DHAKA: Millions of Brazilians are set to vote for a new president in what correspondents say is the tightest vote the country has seen in 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 opens at 08:00 (10:00 GMT), reports the BBC.

The latest opinion polls showed president Rousseff with a slight lead over the opposition candidate.

A survey by pollster Datafolha gave her 52% voter support against 48% for Neves.

A separate survey by polling firm Ibope gave the incumbent 53% against 47% for her challenger.

Both polls had a margin of error of plus or minus 2%.
