Hundreds of thousands of people protested in Brazil last Sunday for the impeachment of left leaning president Dilma Rousseff.
She has lost support since she was re-elected less than a year ago partly due to a corruption scandal at state oil firm Petrobras.
Austerity, rising inflation and unemployment have seen her popularity plummet most strongly among the poor.
But the demonstrations were mostly middle class and linked to right wing parties who would make these problems worse.
Anti-austerity protests were set to take place on Thursday of this week. But the left wing Party for Socialism and Freedom (PSOL) warned that Rousseff’s supporters were trying to turn them into pro government rallies.
