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.
