A new Vox Brasil poll gives President Lula 51% of valid votes against 49% for Flávio Bolsonaro, a technical tie a week before Brazil's October 25 presidential runoff.

A fresh survey from pollster Vox Brasil shows President Luiz Inacio Lula da Silva narrowly ahead of challenger Flavio Bolsonaro in Brazil's presidential runoff, with 51% of valid votes against 49%. Pollsters describe the gap, within the margin of error, as a technical tie, published exactly seven days before voters return to the polls on October 25.

The result caps a campaign that has stayed essentially deadlocked for weeks, with earlier surveys from rival pollsters also pointing to a race too close to call. Flavio Bolsonaro has emerged as the standard-bearer for the conservative bloc in the second round, while Lula is seeking to extend his hold on Brazil's presidency. Latin America's largest economy, and its currency and stock markets, have shown sensitivity to shifts in the polling as investors weigh what either outcome could mean for fiscal policy and spending.

With just a week of campaigning left, both camps are expected to intensify efforts to mobilize undecided voters in the final stretch. Vox Brasil said it would continue tracking voter sentiment through the final days before the runoff, when more than 150 million Brazilians are eligible to cast ballots.
