"Mammoth demonstrations across Brazil are putting even more pressure on embattled President Dilma Rousseff as she heads into a tough week for her attempt to survive impeachment proceedings in Congress. She's fighting impeachment proceedings in Congress amid the worst recession in decades and a sprawling corruption investigation closing in on key figures in her Workers' Party.
The demonstrations were the latest in a wave of anti-government rallies that lost momentum late past year but could gain strength as a sweeping corruption investigation nears Ms Rousseff's inner circle.
The former president (Lula) himself faces charges in the corruption scandal but his presence in the government could lend order to an increasingly chaotic administration.
Sunday's demonstrations, overwhelmingly comprised of the white, older middle-class people who have railed against Rousseff for years, may have weakened the government but they don't seem to have strengthened the opposition.
Record protests against President Dilma Rousseff have all but guaranteed her impeachment by pushing hesitant lawmakers from Brazil's biggest party to favour her ouster, party sources said on Monday.
Rousseff needs Lula to maintain her links to the party base, where she is unpopular.
"If politicians don't hear our voices, they will be in trouble", Oscar Cezar Magalhães, a protester in the northeastern state of Bahia, told The Wall Street Journal. Supporters of Rousseff, Lula and the Worker's Party he founded abstained from the protests after the president and the army expressed fears of potentially violent clashes.
"She (Rousseff) has to go", said Patricio Gonzaga, an unemployed metal worker who took part in the Sao Paulo gathering. The largest scandal-deemed operation "Car Wash"- involved executives at state-run oil company Petrobras who issued inflated contracts to private businesses in exchange for bribes and kickbacks, some of which were laundered and used in political campaigns.
