The streets of Brazil were in uproar on Sunday, with hundreds of thousands of citizens gunning for the removal of the country’s president Dilma Rousseff. Reuters reported that the agitations lost momentum late last year, but picked up again on Sunday to grow into the country’s largest one yet. The widespread anger against the leftist leader might force the country’s Congress to begin impeachment proceedings against her.

News website G1 compiled police estimates from around the country to peg the number of protesters at 3 million. While these figures might be exaggerated, the numbers are definitely upwards of 2 million. More than 500,000 people are believed to have protested in the city of Sao Paolo, while organisers at Rio De Janiero said 1 million people took to the streets in the city. The citizens chanted “Dilma out” and held banners that read “Stop the corruption”, blaming her for the country’s struggling economy, which is facing its worst recession in 25 years.

On Thursday, state prosecutors requested permission to arrest previous president and Rousseff’s mentor Luiz Inacio Lula da Silva was arrested on money laundering charges. Rousseff, who was is serving her second term after being re-elected in 2014, has said she will not step down.
