Mandelson resigned from the House of Lords and the Labour Party in February 2026, following his September 2025 removal as UK ambassador to the US, due to his relationship with convicted child sex offender Jeffrey Epstein.
The move came as Keir Starmer said he had handed a dossier to the police after it emerged Mandelson had sent a string of emails to Epstein containing briefings he received as business secretary under Gordon Brown, including action the government was taking to deal with the global financial crisis.
