Brazilian President Dilma Rousseff (R) and Vice-President Michel Temer attend the launching ceremony of the Investment Program in Energy at Planalto Palace in Brasilia, on August 11, 2015. Analysts say Brazil's once booming economy suffers deep underlying illnesses, notably the massive corruption scandal unfolding at national oil company Petrobras and rippling across other top companies and into political circles. It is also on the brink of recession. According to a recent poll that put Rousseff's approval rating at eight percent, she is now Brazil's most unpopular democratically elected president since a military dictatorship ended in 1985.
