Sir Philip Barton Unable to Voice Concerns Over Lord Mandelson's US Ambassador Appointment

Former senior official Sir Philip Barton has told MPs that he was afforded no opportunity to express his reservations regarding Lord Mandelson's appointment as the UK's ambassador to the United States in 2024. Speaking to the Foreign Affairs Committee, Sir Philip, who served as the top civil servant in the Foreign Office at the time, revealed that Downing Street did not consult him prior to the decision.

Sir Philip identified Lord Mandelson's connections to convicted sex offender Jeffrey Epstein as a "potentially difficult issue" given Epstein's controversial status in the US. He recounted being "presented with a decision" by Prime Minister Sir Keir Starmer and subsequently "told to get on with it," suggesting a lack of consideration for his concerns.

The former permanent under-secretary at the Foreign, Commonwealth & Development Affairs Office (FCDO) between September 2020 and January 2025, Sir Philip, noted his internal apprehension, stating, "I was worried that this could become a problem in future." He emphasised the absence of any "space or avenue or mechanism for me to put that on the table."

Lord Mandelson's ambassadorship, announced in December 2024, concluded with his dismissal in September of the following year after further details emerged regarding his association with Epstein. Morgan McSweeney, the Prime Minister's former chief of staff, also testified, admitting to a "serious error of judgement" in advising the appointment and apologising to Epstein's victims. McSweeney attributed his advice to a misjudgement of Lord Mandelson's candour regarding the relationship.

Sir Philip distinguished Downing Street's approach to vetting as "uninterested" rather than "dismissive," noting time pressures to complete the process before Donald Trump's January 2025 inauguration. MPs are scheduled to vote on whether to launch a parliamentary investigation into Prime Minister Starmer's statements on the vetting process.
