Mensalão scandal
The Mensalão scandal (Portuguese: Escândalo do Mensalão, IPA: [isˈkɐ̃dɐlu du mẽsɐˈlɐ̃w]) was a major parliamentary scandal in 2005 that threatened to bring down the government of Brazil, in which Luiz Inácio Lula da Silva's administration was accused of vote-buying. Mensalão is a neologism, an augmentative variant of the word for "monthly payment" (salário mensal or mensalidade).
