The "Lava Jato" operation is the largest investigation of corruption and money laundering that Brazil has ever had. It is estimated that the volume of resources diverted from the Petrobras' coffers, the state's largest company, reaches the billions of reais. On the criminal scheme were involved politicians from the Partido Trabalhista Brasilero, Partido Renovador Trabalhista/PRT, Partido Progressista Brasileiro (PPB), Partido dos Trabalhadores, Partido del Movimiento Democrático Brasileño, Partido da República, Partido da Mobilização Nacional/PMN; businessmen and executives of relevant companies in Brazil, including Construtora Norberto Odebrecht; and currency exchange operators that diverted, laundered and paid bribes to public officials, using black market channels, offshore accounts, and facade companies.
