Former Brazilian President Luiz Inacio Lula da Silva addresses supporters during his visit to Station Square, in Belo Horizonte, as part of his "Lula for Brazil" bus tour campaign, in Minas Gerais, Brazil on October 30, 2017. Lula da Silva embarked on his most audacious challenge yet: to recapture the presidency -- and avoid prison. The presidential election won't take place until October 2018 and the many potential candidates are still keeping below the radar. Campaigning is not even officially allowed. / AFP PHOTO / DOUGLAS MAGNO
