The disruption has sparked protests across the country, as many voters point to irregularities and question the credibility of the process, despite repeated assurances from electoral authorities that the outcome will reflect the popular will.
Officials said more than 63,000 voters in Lima and other areas, including some abroad, would be given a second chance to vote on Monday, 13 April, after ballot papers failed to reach dozens of polling stations. The delay means results are unlikely before at least 14 April, fuelling concerns over transparency and turnout in what is already a tightly contested race with 35 candidates.
