LIMA, Peru, Ramadan 05, 1437, June 10, 2016, SPA -- Peruvian electoral authorities say former World Bank economist Pedro Pablo Kuczynski has won the majority of votes in the country's closest presidential contest in five decades. His rival Keiko Fujimori has yet to concede however, according to AP. Four days after voting, the electoral board said Thursday that all ballots had been processed and Kuczynski had won 51.1 percent compared to 49.9 percent for the daughter of imprisoned ex-President Alberto Fujimori. Some ballots representing up to 50,000 votes remain in dispute but experts say it's almost impossible for Fujimori to make up the nearly vote difference to overtake Kuczynski. Fujimori was the favorite to win the runoff but lost ground in the final stretch as fellow conservative Kuczynski warned voters that the corruption and criminality associated with her father's authoritarian rule could return. --SPA 00:26 LOCAL TIME 21:26 GMT www.spa.gov.sa/w
