Nearly 160 million Brazilians cast ballots as Lula faces Senator Flávio Bolsonaro in a deadlocked runoff, with the latest Datafolha poll showing both candidates tied at 50%.

Brazilian President Luiz Inácio Lula da Silva and challenger Flávio Bolsonaro held their final televised debate on Friday, trading barbs over the cost of living and corruption just two days before Sunday's runoff. A new Datafolha poll released the same week put both candidates at 50% of valid votes, the tightest reading of the race so far.
