Brasilia, December 16 (teleSUR-RHC)-- Brazilian social movements are taking to the streets on Wednesday to reject an impeachment process launched by embattled opposition leader Eduardo Cunha against President Dilma Rousseff.

“There will be thousands of us in the streets on December 16th.  It will be the National Day of Action against Impeachment, fiscal austerity and calling for the resignation of Cunha.  We invite all Brazilians to participate,” Brazil’s largest labor union, the CUT, said in a press release.

The rally will include the participation of more than 70 grassroots organizations, including the Landless Workers Movement, which has vowed to defend the Rousseff government and the country's democracy through street mobilizations.

“The objective for Brazilian people is to see the expansion of rights, the deepening and strengthening of democracy and popular reforms. The impeachment is a clear setback towards these goals,” the statement added. 

Meanwhile, the Supreme Court will rule Wednesday on whether to allow the impeachment proceedings against President Rousseff to continue.

Brazilian opposition launched the impeachment process against Rousseff earlier this month on the grounds of illegal accounting practices.

The impeachment campaign lead by Cunha, a fierce critic of Rousseff, is currently facing pressure to resign due to corruption allegations.

On Tuesday, 50 federal deputies signed a letter to the supreme court calling for Cunha to stand down from his position as speaker while under investigation.
