LONDON — Britain’s leading opposition politician has joined calls for British royal Andrew Mountbatten-Windsor to testify in the United States over his links to Jeffrey Epstein.

Nigel Farage, the right-wing populist whose party, Reform UK is leading opinion polls, said that giving evidence to a U.S. congressional investigation about Epstein could be the former prince’s only chance to clear his name.

“If Andrew believes that, yep his judgment was flawed, yep he did things he shouldn’t have done, but they weren’t coercive, they weren’t outside the law, if he believes those things, then he ought to go … for his own sake, and testify,” Farage said.

“If he doesn’t go, he’d probably never be able to show his face in public again,” the Reform leader added, warning it is “probably the only chance he’s got, to some degree … at least I think, to clear his name.”

In 2019, Mountbatten-Windsor was accused in a civil lawsuit of sexually assaulting Virginia Giuffre, one of Epstein’s accusers, but he strongly denied all allegations. He paid a financial settlement to Giuffre, but accepted no liability. The royal has faced a backlash over his friendship with Epstein, but has not been charged with a crime in either the U.K. or the U.S.

He missed a November deadline to sit for a transcribed interview that was set by the U.S. House of Representatives’ Committee on Oversight and Government Reform.

Farage’s intervention comes after Keir Starmer suggested that Mountbatten-Windsor should appear before U.S. lawmakers.

The British prime minister told reporters last week that anyone with information “should be prepared to share that information in whatever form they are asked to,” adding: “You can’t be victim-centered if you’re not prepared to do that.”

Mountbatten-Windsor is under renewed pressure to testify after the latest tranche of Epstein files released by the U.S. Department of Justice included a picture which appears to show King Charles’ brother crouching on all fours over an unknown woman.

An email exchange dated August 2010, also released Friday, showed Epstein offered the then-Duke of York the opportunity to have dinner with a woman he described as “26, russian, clevere beautiful, trustworthy.” Mountbatten-Windsor replied: “That was quick! How are you? Good to be free?”

The exchange happened a year after Epstein was released from jail following a sentence for soliciting prostitution from a person under 18.
