The president of the Lower House, Eduardo Cunha, speaks to the press at the Lower House's official residence in Brasilia on May 5, 2016. Brazil's Supreme Court on Thursday suspended Eduardo Cunha, the powerful lawmaker at the centre of efforts to impeach President Dilma Rousseff, on grounds he tried to obstruct a probe into his alleged corruption. The speaker of Brazil's lower house of Congress is the architect of the impeachment drive expected to force Rousseff to step aside from office on Wednesday. SA
