Morgan McSweeney, the Chief of Staff to the Prime Minister, has resigned following significant political backlash regarding the controversial appointment of Peter Mandelson as the US Ambassador. This turmoil was ignited after new documents emerged from Jeffrey Epstein's files, implying that Mandelson had shared confidential ministerial information with the convicted sex offender during his term in office.

The controversy surrounding Mandelson's appointment had been contentious, culminating in McSweeney facing criticism from numerous Labour MPs who charged him with responsibility for the fateful decision. Although Mandelson's tenure had ended last September, the revelations from the Epstein archives revived public and political scrutiny over the implications of his past associations and the integrity of the Labour Party.

In his resignation statement, McSweeney admitted that the decision to appoint Mandelson was a mistake, which he claimed has harmed the party and the country. This fallout highlights the ongoing tensions within British political circles regarding past associations with Epstein and raises questions about accountability and governance in the Labour Party as it strives to maintain public trust amidst growing scrutiny.
