Two more senior Brazilian officials have resigned in the latest blow to the government of President Dilma Rousseff.
They are Sports Minister George Hilton and Colonel Adilson Moreira, who was organising security at the Olympic Games in Rio de Janeiro set for August.
Colonel Moreira reportedly wrote that he was ashamed the country was being led by “an unscrupulous group”.
The resignations come as Ms. Rousseff battles for her government’s survival in an impeachment process.
On Monday, the Tourism Minister handed in his letter of resignation, pre-empting his PMDB party’s split from the governing coalition.
According to BBC News, congress is expected to start voting next month on whether to remove President Rousseff from office over allegations that she manipulated accounts to hide a growing deficit.
