The United States said Wednesday that relations with Pakistan will suffer if it does not probe irregularities in last month`s election and rerun votes if needed.
Donald Lu, the top US diplomat for South Asia, told lawmakers that the United States had "serious concerns" about the conduct of the February 8 election and ongoing disruptions of media and social media, including a prolonged shutdown of X, formerly known as Twitter.
"The Election Commission of Pakistan, should it find that these irregularities are substantiated, should rerun elections where there`s been interference," Lu told a sometimes raucous hearing of a House Foreign Affairs subcommittee.
"We have enjoyed 76 years of partnership with this country. It will be an impediment to our relationship if Pakistan does not have a democratic process that upholds its own constitution," Lu said.
Lu said the United States was not considering any major new military sales to Pakistan, a Cold War ally whose army and intelligence apparatus has long played a dominant role in politics and whose past links with Afghanistan`s Taliban soured ties with Washington.
Ahead of the election, former prime minister and cricket star Imran Khan was jailed and barred from running, with his Pakistan Tehreek-e-Insaf (PTI) party subject to a crackdown.
Khan`s candidates nonetheless won more seats than any party, but rival Shehbaz Sharif became prime minister in a shaky coalition between two dynastic parties.
Khan, who was removed as prime minister by a parliamentary vote two years ago, has frequently criticized the US military and has alleged that the United States engineered his removal.
Khan`s supporters have cited a leaked Pakistani diplomatic document that said that Lu had voiced alarm over the then prime minister`s relationship with Russia during the invasion of Ukraine.
Lu, who was repeatedly disrupted at the hearing by pro-Khan demonstrators, strongly denied that he ever tried to remove Khan.
"This conspiracy theory is a lie. It is a complete falsehood," he said.
"We respect the sovereignty of Pakistan. We respect the principle that Pakistan -- Pakistani people -- should be the only ones choosing their own leaders through a democratic process."
Lu, a career diplomat, said that he has received death threats and his family has been threatened over the allegations.
