Brazil’s Transparency Minister Fabiano Silveira resigned on Monday after leaked recordings suggested he tried to derail a sprawling corruption probe, the latest cabinet casualty impacting interim President Michel Temer’s administration.

Fabiano Silveira was in charge of the ministry tasked with fighting corruption but left after a recording was made public, which seems to show him trying to derail a corruption investigation at the state oil company.

Dozens of protesting civil servants occupied the office of Minister Fabiano Silveira earlier on Monday after the audio was made public. Hundreds later marched to the presidential palace, setting off fireworks and protesting against changes Acting President Temer made to the ministry, formerly known as the Comptroller-General’s Office.

Last week the planning minister stepped aside after a similar recording was released.

Mr. Jucá also confirmed it was his voice but has denied any wrongdoing and said he never planned to hamper the investigation, known as Operation Car Wash,

The anonymous leaks have put much of the capital on edge, creating a kind of nervousness among politicians and their advisers over what might emerge next.
