Dilma Rousseff

Dilma Rousseff was elected twice as the country's economy soared. But a bruising recession is now seen as the leading reason many Brazilians have turned against her.

Tens of thousands of people are suffering after losing their jobs in the wake of wide-scale corruption at Brazil's state oil company. Scores of politicians and executives have been implicated.

The second-term president faces a massive corruption scandal at the state oil company that implicates her party, rising inflation and a tanking currency. Now, her popularity is at an all-time low.
