Mandelson messages reveal private Labour criticism of Starmer government

Sir Keir Starmer was due to chair a Cabinet meeting on Tuesday as a new tranche of more than 1,500 pages of Mandelson material pushed private Labour criticism of the government into the open. The documents, which cover Peter Mandelson’s appointment, vetting and communications, do not read like a routine paper trail. They show senior figures around government grappling with a Downing Street operation described by Mandelson as “beleaguered and bereft.”

The clearest political damage lies in the tone of the exchanges. Mandelson reportedly told Pat McFadden that Starmer “lacks verve,” and told Torsten Bell that the government does not do policy “well enough.” Those remarks matter because they go beyond personal irritation. They suggest a circle of insiders who believed Labour was not yet governing with enough force, clarity or discipline, even while it was still trying to settle into power.

The release also exposed the awkward overlap between Labour’s governing project and Mandelson’s controversial appointment as ambassador to the United States. A note from Mandelson to then foreign secretary David Lammy in November 2024 said the government would “never regret” appointing him to Washington. Mandelson then served as UK ambassador to the United States from 10 February 2025 to 11 September 2025 before he was withdrawn after additional emails about his friendship with Jeffrey Epstein emerged. On 11 September 2025, the government said the Prime Minister had asked the Foreign Secretary to withdraw him.

The papers were published after MPs forced disclosure through a Humble Address, underlining how much of the story is about institutional pressure, not just political embarrassment. The material requested by the House of Commons covered communications, vetting and appointment records, and it now places the government’s judgment under a brighter constitutional light. For Labour, that is the harder issue: whether the criticism was simply elite sniping between familiar party veterans, or evidence of a deeper strategic split over how the party is being run.

That question now lands directly on Starmer’s authority. Labour figures have stressed transparency, but the release invites a more searching test of governing discipline. If senior voices inside the system were already warning that policy was not being handled well enough, then the controversy is no longer only about Mandelson’s appointment. It is about whether Number 10 can command confidence inside its own ranks while voters judge the government’s early performance.
