Mandelson files: What you need to know
Mandelson Files: A Comprehensive Overview
The government has made available a substantial collection of over 1,000 pages detailing Lord Mandelson’s tenure as the British ambassador to the United States. This disclosure follows a parliamentary vote compelling the release of records concerning his appointment, which ended last year after it emerged that he had extensive ties to Jeffrey Epstein, the late convicted sex offender.
Compiled into three separate volumes, the release required an expenditure exceeding £1 million. It represents a significant expansion of the initial batch of files published in March, being more than ten times larger. As Westminster officials continue to analyze the contents, the following key insights have emerged:
Inside the Machinery of Government
The released materials offer an unprecedented look into government operations, comprising hundreds of internal emails and numerous WhatsApp exchanges between Lord Mandelson and various ministers across 56 distinct conversations.
These records reveal initial uncertainty among officials regarding whether Mandelson required "developed vetting" for his security clearance, a step they ultimately deemed necessary. Other communications expose the urgency surrounding the vetting process, with one official noting "quite a bit of senior interest" in the speed of its completion.
The files also outline diplomatic strategies aimed at courting US President Donald Trump, including a proposed gift of a mock red box—the traditional briefcase of British ministers—which was never actually presented.
Furthermore, the messages highlight private grievances held by ministers within Sir Keir Starmer’s administration. In one instance, then-cabinet minister Pat McFadden expressed irritation that meetings were overly focused on determining "who can we tax in order to pay benefits." Similarly, Work and Pensions Minister Torsten Bell characterized the governmental process as "messy," complaining that staff members often assumed policy accuracy was someone else’s responsibility.
Mandelson’s Assessment of Labour
The correspondence provides insight into Lord Mandelson’s, a prominent figure from the New Labour era, perspective on the Starmer government following Labour’s 2024 return to power.
In a May 2025 exchange with McFadden, Mandelson stated that "Keir lacks verve as does the Cabinet as a whole." By July 2025, he described the operation at No 10 as "beleaguered and bereft," arguing it required a "complete revamp." He suggested that the team surrounding the prime minister was unsure of Sir Keir’s intentions, adding, "In fact most of them don't think Keir knows what he wants."
Additionally, the peer shared his opinions on specific policies, such as the now-enacted plan to apply VAT to private school fees, which he labeled "probably unwise."
Extent of Redactions
Approximately 300 documents were submitted to Parliament’s Intelligence and Security Committee to determine what information should be redacted. The government noted that some materials were declassified for publication. While the motion permitting the release allowed for blacking out content related to national security or diplomatic relations, other information was withheld for different reasons.
These include the identities of junior civil servants and data deemed "commercially sensitive" by the government. Consequently, deciphering certain sections is difficult, as key passages or entire messages have been redacted.
The government attempted to obtain information from Lord Mandelson’s personal phone through his legal representatives, but the peer "declined to comply." The government lacks the authority to compel him to do so. Furthermore, some documents have been withheld at the request of the Metropolitan Police, who are currently investigating the peer regarding allegations of misconduct in public office.
