Voters in Peru are selecting a new president Sunday.
The most recent public opinion polls indicate that candidates Keiko Fujimori and Pedro Kuczynski are virtually tied in the runoff election.
Fujimori, 41, is the daughter of disgraced former President Alberto Fujimori. He is serving a 25-year sentence for human rights abuses and corruption during his term.
Kuczynski, 77, is a former World Bank economist.
Both candidates are right-leaning conservatives. Kuczynski endorsed Fujimori when she ran for president in the 2011 election against outgoing President Ollanta Humala.
Fujimori had been leading in public opinion polls until recently, but the scandal around money-laundering allegations against a senior aide has taken a toll, transforming the race into a repeat performance of Fujimori's 2011 bid when she lost by a razor's edge to Humala.
In addition, many Peruvians have vowed to never vote for anyone associated with her father. She has tried to distance herself from her father's authoritarian rule of Peru from 1990 to 2000.
If Fujimori wins Sunday's runoff, she would become Peru's first female president.
