The center-left Socialist Party has retained power in Portugal's parliamentary elections, AP reported.
Results from more than 98 percent of votes counted give the Socialists 36.5 percent of Sunday's ballot, compared with 29 percent for the center-right opposition Social Democratic Party.
The Social Democrats have conceded defeat.
Three smaller parties shared the remaining votes cast in the elections.
The Socialists had campaigned on a promise of a big-spending stimulus package to drive the country out of an economic crisis, which has brought the highest jobless rate in over 20 years.
Prime Minister Jose Socrates also has vowed to stick with a social and economic reform program that has antagonized many, especially trade unions.
