British police have expanded their review of Jeffrey Epstein’s links to the UK, confirming for the first time they are assessing claims that he used private flights into British airports to traffic women.

The move follows comments by former prime minister Gordon Brown, who cited newly released U.S. files alleging Epstein flew women into Stansted Airport.

Four forces — including Essex Police, Thames Valley Police, Surrey Police and the Metropolitan Police — are now assessing allegations, including separate claims involving Prince Andrew, who denies wrongdoing.

Authorities are reviewing whether the claims warrant full criminal investigations, with some sources warning more allegations may emerge following the release of extensive U.S. Justice Department files, The Guardian has reported.

Stansted Airport said private jet operations and immigration checks are handled independently and in line with regulations.
