1987 Madrid municipal election

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 across 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.
