The approval rating of Brazilian President Dilma Rousseff has fallen to a level not seen in the more than two decades since a president was impeached for corruption, her hit coming amid an economic crunch and a huge corruption scandal at the state energy company.

The Datafolha poll published Sunday by the newspaper Folha de S.Paulo says only 10 percent of those surveyed consider Brazil's government to be "great" or "good." By contrast, 65 percent said the government is a "failure."

The approval rating was the lowest for a Brazilian leader since 1992, when President Fernando Collor de Mello was forced from office after being impeached for corruption.

The Datafolha poll was based on interviews with 2,840 people Wednesday and Thursday and had an error margin of 2 percentage points.
