The King’s brother should share any information he has about Jeffrey Epstein with US authorities, Sir Keir Starmer has suggested.

The Prime Minister said that while any decision was up to Andrew Mountbatten-Windsor, his “general position is if you have relevant information you should be prepared to share it”.

Andrew is under pressure to share what he knew about Epstein with a US Congressional committee, which is investigating the scale of Epstein’s offending and who else was involved.

The King’s younger brother has always denied all wrongdoing.

Asked whether the former duke should help in “any way he can” by reporters on the way to the G20 summit in South Africa, the Prime Minister said: “I don’t comment on his particular case.

“But as a general principle I’ve held for a very long time is that anybody who has got relevant information in relation to these kind of cases should give that evidence to those that need it.

“That would be my general position on this.”

Asked if that would apply to Andrew – who was called Prince Andrew until that title was stripped by the King – the PM said: “In the end, that will be a decision for him.

“But my general position is if you have relevant information, you should be prepared to share it.”

The intervention comes after Democratic members of the US House Committee on Oversight and Government Reform wrote to Andrew on November 6.

They asked the former duke to sit for a transcribed interview about his long-standing friendship with Epstein.

The letter, signed by 16 lawmakers including Congressman Robert Garcia and Congressman Suhas Subramanyam, set a response deadline of November 20.

LATEST ROYAL DEVELOPMENTS

• Andrew misses US Congress deadline requesting he testify about his links to Jeffrey Epstein
• Jeffrey Epstein survivor calls for Andrew Mountbatten-Windsor
• Labour declare ‘no need’ to legislate the removal of Andrew

However, Andrew missed the deadline to respond to the US Congress about his links to the late paedophile.

US lawmakers could not compel Andrew’s testimony because he is a foreign national, but they did urge him to cooperate voluntarily.

Mr Subramanyam clarified that the former prince did not reply. Andrew’s links to Epstein have been scrutinised for years.

He was photographed with Epstein in 2010 and is named in flight logs and other documents.

In 2022, he reached an out-of-court settlement with Virginia Giuffre after denying her allegation that Epstein trafficked her to him when she was 17.

Epstein died in custody in 2019.

The Oversight inquiry has recently obtained thousands of emails and records from Epstein’s estate as part of a wider push in Washington to identify enablers and assess how authorities handled the case.

The committee says cooperation from high-profile associates is central to that work.
