LIMA — Peru鈥檚 center-right President Pedro Pablo Kuczynski announced his resignation on Wednesday after vote-buying allegations ensnared him in a fresh scandal on the eve of an impeachment vote, capping months of political turmoil in one of Latin America鈥檚 most stable economies.

Mr. Kuczynski, a 79-year-old former Wall Street banker who once held US citizenship, promised a 鈥渃onstitutional and orderly鈥 transition of power to end what he described as a hostile political climate that had made governing nearly impossible.

But Mr. Kuczynski, who is expected to be replaced by Vice-President Martin Vizcarra on Friday, denied allegations of wrongdoing and blamed the premature end of his five-year term on the right-wing opposition party that controls Congress.

鈥淚鈥檝e worked for nearly 60 years of my life with complete honesty. The opposition has tried to depict me as a corrupt person,鈥 Mr. Kuczynski said in a pre-recorded video message to the nation that broadcast as he left the presidential palace.

But Mr. Kuczynski added, 鈥淚 think what鈥檚 best for the country is for me to resign鈥 I don鈥檛 want to be an obstacle for the nation鈥檚 search for a path to unity and harmony.鈥

鈥楳ORALLY UNFIT鈥
Lawmakers agreed to accept Mr. Kuczynski鈥檚 resignation instead of moving forward with a vote scheduled for Thursday on whether to oust him on grounds he was 鈥渕orally unfit鈥 to govern, said the president of Congress, Luis Galarreta. Mr. Galarreta said he would swear Mr. Vizcarra in as president at around midday Friday.

A former governor of a mining region who once helped secure community support for Anglo American Plc鈥檚 Quellaveco copper project, Mr. Vizcarra has served as Peru鈥檚 ambassador to Canada since September and is currently in Ottawa.

In recent days, Mr. Vizcarra has received public assurances from opposition lawmakers that they will support his government.

But he will take office amid a fractured party, widespread disgust for elected officials in Peru and inherit economic growth that slowed to 2.5% last year.

Mr. Vizcarra, who turns 55 years old on Thursday, appealed to the public to pull through the crisis on Twitter.

鈥淚鈥檓 outraged by the current situation like the majority of Peruvians,鈥 the vice-president said.

鈥淏ut I鈥檓 convinced that together we can show that we can once more push forward.鈥

Mr. Kuczynski had been scheduled to welcome Donald Trump on the US president鈥檚 first visit to Latin America next month, where many of the region鈥檚 leaders plan to pressure Venezuelan President Nicolas Maduro to enact democratic reforms.

A White House official, speaking on background, said that Mr. Trump still plans to attend the summit. — Reuters
