Presidents of Brazil

Last polls suggest Brazilian President Dilma Rousseff is expected to win by about 8 percent in the second round of elections for head of state held Sunday.

Rousseff is now facing Aécio Neves, the candidate of the Brazilian Social Democracy Party (PDSB) in what many experts say has been the tightest race since democracy was restored in Brazil in 1985.

Brazil's president, Dilma Rousseff won most votes in the country's presidential election on Sunday, but failed to secure the overall majority needed to avoid a run-off.

The Workers Party incumbent received about 42% of the vote and faces a run-off against Aecio Neves of the Social Democratic party,who got 34%, according to reports of the BBC News.

Around 143 million eligible voters in Brazil are going to the polls on Sunday to elect a President.

A total of 11 presidential candidates are competing for the post, with three of them estimated as the top contenders.

Experts predict a run-off stage, scheduled for October 26, with no candidate expected to receive 50% of the ballots cast on Sunday.

Brazilian President Dilma Rousseff was confirmed on Saturday as candidate for re-election to a second term of the governing Workers Party.

The elections are to take place on October 5, with a possible run-off on October 26, according to reports of the BBC News.
