Peru's congress has voted by a wide margin to allow impeachment proceedings to begin against President Pedro Pablo Kuczynski over his ties to the Brazilian construction giant implicated in Latin America's biggest corruption scandal.

It's the second time lawmakers are threatening the former Wall Street investor with removal.

Opposition leaders attempted to impeach Kuczynski last year after an investigation revealed Odebrecht had made $782,000 in payments to his private consulting firm more than a decade earlier.

Kuczynski narrowly avoided being voted out after a small opposition faction including the son of then-jailed former President Alberto Fujimori abstained.

Days later, Kuczynski pardoned Fujimori from a 25-year jail sentence for human rights abuses committed during his decade-long rule.

Kuczynski has denied any wrongdoing and says he will not step down.
