Peru's presidential candidate Keiko Fujimori announces her defeat in the Peruvian elections to the media in Lima, June 6, 2011. Former army commander Ollanta Humala claimed victory in Peru's presidential election on Sunday as investors worried that his left-wing policies could ruin a long economic boom. With 80 percent of ballot boxes counted, Humala had a narrow but growing lead of 1.4 percentage points over right-wing lawmaker Keiko Fujimori, the daughter of jailed former President Alberto Fujimori.
