Brazilian President Dilma Rousseff and opposition leader Aecio Neves are tied in the presidential race, opinion polls said.
According to the opinion polls released Thursday night, Neves will gain 46 percent of the vote in a run-off scheduled for Oct 26, while Rousseff will get 44 percent, Xinhua reported.
The candidates are technically tied as the polls had margins of error of two points.
In the first round of election held Oct 5, Rousseff won 41.6 percent of the votes, compared with 33.6 percent for Neves.
However, Neves consolidated his position after winning the support of several political parties, including the the Socialists, whose candidate, Marina Silva, won 21 percent of the votes in the first round.
Silva herself has not declared support to any of the candidates, though she is believed to either support Neves or remain neutral.
The Socialism and Freedom Party, which ranked fourth in the first round, has recommended support for Rousseff or blank votes.
Prominent leaders of the party have declared open support for Rousseff.
