Table of Contents
(LONDON,February 8,2026) – Labour Party Chief of Staff Matthew McSweeney has resigned,following renewed scrutiny over the appointment of Peter Mandelson to a senior advisory role. Jill Cuthbertson and Vidhya Alakeson will instantly step up as acting chiefs of staff, a senior U.K. official confirmed.
Matthew McSweeney resigned after taking responsibility for advising Labour leader Keir Starmer to appoint Peter Mandelson, whose ties to convicted sex offender Jeffrey Epstein have drawn criticism.
McSweeney announced his resignation Sunday, stating the decision to appoint Mandelson was “wrong” and “damaged our party, our country and trust in politics itself,” according to a statement released earlier that day.
He added that he took “full responsibility” for advising Starmer to make the appointment, saying, “In public life responsibility must be owned when it matters most, not just when it is most convenient.In the circumstances, the only honourable course is to step aside.”
McSweeney’s Role in Labour’s Rise
McSweeney has been a key aide to Starmer throughout his time as Labour Party leader. His work in the late 2010s, first at the Labour Together think tank and then directly for Starmer, was instrumental in shifting the party away from its left flank and ultimately propelling Starmer to the leadership and then Downing Street.
However,McSweeney had faced increasing pressure to resign in recent months. This pressure intensified after the U.S. Department of Justice published additional emails revealing the extent of the relationship between Mandelson and Epstein.
Mandelson was initially appointed to the advisory role in December 2024 but was removed in September last year after initial details of his relationship with Epstein became public. Following the publication of further emails earlier this month, Mandelson resigned his Labour Party membership and his seat in the House of Lords.
Why It Matters
McSweeney’s resignation underscores the political fallout from the ongoing controversy surrounding Peter Mandelson’s association with Jeffrey Epstein. The situation highlights the challenges facing the Labour Party as it seeks to maintain public trust and distance itself from figures linked to serious allegations. The appointment and subsequent handling of Mandelson’s role have become a significant distraction for the party, especially as it prepares for potential future elections.
Why did this happen? Matthew McSweeney resigned because he took responsibility for advising Labour leader Keir starmer to appoint Peter Mandelson, despite Mandelson’s known ties to convicted sex offender Jeffrey Epstein. The publication of further emails detailing the extent of that relationship prompted the resignation.
Who was involved? Key figures include Matthew McSweeney (Labour Chief of Staff, now resigned), Keir Starmer (labour Leader), peter Mandelson (former advisor, resigned Labour membership and House of Lords seat), jill Cuthbertson and Vidhya Alakeson (acting chiefs of staff), and Jeffrey Epstein (convicted sex offender).
What occurred? McSweeney resigned after admitting his advice to appoint Mandelson was a mistake and damaged the Labour Party’s reputation. Mandelson’s ties to Epstein resurfaced with the release of additional emails, leading to his resignation from the Labour Party and the House of Lords. Cuthbertson and Alakeson will now jointly lead the chief of staff role.
How did it end? McSweeney resigned his position, accepting full responsibility. Mandelson had already resigned his advisory role, Labour membership, and House of Lords seat prior to McSweeney’s departure. Cuthbertson and Alakeson are now acting as joint chiefs of staff, providing immediate leadership stability.
