The results of the general election in Peru have been delayed after tens of thousands of people were unable to vote due to technical and logistical problems at a number of polling stations.
The electoral authorities have granted a one-day extension to more than 50,000 voters who could not cast their ballots on Sunday.
A preliminary count of half the votes that were cast put conservative candidate Keiko Fujimori slightly ahead of the right-wing former mayor of the capital, Lima, Rafael López Aliaga - but the battle for second place is still very close-run.
All candidates are far short of the 50% of votes needed to win outright, making a run-off between the top two candidates on 7 June almost certain.
Voters who experienced problems in Lima and at polling stations abroad - such as in Orlando, Florida and Paterson, New Jersey - will be able to cast their ballots on Monday, the electoral authorities ruled.
