The latest polls put Senator Flávio Bolsonaro slightly ahead of President Luiz Inácio Lula da Silva. All fall within a 2 per cent margin of error, so many experts call the race a toss-up.

Bolsonaro took the most votes in the first round on Oct 4, with 56,104,503 votes to Lula's 53,879,538, though most polls had expected a narrow Lula win.

Bolsonaro, 42, is the son of former president Jair Bolsonaro, who is under house arrest serving a 27-year sentence over efforts to overturn the 2022 vote. Lula, 80, seeks a fourth, non-consecutive term.
