LIMA (Reuters) - Far left candidate Pedro Castillo is leading the Peruvian presidential race, according to a fast count conducted by pollster Ipsos, with conservative Keiko Fujimori in second place. Ipsos said a fast count of 69.1% ballots from around the country showed Castillo had won 18.6% of the vote and Fujimori had won 14.5%, meaning both would go to a second round of the vote in June. Ipsos said its findings had a one-point margin of error.
