Keir Starmer, the UK Prime Minister, has intensified calls for Andrew Mountbatten-Windsor to provide testimony in the ongoing US congressional investigation into Jeffrey Epstein. Speaking at the G20 summit, Starmer underscored the necessity for individuals with pertinent information on child sexual offences to come forward, though he acknowledged that the decision ultimately rests with the former prince.

Mountbatten-Windsor, who was stripped of his royal titles last month, has yet to respond to an interview request from the US House oversight committee. The committee, which is probing Epstein's activities, had set a deadline of November 20 for his response. Two Democratic members, Robert Garcia and Suhas Subramanyam, expressed their frustration at his silence, stating it "speaks volumes" and vowed to continue their work with or without his cooperation.

The investigation is part of a broader effort to hold accountable those involved in Epstein's network, a mission complicated by the inability to compel foreign nationals to testify. The Epstein Files Transparency Act, signed into law by former President Donald Trump, aims to increase transparency by requiring the release of government documents related to Epstein's case.

Despite the mounting pressure, the committee's Republican chair, James Comer, has not indicated whether he will pursue a subpoena for Mountbatten-Windsor. The former prince, who denies any wrongdoing, could avoid legal repercussions by not traveling to the US.
