 7 |
| 1,001–2,000 | 9 |
| 2,001–5,000 | 11 |
| 5,001–10,000 | 13 |
| 10,001–20,000 | 17 |
| 20,001–50,000 | 21 |
| 50,001–100,000 | 25 |
| >100,001 | +1 per each 100,000 inhabitants or fraction +1 if total is an even number |
The law did not provide for by-elections to fill vacated seats; instead, any vacancies that occurred after the proclamation of candidates and into the legislative term were to be covered by the successive candidates in the list and, when required, by the designated substitutes.[8]
The mayor was indirectly elected by the local assembly.[2] A legal clause required candidates to earn the vote of an absolute majority of councillors, or else the candidate of the most-voted party was to be automatically appointed to the post. In the event of a tie, the appointee was to be determined by lot.[9]
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; 28 seats were required for an absolute majority in the City Council of Madrid.
