Brazilians go to the polls in presidential elections
Polls have opened in Brazil in what correspondents say is the tightest presidential election for decades.
Incumbent left-leaning President Dilma Rousseff of the Workers Party (PT) faces centrist Aecio Neves of the Brazilian Social Democracy Party (PSDB) in the second run-off round.
Both candidates have pledged to kick-start Latin America's largest economy and make it more competitive.
Voting began at 08:00 (10:00 GMT) and will end at 20:00.
The latest opinion polls showed President Rousseff with a slight lead over the opposition candidate.
