LONDON (AP) — Peter Mandelson assured the British government it would “never regret” appointing him as U.K. ambassador to the United States, according to documents released on Monday. His guarantee was quickly called into question within months of his appointment.
Over 1,500 pages of documents related to Mandelson’s appointment, a close associate of convicted sex offender Jeffrey Epstein, were made public by the government to comply with a request by lawmakers. These documents illuminate the controversial decision and further exacerbate the challenges facing Prime Minister Keir Starmer.
Among the documents is a note from Mandelson to then Foreign Secretary David Lammy in November 2024, prior to his appointment, pledging that the government would “never regret” his appointment.
Starmer ultimately dismissed Mandelson after nine months when troubling details emerged regarding his friendship with Epstein, leading the prime minister to face intense scrutiny over his leadership.
Alex Burghart, a member of the opposition Conservative Party, remarked that the decision to appoint Mandelson “is a failure that will define this prime minister’s premiership. It is a failure that will be written as his political epitaph,” he added.
Mandelson’s Security Vetting Process
A first set of documents released in March revealed that ministers had been cautioned that Mandelson’s association with Epstein posed a “reputational risk” to the government.
Subsequently, it was found that Mandelson had received approval for the ambassador’s position despite not passing certain security checks, leading to a contentious exchange of blame between Starmer and senior civil servants.
The recently released documents highlight discussions among officials from various departments about Mandelson’s security vetting, which National Security Adviser Jonathan Powell described in earlier released documents as “weirdly rushed.”
One senior Foreign Office official noted that the main concern was “trying to get 101 things done in a very short period of time.”
In an email, Mandelson inquired if he needed to disclose “literally every foreign national I have ever met.” A Foreign Office official then recommended he “send over the handful of names you mentioned. … That will reassure the vetting team that you’ve been comprehensive, even if it’s all quite artificial.”
Details about why Mandelson failed security checks remain unclear. The summary of his vetting process was not included in the released documents, as it is currently part of a police investigation concerning alleged misconduct in public office.
Officials have indicated that ties to Epstein were not the reason for his failure in the vetting. A background report prepared by officials before Mandelson’s appointment, released earlier this year, categorized business ties to Russia and China as areas of concern.
Additionally, no records have been documented regarding the measures, if any, that were taken to mitigate the risks associated with granting Mandelson the ambassador role.
Mandelson has declined to share information from his personal phone with officials, and the documents state that the government “has no further recourse to search the personal devices of Peter Mandelson.”
Mandelson, 72, was briefly detained in February by detectives probing allegations that he shared sensitive government information with Epstein during his tenure as a Cabinet minister over 15 years ago. He was released without imposed bail conditions as investigations continue.
Mandelson was Seen as a Trump Whisperer
Critics assert that Starmer’s decision to appoint Mandelson reflects poor judgment from a prime minister who has faced numerous missteps since steering the center-left Labour Party to a landslide election victory in July 2024.
However, at the time of his appointment, many perceived it as a strategic move to address the unpredictability of the Trump administration.
“I fear that navigating Britain’s interests through the Trump administration will require super-human skills and luck and a massive team effort,” Mandelson stated in his November 2024 note to Lammy.
Mandelson’s background as a former trade chief for the European Union, along with his charm and extensive global network, were regarded as beneficial in negotiating a trade deal with the Trump administration. This approach appeared fruitful when Starmer successfully visited the White House in February 2025, leading to a U.K.-U.S. trade agreement announced that May.
In a letter to Starmer prior to the trip, Mandelson indicated that “America first is the lodestar of his administration,” and that the Trump administration “will play the international system by a different set of rules.”
Mandelson observed in an email that a strong personal bond had developed between the prime minister and the president.
However, Starmer’s relationship with Trump later deteriorated after the U.K. opted not to participate in U.S.-Israeli strikes and various initiatives related to the Iran war. Certain aspects of the trade deal remain incomplete.
Documents Expose Unflattering Comments About Starmer
Revelations concerning Mandelson’s connections to Epstein, uncovered in a significant collection of files published by the U.S. Justice Department in January, prompted renewed questioning of Starmer’s judgment, inspiring some Labour lawmakers and opponents to call for the prime minister’s resignation.
These demands grew stronger following Labour’s significant defeats in local elections in May. A senior Cabinet minister, Wes Streeting, resigned with intentions to challenge Starmer for Labour leadership. Additionally, Greater Manchester Mayor Andy Burnham is running for a seat in Parliament in a special election on June 18 and is also expected to contest Starmer if he wins.
The documents reveal that Mandelson did not always offer unwavering support to Starmer in private discussions, and government ministers expressed their frustrations over Starmer’s evident lack of leadership shortly after he took office.
“Keir is not leading from the front,” Cabinet minister Pat McFadden remarked in a May 2025 WhatsApp exchange with Mandelson.
Mandelson’s assessment described Starmer as lacking “verve,” suggesting that the government needed to operate “dare I say it … in a more Trumpian, risk-taking, and adventurous manner.”
By July, he expressed dismay that the government was “beleaguered and bereft,” stating ministers didn’t have a clear understanding of Starmer’s vision.
“In fact, most of them don’t think Keir knows what he wants,” Mandelson commented.
