Keiko Fujimori declared winner of Peru's presidential election weeks after vote

Right-wing candidate Keiko Fujimori has been declared the winner of Peru's tight presidential election, nearly a month after the vote took place.The 51-year-old won 50.135% of voters' support in the runoff, held on 7 June, to 49.865% for left-wing candidate Roberto Sánchez - a margin of less than 50,000 votes, figures certified by Peru's electoral court show.It is the fourth time the daughter of disgraced former President Alberto Fujimori has sought the South American nation's presidency, promising this time to oversee a crackdown on organised crime.Her election, coinciding with the election of Abelardo de la Espriella in Colombia, marks a shift towards the right in Latin American politics.Fujimori said she would assume the role of president "with responsibility, humility and a deep sense of duty"."Each day of this transition process is an opportunity to listen, engage in dialogue and arrive prepared at the start of the new government," she added, with what appeared to be a nod to her thin mandate.Sánchez, 57, has alleged the runoff election had been "seriously compromised" and threatened legal action, arguing that strong support for Fujimori among Peruvian voters abroad was a sign of irregularities.After the result was declared on Friday, his party appealed against the electoral court's proclamation, calling for the vote to be nullified.
