LIMA — Embattled President Pedro Pablo Kuczynski offered his resignation Wednesday ahead of an impeachment vote, seeking to end a debilitating political drama playing out three weeks before the Andean nation is set to host President Trump for a regional summit.

In a nationwide televised address, Kuczynski, with his Cabinet standing behind him, said he didn’t want to become an obstacle to Peru’s development. But the former Wall Street investor lashed out at opponents, led by the daughter of former strongman Alberto Fujimori, for plotting his overthrow with damaging leaks of confidential documents that raised doubts about his integrity during his six-decade career in private business.

‘‘I don’t want my country, nor my family, to continue suffering through the uncertainty of recent times,’’ he said, adding that the campaign in favor of his removal had caused ‘‘enormous damage’’ to Peru’s democracy.

Congress must still accept his resignation before power can transfer to Vice President Martin Vizcarra, who is currently serving as Peru’s ambassador to Canada and wasn’t present for Kuczynski’s announcement. Some lawmakers were seeking to deny Kuczynski his one last act of government and demanded that he be prohibited from leaving the country.

Pressure has been building on Kuczynski to resign after the shock revelation Tuesday of secretly shot videos in which several of the president’s allies were caught allegedly trying to buy the support of an opposition lawmaker to block the conservative leader’s impeachment.
