Andrew Mountbatten Windsor has been asked by Democrats in US Congress to answer questions as part of its investigation into paedophile financier Jeffrey Epstein.

Congressman Robert Garcia wrote to Andrew in a letter addressed to Royal Lodge, Windsor Great Park, which the former prince had agreed to leave.

The panel the congressman sits on does not have the power to compel Andrew to appear in front of them, but intends to ask questions related to information on Epstein's network and associates based on their "longstanding" friendship.

The letter comes after King Charles III stripped Andrew of his HRH style and prince title.

It was signed by 16 members of Congress and requested Andrew sit for a "transcribed interview" in front of the the Committee on Oversight and Government Reform.

"The committee is seeking to uncover the identities of Mr Epstein's co conspirators and enablers and to understand the full extent of his criminal operations," the letter read.

"Well-documented allegations against you, along with your long-standing friendship with Mr Epstein, indicate that you may possess knowledge of his activities relevant to our investigation.

"In the interest of justice for the victims of Jeffrey Epstein, we request that you co-operate with the committee's investigation by sitting for a transcribed interview with the committee."

Buckingham Palace announced last month that Andrew would lose his prince title and leave his Royal Lodge home as his links to Epstein continued to cause controversy.

Andrew Mountbatten Windsor - as he is now to be known - also gave up his other royal titles, including the Duke of York, after more questions and allegations about his private life

In a posthumous memoir published in October, Virginia Giuffre - a prominent accuser of Epstein - repeated allegations that, as a teenager, she had sex with Andrew on three separate occasions. Andrew has always strenuously denied the claims.
