A European Parliament election was held in Portugal on 19 July 1987.[1] It was the election of all 24[1] MEPs representing the Portugal constituency for the remainder of the 1984–1989 term of the European Parliament. Portugal had acceded to the European Community on 1 January 1986 and had been represented in the European Parliament by 24 appointed delegates until elections could be held. These elections took place on the same day of the legislative elections of 1987.
The Social Democrats (PSD) won the 1st European election by a landslide over the Socialists. The PSD won more than 37 percent of the votes, 15 points ahead of the PS. Note that a large chunk of the PSD vote in the 1987 legislative elections, held simultaneously with the European election, was from CDS voters that voted PSD in the general election and CDS in the EU elections. Nonetheless, the CDS won 15 percent of the votes, compared with the 4 percent in the general election ballot. Together, the center-right parties won 53 percent of the votes.
The Socialists, headed by former PM Maria de Lourdes Pintasilgo, suffered a huge defeat, polling just 22 percent, matching their general election score. The Communist/Green alliance, Democratic Unity Coalition, polled 4th place and won 11.5 percent of the votes. Finally, the Democratic Renewal Party (PRD), also suffered a very heavy defeat, winning just 4 percent of the votes and electing a sole member for the EU Parliament.
Turnout in these elections was quite high, with 72.4 percent of voters casting a ballot.
The voting method used, for the election of European members of parliament, is by proportional representation using the d'Hondt method, which is known to benefit leading parties. In the 1987 EU election, Portugal had 24 seats to be filled. Deputies are elected in a single constituency, corresponding to the entire national territory.
The major parties that partook in the election, and their EP list leaders, were:[2]
