Electoral system

The 60 members of the European Parliament allocated to Spain as per the 1985 Treaty of Accession were elected using the D'Hondt method and a closed list proportional representation, with no electoral threshold being applied in order to be entitled to enter seat distribution. Seats were allocated to a single multi-member constituency comprising the entire national territory. Voting was on the basis of universal suffrage, which comprised all nationals over eighteen and in full enjoyment of their political rights.^[2][3] The use of the electoral method resulted in an effective threshold based on the district magnitude and the distribution of votes among candidacies.^[4]

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. In order to be entitled to run, parties, federations, coalitions and groupings of electors needed to secure the signature of at least 15,000 registered electors; this requirement could be lifted and replaced through the signature of at least 50 elected officials—deputies, senators, MEPs or members from the legislative assemblies of autonomous communities or from local city councils. Electors and elected officials were disallowed from signing for more than one list of candidates.^[2]
