PM's chief aide McSweeney quits over Mandelson row

Morgan McSweeney, the influential chief of staff to Prime Minister Sir Keir Starmer, resigned from his position at 10 Downing Street on Friday following a internal fallout over the controversial appointment of Lord Mandelson as the UK’s ambassador to the United States. The departure marks a significant shift in the British government's inner circle, as McSweeney stated he takes 'full responsibility' for the advice that led the Prime Minister to select the New Labour veteran for the crucial diplomatic post in Washington. This move was intended to stabilize transatlantic relations ahead of a new US administration but instead sparked intense friction within the Labour Party's senior leadership and civil service ranks. McSweeney, often credited as the architect behind Labour’s landslide election victory, had been a central figure in shaping the government's strategic direction since the party took office. The decision to recommend Peter Mandelson—a figure synonymous with the Tony Blair era—was seen as an attempt to leverage Mandelson’s deep international connections. However, the proposal reportedly met with significant pushback from various factions within the party who viewed the appointment as backward-looking and potentially divisive. The internal row escalated in recent days, making McSweeney’s position untenable as the administration faced accusations of poor judgment and lack of internal cohesion. In his resignation statement, McSweeney emphasized that his exit was necessary to protect the integrity of the Prime Minister’s office and to ensure that the government could move forward without the distraction of personnel disputes. His departure is expected to trigger a wider reshuffle of Downing Street's advisory team as Sir Keir Starmer seeks to reset his administration's focus on domestic policy and international diplomacy. The fallout highlights the delicate balancing act the new government faces in filling high-profile diplomatic roles while maintaining unity among its key strategists and political allies.
