Rousseff vows not to quit as scandal grows

Brazilian President Dilma Rousseff said on Tuesday she had committed no crime and would never resign despite corruption allegations, as the scandal threatening her government escalated with dozens of new arrests.

In a defiant speech from the presidential palace, the leftist leader accused her opponents of seeking to stage a "coup against democracy", with impeachment proceedings and mass protests calling for her ouster.

"I will never resign," she told a cheering crowd of supporters. "Not under any circumstances."
