Thousands marched in Peru's capital, Lima, to oppose presidential frontrunner Keiko Fujimori, just four days before the election.
Protesters chanting slogans such as "Keiko No!" Keiko Fujimori’s father, controversial former president Alberto Fujimori, ruled from 1990 to 2000 and is currently serving a 25-year sentence for human rights abuses and corruption during his term.
Keiko Fujimori, 41, has tried to distance herself from her father by promising not to revive his hardline methods or authoritarian rule, and proposing generous spending on infrastructure, including building more prisons in an effort to combat crime.
Fujimori faces 77-year-old Kuczynski in a runoff election Sunday. She beat him by a large margin in the first round of voting.
The center-right politician would be Peru's first female president.
