The election renewed all 230 members of the Assembly of the Republic. There was a reduction of 20 seats compared with previous elections, due to the 1989 Constitutional revision.Sistema Eleitoral Português: Problemas e Soluções, "Leya", Marina Costa Lobo, 7 November 2018 For the first time in Portuguese democracy, an election was held after the four years of the legislature had been fully completed."A "década de betão" do cavaquismo", RTP, 7 March 2016. Retrieved 15 January 2025. The Social Democratic Party, under the leadership of Cavaco Silva, won a historic third term and obtained an absolute majority for a second consecutive time. Although losing 13 seats due to the reduction in the total number from 250 to 230, the loss was only 3 seats if the results of the 1987 election are counted with the new seat distribution, while at the same time obtaining a higher percentage of votes than four years prior. Cavaco Silva became the first Prime Minister since Hintze Ribeiro, in 1904, to lead a party into three successive democratic election victories. The Socialist Party, at the time led by Jorge Sampaio, the future President of Portugal, increased its share by 7 percentage points and gained 12 MPs, a gain of 16 if compared with the new seat distribution, but did not manage to avoid the renewal of the Social Democrats' absolute majority. Like four and six years earlier, and like 1979 and 1980, the PS failed to win a single district. In the first legislative election after the fall of the Eastern Bloc, the communist dominated Democratic Unity Coalition lost much of its electoral influence, losing almost 10 MPs and 3 percentage points, but were able to hold on to the district of Beja by a slight margin over the PSD. On the right, the CDS could not recover its past influence, mainly to the effect of tactical voting for the Social Democratic Party by right-wing voters, increasing its parliamentary group by only 1 MP. The National Solidarity Party, using a populist campaign, achieved for the first time an MP, in what would be the only presence of such party in the Parliament. Voter turnout fell to 67.8 percent, and for the first time below 70 percent of the electorate.
