Peru's presidential candidate Keiko Fujimori smiles during a news conference in Lima, in this file picture taken May 12, 2011. Peru's presidential front-runner Keiko Fujimori has hired former New York City Mayor Rudy Giuliani as an adviser, trying to bolster her law-and-order credentials without relying on the image of her divisive father, jailed former President Alberto Fujimori, Reuters reported on May 16, 2011.
