Brazilian senator Flavio Bolsonaro led the first round of Sunday's presidential election with 47% of the vote, setting up an October 25 run-off against incumbent Luiz Inacio Lula da Silva.
Lula secured 45% of the vote in an unexpected first-round outcome that saw conservative candidates perform strongly in concurrent parliamentary elections.
The upcoming run-off represents Lula's final opportunity to secure an unprecedented fourth presidential term in a contest complicated by prior personal and political setbacks.
