Banco Master scandal shakes Brazil's neck-and-neck presidential race

Brazil's Banco Master fraud scandal has engulfed both leading presidential candidates ahead of Sunday's first-round vote. Incumbent Lula da Silva and far-right Senator Flavio Bolsonaro are locked in a tight race, with rejection rates above 50 percent for both. The collapsed lender's owner faces money-laundering charges, and Bolsonaro is under investigation over alleged ties to him.
