1999 Portuguese legislative election


The Portuguese legislative election of 1999 took place on 10 October. The Socialist Party was aiming a second term under the lead of António Guterres, in the end the Socialists won the election, but missed what would be an historical absolute majority for the party by just one MP.
The Social Democratic Party under the lead of José Manuel Durão Barroso was still away from the preferences of the majority of the Portuguese people, after the ten years cycle under the lead of Cavaco Silva that had terminated four years before. The Democratic Unity Coalition achieved an important climb in the scorecard, against those who predicted its irreversible decline after the end of the Socialist Bloc in the early 1990s. For the first time, the Left Bloc, formed after the merger of several minor left-wing parties became represented in the parliament after electing two MPs. Turnout in this election was very low, only being surpassed in 2009 and 2011 when turnout was just less than 60%.
Voter turnout reached only 61% of voters, one of the lowest ever recorded.

Electoral system

The Assembly of the Republic has 230 members elected to four-year terms. Governments do not require absolute majority support of the Assembly to hold office, as even if the number of opposers of government is larger than that of the supporters, the number of opposers still needs to be equal or greater than 116 for both the Government's Programme to be rejected or for a motion of no confidence to be approved.
The number of seats assigned to each district depends on the district magnitude. The use of the d'Hondt method makes for a higher effective threshold than certain other allocation methods such as the Hare quota or Sainte-Laguë method, which are more generous to small parties.

Parties

The major parties involved were listed with their leaders:
António Guterres, leader of the Socialist Party, was nominated Prime Minister for the second time, and missed the absolute majority by one MP, achieving exactly half of the 230 MPs.
