Mandelson Messages Show Sharp Critique of Starmer and Downing Street Culture

The government has published over 1,000 pages of documents concerning Lord Mandelson's appointment as the United Kingdom's ambassador to the United States. The papers include exchanges between Lord Mandelson and ministers, covering advice, news, and pointed criticism of the No 10 operation, Labour members of Parliament, and Prime Minister Keir Starmer himself.

Criticism of No 10 and Keir Starmer

On May 2, 2025, Lord Mandelson wrote to Pat McFadden — then a Cabinet Office minister, now the work and pensions secretary — stating that "Keir lacks verve as does the Cabinet as a whole." In July of that year, messages between the two show Lord Mandelson criticizing advisers in No 10, describing them as good but noting that "they don't work as a team, they are not led and none of them really know what Keir thinks or wants." He added: "In fact most of them don't think Keir knows what he wants."

Later that month, in a further message to McFadden, Lord Mandelson wrote: "I have a feeling that Keir is now consistently going for direction B. His recanting on his immigration speech, on welfare, now Gaza." He continued: "There is definitely a 'let Keir be Keir' trend. This is what Morgan [McSweeney] senses and so it is particularly acute for him. His view from when Keir first stood is that the cycle has been the same, advance/buckle/advance/buckle."

Lord Mandelson later added: "I went in to No 10 after I saw you. It is beleaguered and bereft. It requires complete revamp and infusion of purpose and confidence to get anywhere."

MPs' Concerns and Internal Conversations

In the exchanges, McFadden also described conversations he had with other Labour politicians about the welfare system and public spending in blunt terms. "Every meeting I have is 'who can we tax in order to pay benefits to others'," he wrote to Lord Mandelson. "They're asking the wrong questions." Allies of McFadden pointed out that message was sent before he was in charge of the United Kingdom's benefits regime; he was running the Cabinet Office at the time.

A spokesperson for the work and pensions secretary said: "Pat has fully complied with the Humble Address and handed over all messages. His only contact with Peter Mandelson since he left government has been to urge him to think about the victims in all this and apologise to them."

'Never Regret' Assurances

Lord Mandelson wrote a handwritten note to then-foreign secretary David Lammy stating that the government would "never regret" making him United States ambassador. The letter, dated November 18, 2024, included Lord Mandelson writing: "I just wanted you to know that if you were minded to appoint me I would make sure you never regret it." He said navigating Britain's interests through the Trump administration would "require super-human skills and luck and a massive team effort."

Lord Mandelson added that the role would be the "last thing I do in public life" and a "huge honour", concluding: "So if you are up for it, so am I." He was announced as the United Kingdom's ambassador to the United States on December 20, 2024. Lammy is currently serving as deputy prime minister and justice secretary.

Cabinet Office and Trump Gift Discussions

Lord Mandelson and senior officials discussed commissioning an official government "red box" to give as a gift to United States President Donald Trump. Amid complications in organizing this, the former United States ambassador told No 10 chief of staff Morgan McSweeney that he had "gone tonto" and that the "saga" was "like something out of [TV comedy show the] Thick of It."

Sir Olly Robbins, then the top official at the Foreign Office, said "one of the gifts that would mean the most to the President would be a red dispatch box with the gold crest and lettering mimicking a UK Government Ministerial box but with 'President of the United States' inscribed upon it."

Context

The publication of these documents follows a pattern of internal government communications becoming public through parliamentary mechanisms such as Humble Addresses. Similar disclosures have occurred in past administrations, including the release of messages related to the appointment of other senior diplomatic figures and the handling of sensitive policy decisions.
