LIMA, June 9 — Peruvian socialist candidate Pedro Castillo held on to a narrow lead late on Tuesday in the country’s runoff presidential election, as tensions rose over contested ballots and accusations of fraud, which sparked protests outside the elections office. Castillo, who has worried markets and mining firms with his plans to shake up the copper-rich country’s politics, held a slim lead of some 50.3 per cent, ahead of right-wing rival Keiko Fujimori on 49.7 per cent, with almost 98 per cent of the votes tallied.
