Morgan McSweeney, who served as chief of staff to British Prime Minister Keir Starmer, resigned on Sunday. His decision comes amid growing criticism regarding his involvement in the appointment of Peter Mandelson as the United Kingdom’s ambassador to the United States.
In a resignation statement reported by The Guardian, McSweeney admitted that recommending Mandelson for the position was a mistake and took full responsibility for the decision. He described his resignation as the “only honourable course” under the current circumstances. McSweeney expressed that Mandelson’s actions have harmed the party, the nation, and undermined trust in politics.
McSweeney highlighted that the controversy surrounding Mandelson had damaged public trust, urging for a comprehensive reform of the government’s vetting and due-diligence procedure. Despite stepping down, he pledged his ongoing support for Starmer and the Labour government’s initiatives.
“He [Mandelson] has damaged our party, our country, and trust in politics itself,” McSweeney wrote in his statement, acknowledging the difficulty of his decision to resign.
Mandelson’s appointment as ambassador came under scrutiny following the release of emails and documents by the Justice Department in January, which showed that Mandelson maintained contact with Jeffrey Epstein after Epstein’s 2008 conviction of soliciting prostitution, including charges involving a minor.
The Associated Press uncovered documents suggesting that Mandelson may have shared sensitive government information with Epstein during the post-2008 global financial crisis period. Additionally, financial records indicated Epstein had transferred $75,000 to accounts linked to Mandelson or his husband, Reinaldo Avila da Silva, in 2003 and 2004.
Stephen Doughty, a Foreign Office minister, informed the House of Commons on Sept. 11 that Starmer requested Mandelson’s withdrawal as ambassador after discovering discrepancies in Mandelson’s relationship with Epstein at the time of his appointment.
“In particular, Lord Mandelson’s suggestion that Jeffrey Epstein’s first conviction was wrongful and should be challenged is new information,” Doughty commented. “Considering that and being mindful of the victims of Epstein’s atrocious crimes, Lord Mandelson has been withdrawn as ambassador with immediate effect.”
Mandelson resigned from the Labour Party on Feb. 1 following these revelations. Ashley Carnahan, a writer at Fox News Digital, reported the news.
