The nail-biter race to become Peru's next president tightened as the daughter of imprisoned ex-president Alberto Fujimori gained ground on her rival thanks to a larger haul of votes trickling in from remote rural areas and embassies abroad.

Former World Bank economist Pedro Pablo Kuczysnki's razor-thin lead over Keiko Fujimori shrank to fewer than 75,000 votes late Monday night. With almost 95 percent of polling stations counted, Kuczynski had 50.2 percent of the votes compared with Fujimori's 49.8 percent.

While two quick counts showed Kuczynski prevailing in a tight contest, still to be counted are the ballots of 885,000 Peruvians eligible to vote abroad and who turned out massively for Fujimori in the 2011 election.

Both candidates remained silent Monday urging supporters to await the final tally.
