Brazilians voted on Sunday in a high-stakes presidential election pitting incumbent Luiz Inacio Lula da Silva against Senator Flavio Bolsonaro, ideological opposites who are each seen as having a shot at an outright victory.

If no candidate gets more than 50 per cent of the vote, the top two vote-getters will head to a runoff on October 25 in Latin America’s economic powerhouse. Ten other candidates are expected to garner much smaller numbers of votes on Sunday.
