A money-laundering investigation which began in Brazil has morphed into the biggest corruption case the region has ever seen. It has already led to the resignation of one sitting President, and the imprisonment of another.
Several major businesses in the region have been implicated, including Odebrecht, the global construction firm once associated with prosperity and ambitious public projects, now tainted by revelations of corruption. Company executives have admitted to paying bribes to politicians in several countries, in exchange for lucrative contracts.
Correspondent Stephen Gibbs was given a rare interview with Sérgio Moro. He is the prosecuting judge in Brazil overseeing several of the corruption cases resonating throughout the region, including the one involving former Brazilian President Luiz Inácio Lula da Silva.
