The 1987 Cantabrian parliamentary election was held on Wednesday, 10 June 1987, to elect the 2nd Regional Assembly of Cantabria, the regional legislature of the Spanish autonomous community of Cantabria. All 39 seats in the Regional Assembly were up for election, an increase of four compared to the previous election. The election was held simultaneously with regional elections in 12 other autonomous communities and local elections all throughout Spain, as well as the 1987 European Parliament election.
The election was a victory for the People's Alliance (AP), which despite the breakup of the People's Coalition with the People's Democratic Party (PDP) and the Liberal Party (PL), remained the Assembly's largest force, albeit losing the absolute majority of seats it had held in the previous parliament. As in other communities, the Spanish Socialist Workers' Party (PSOE) lost votes and seats, while the Democratic and Social Centre (CDS) and Regionalist Party of Cantabria (PRC) made gains.
The legislature would be marked by dissensions between the elected President of Cantabria, Juan Hormaechea, and his own party AP (from 1989 the People's Party). In 1989 the PP would demand Hormaechea's resignation, but he would continue in a government formed by independents. In December 1990, he will be forced out by a no-confidence motion supported by PP, PSOE, PRC and CDS, which would result in a coalition government headed by Socialist Jaime Blanco being formed until the 1991 election.
Electoral system
The number of seats in the Regional Assembly of Cantabria was set to a fixed-number of 39. All Assembly members were elected in a single multi-member district, consisting of the Community's territory (the province of Cantabria), using the D'Hondt method and a closed-list proportional representation system.
Voting was on the basis of universal suffrage in a secret ballot. Only lists polling above 5% of valid votes in all of the community (which include blank ballots—for none of the above) were entitled to enter the seat distribution.
