What to know as Brazil prepares for tense presidential run-off
Polls show leftist incumbent Lula closing gap on right-wing rival Flavio Bolsonaro ahead of second round of voting.
Voters in Brazil are headed to the polls for the second time in one month, as Senator Flavio Bolsonaro and President Luiz Inacio Lula da Silva square off in a run-off election to decide who will hold the presidency for the next four years.
While Bolsonaro outperformed expectations during the first round of voting on October 4, when he beat Lula by less than two percentage points but failed to secure the majority needed to avoid a run-off, the leftist president has sought to rally supporters ahead of the second round.
The vote on Sunday will decide whether Brazil joins a growing list of countries across Latin America that have handed victories to far-right candidates promising closer ties with the United States, a hard hand on crime and insecurity, and market-friendly economic policies.
He has pledged a militarised approach towards crime and insecurity posed by organised gangs in close partnership with the administration of United States President Donald Trump, who has sought to expand US military involvement across Latin America through ties with right-wing allies in the name of combatting crime.
