Brazil's presidential frontrunners, right-wing populist Jair Bolsonaro and his left-leaning rival Fernando Haddad, are expected to face off in a run-off later this month, according to preliminary results.
With 96 percent of votes counted, Bolsonaro garnered 46.66 percent of the votes while Haddad secured 28.43 percent, according to results from the top electoral body Superior Electoral Court (TSE).
