Hundreds of thousands of Brazilians flooded the streets on Sunday in the biggest ever protests calling for President Dilma Rousseff¡¯s removal, reflecting rising popular anger that could encourage Congress to impeach the leftist leader.

The demonstrations were the latest in a wave of anti-government rallies that lost momentum late last year but have regained strength as a sweeping corruption investigation nears Rousseff¡¯s inner circle.

From the Amazon jungle city of Manaus to the business hub of Sao Paulo and the capital Brasilia, protesters marched in a nationwide call for Rousseff to step down, raising pressure on lawmakers to back ongoing impeachment proceedings against her that just a few weeks ago appeared to be doomed.
