Peru’s leftist ⁠presidential candidate Roberto Sanchez will face ⁠Keiko Fujimori in the June run-off after narrowly securing second place in April’s first-round vote, official results showed Friday, with 100 per cent of votes tallied.

The month-long count led to allegations of fraud in ‌the politically turbulent South American nation, notably from right-wing candidate Rafael Lopez Aliaga, who narrowly trailed Sanchez for much of the counting process.

Fujimori, the daughter of late former president Alberto Fujimori, is seeking the presidency for a fourth time after topping the fragmented field.

Sanchez, a congressman who ⁠is running with the backing of jailed former leftist President Pedro Castillo, stood ‌at 12.03 per cent, narrowly ahead of Lopez Aliaga, the ultraconservative former mayor of Lima, with 11.90 per cent.

Sanchez had a near 21,210-vote lead ‌over Lopez Aliaga.

The prolonged count since the April 12 first-round prompted the ⁠resignation of ⁠the country’s top electoral official, who is now under investigation by the public prosecutor. European ‌Union observers have said they found no concrete evidence of fraud.
