The Executive Committee of Brazil’s Workers Party (PT) is meeting to discuss the arrest of José Diceu, a former top party leader and chief aide to President Lula da Silva. Diceu was arrested on Monday in connection with the Petrobras corruption scandal. His lawyer charges that Diceu is a scapegoat, while others see his arrest as an attempt to associate him with an earlier scandal and prevent Lula from emerging as an alternative to President Dilma Rousseff. teleSUR
