LIMA, Peru — Peruvian voters will have to wait until at least Monday to learn the outcome of Sunday’s presidential election after the process was mired with logistical issues that even left thousands of people in the country and abroad unable to cast ballots.

The problems prompted electoral authorities to allow more than 52,000 residents of Peru’s capital, Lima, to vote on Monday. The extension, announced after vote counting began Sunday evening, also covers Peruvians registered to vote in Orlando, Florida, and Paterson, New Jersey.

Authorities initially reported 63,300 people could vote Monday but later revised down the figure.

Voting is mandatory for Peruvians from the ages of 18 to 70. Failure to do so comes with a fine of up to $32.

A former minister, a comedian and a political heiress are among 35 candidates vying to become Peru’s ninth president in just 10 years.

The election comes amid a surge in violent crime and corruption that has fueled widespread discontent among voters, who largely view candidates as dishonest and unprepared for the presidency. Many of the contenders have responded to the crime concerns with wide-ranging proposals, including building megaprisons, restricting food for prisoners and reinstating the death penalty for serious crimes.

Nurse Heidy Justiniano had not decided who to vote for while already in line outside a public school in Lima.

“There’s so much crime, so many robberies on every corner; a bus driver was killed. What matters most to us right now is safety, the lives of every person,” Justiniano, 33, said. “Politicians don’t always keep their promises. This time, we have to choose our president wisely so that he can improve Peru.”

More than 27 million people are registered to vote. Of those, about 1.2 million cast ballots abroad, mainly in the United States and Argentina.

A presidential candidate needs more than 50% of votes to win outright. However, a runoff in June is virtually assured given the deeply divided electorate and the pool of candidates, the largest in the Andean country’s history.

Voters are also being asked to choose the members of a bicameral Congress for the first time in more than 30 years, following recent legislative reforms that concentrate significant power in the new upper chamber.
