Brazil has been rocked by a series of corruption scandals in recent years - Operation 'Car Wash' is just one of the many ongoing investigations that stretch into the highest levels of business and politics. President Michel Temer is himself implicated in a scandal that could well bring his term of office to an early end - making him the country's second president ousted within a year. His approval ratings are rock bottom, street protests against him are growing, and the Supreme Court has now ordered him to answer police questions about the allegations against him. On this week's Newshour Extra, Owen Bennett Jones and his guests ask how Brazil, once hailed as a bright hope of emerging BRICS nations, has reached this point of crisis and whether the corruption investigations can clean up the mess.
