June 8 (UPI) -- Preliminary results from Sunday's presidential runoff election in Peru showed an exceptionally tight race between right-wing candidate Keiko Fujimori of the Popular Force party and Roberto Sánchez of leftist coalition Together for Peru.

Wwith 93% of ballots counted, Fujimori held a narrow lead with 50.08% of the vote compared with 49.92% for Sánchez, according to figures released Monday by the National Office of Electoral Processes.

Official results showed Fujimori won the majority of votes in Lima and major urban centers along Peru's northern coast, while Sánchez secured strong support in the Andean south, the Amazon region and rural areas across the country.

Amid the razor-thin margin, officials from Peru's National Jury of Elections and both candidates urged calm as the count continues.
