Upgrading Brazil’s political class

“DECENCY now!” That slogan, on a banner at a demonstration in São Paulo on March 26th, sums up what Brazilians want from their politicians. They have come to expect the opposite. Rodrigo Janot, the chief prosecutor, has asked the supreme court to open 83 investigations into politicians whom he suspects of taking part in a scheme to extract billions of dollars in bribes from construction firms, which in turn benefited from inflated public contracts. Eight ministers in the cabinet of President Michel Temer, the Speakers of both houses of congress and grandees from all the main parties are reportedly on the list. (All deny wrongdoing.) That adds to the dozens of officials already caught up in the Lava Jato (“Car Wash”) investigations into the scandal, which is centred on Petrobras, the state-controlled oil company.
