Leftist congressman Roberto Sanchez has taken a slim lead against conservative Keiko Fujimori in Peru's presidential race as vote-counting continued with a final result potentially weeks away.
With about 94.9 per cent of votes tallied, Sanchez rose to 50.10 per cent, while Fujimori dropped to 49.90 per cent.
Most voters who cast ballots in the election on Sunday said they were concerned about crime and the economy, and a rightward shift similar that to seen in other recent Latin American contests had been widely predicted.
