A hoaxer pretending to be Brazilian President Luiz Inacio Lula da Silva was interviewed by some Portuguese-language radio stations before being found out.

BBC regional analyst Leonardo Rocha says the impersonator convincingly imitated President Lula's husky voice and informal style.
Radio stations that broadcast in Portuguese received an e-mail a few days ago saying President Lula was willing to be interviewed about the 2016 Olympics.
In the interview, the impersonator praises Angola for its good work ahead of the African Cup of Nations, which it will host in two month's time.
The impersonator also said: "We know we have a huge Brazilian diaspora in Australia and we're very honoured to be getting in touch with our people around the world."
