The speaker of Brazil's lowest house of Parliament, Eduardo Cunha, has initiated impeachment proceedings against President Dilma Rousseff. The political showdown between two leaders described as "arch enemies" was put in stark terms on the Thursday edition of Portuguese-language Brazilian daily Correio, which used the English word "Impeachment" on the front page.

Rousseff is facing allegations that she violated fiscal laws to help her win a second term, in yet another episode of Brazil's ongoing economic and political crises. But Cunha, who himself is accused of corruption and of laundering money via bank accounts in Switzerland, launched the proceedings one day after parliamentary allies of Rousseff said they would push ahead with a procedure to oust Cunha for corruption.

Reacting after the announcement, Rousseff said she was "outraged" at the impeachment procedure, and insisted she had committed "no wrongful act."

In a direct reference to the accusations against Cunha, the Brazilian president said, "I don't have any offshore bank accounts, I have no hidden assets."
