Keiko Fujimori (leader of the right-wing Fuerza Popular party and daughter of former authoritarian president Alberto Fujimori) is edging closer to winning Peru's presidential election as vote counting continues. Her narrow lead over left-wing rival Pedro Castillo has prompted calls for protests from the political left, which is contesting the emerging result. The outcome is significant for Peru, South America's sixth-largest economy, as the two candidates represent sharply opposing visions for the country's economic and social future.
