UK Prime Minister Keir Starmer had warned Andrew Mountbatten-Windsor that “nobody is above the law” just hours before the disgraced ex-royal was arrested Thursday.

Starmer gave the seemingly prescient warning in an interview with the BBC early Thursday when asked if the king’s brother should dish on what he knows about his late friend, notorious pedophile Jeffrey Epstein.

“Anybody who has any information should testify,” said Starmer, whose own position as leader has been tested by the latest Epstein files.

“So whether it’s Andrew or anybody else, anybody who has got relevant information should come forward to whatever the relevant body is, in this particular case we’re talking about Epstein, but there are plenty of other cases.”

Starmer said “everyone is equal under the law” and “nobody is above the law.”

“That is the principle. It’s a long-standing principle, it’s a very important principle of our country, our society, and it applies, and it has to apply in this case, in the same way as it would apply in any other case,” he added.

Starmer said anyone who may have details about violence against women and girls has a “duty to come forward” – regardless of status.

Andrew was arrested on Thursday on suspicion of misconduct in public office after it emerged he allegedly forwarded trade docs to his pedophile pal Epstein while serving as a UK trade envoy.

If convicted, he could face life in prison.

Andrew has always denied wrongdoing over his links to Epstein.

Starmer, meanwhile, has faced calls to resign over his decision to appoint Peter Mandelson to a key position as UK ambassador to the US when he was also known to be friends with Epstein, whom he also allegedly passed documents to.
