Details are emerging regarding a significant internal dispute surrounding the appointment of Lord Mandelson as the UK’s US ambassador. The controversy centers on concerns raised by Sir Philip Barton, then Permanent Under Secretary at the Foreign Office, regarding vetting procedures and potential conflicts of interest.

Internal Opposition to the Appointment

Despite reservations from Sir Philip Barton, Downing Street and the Cabinet Office actively pushed for Lord Mandelson’s appointment to the crucial diplomatic post. Barton, a seasoned civil servant who has served four prime ministers, resisted the move due to concerns about Mandelson’s past commercial dealings with Chinese and Russian companies through Global Counsel.

Concerns Over Past Associations

Barton also expressed concerns regarding Mandelson’s association with convicted sex offender Jeffrey Epstein. The Cabinet Office attempted to bypass standard security vetting procedures, arguing Mandelson’s status as a former Cabinet minister, peer, and Privy Councillor warranted an exception. This effort was led by Pat McFadden, then Chancellor of the Duchy of Lancaster, who has a close personal relationship with Mandelson.

Efforts to Retain Previous Ambassador

Barton also advocated for the retention of Dame Karen Pierce, the outgoing US ambassador, who had established strong relationships with both the Biden administration and the incoming Trump team. Reports indicate that the Trump transition team itself lobbied for Pierce to remain in her position, expressing dismay at the prospect of Mandelson taking over.

Allegations of Direct Pressure

The pressure to approve Mandelson’s appointment was reportedly intense. Allegations have surfaced that Morgan McSweeney, then chief of staff to Sir Keir Starmer, directly pressured Barton to approve the appointment, reportedly saying, “just f*****g approve it,” a claim McSweeney denies.

Barton's Departure and Upcoming Testimony

Even after vetting began, the process was marked by political interference, with Barton’s concerns repeatedly dismissed. He ultimately agreed to an early retirement, receiving a compensation package of £262,185. Sir Philip Barton is scheduled to testify before the Foreign Affairs select committee.

Downing Street Anxiety

The upcoming testimony has created considerable anxiety within Downing Street. Following Sir Olly Robbins’s critical testimony regarding the vetting process, Barton is expected to provide further damaging details about the events surrounding Mandelson’s appointment. He is anticipated to expose the extent of the Cabinet Office’s efforts to circumvent standard procedures and the political pressure exerted to secure Mandelson’s position.

The revelations raise serious questions about the integrity of the appointment process and the influence of personal connections within the government.
