Mandelson criticised Starmer’s lack of ‘verve’ and tendency to buckle under pressure

Peter Mandelson exchanged WhatsApp messages with a senior cabinet minister criticising Keir Starmer’s lack of “verve” and tendency to buckle under pressure, suggesting the prime minister should behave in a more “Trumpian” fashion.

The former US ambassador said Number 10 was “beleaguered and bereft” and that the public were “crying out for leadership”.

In other exchanges included in a major release of files on Monday, he accused the former prime minister Gordon Brown of trying to undermine Starmer to the advantage of the then deputy PM, Angela Rayner – and suggested the former health secretary Wes Streeting was “hysterical” over Gaza and having a “mid-life crisis”.

The exchanges with the work and pensions secretary, Pat McFadden, show extensive discussions of the party’s strategy, including Mandelson’s view that businesses were losing confidence in the UK economy.

The WhatsApps are part of a vast tranche of data that MPs voted to release in February relating to Mandelson’s appointment as US ambassador including texts with ministers and senior officials.

Mandelson was sacked from the role in the autumn after new disclosures about the closeness of his friendship with the late sex offender Jeffery Epstein.

Some of the messages appear to show Mandelson going well beyond his brief as ambassador, instead providing UK political advice. The first criticism in the Mandelson-McFadden exchanges comes after Rachel Reeves’s spring statement last year, when the government was forced into additional proposed welfare cuts because of downgrades in the Office for Budget Responsibility’s forecasts.

“I am very worried about the economy. Confidence is being lost,” Mandelson texts, which McFadden says there is a “pattern we must get out of”.

The pair also had long exchanges in the aftermath of the May 2025 local elections and the loss of the Runcorn byelection to Reform. Mandelson said that the prime minister’s then chief of staff, Morgan McSweeney, had been “confident” about winning Runcorn.

“The problem is the government doesn’t give a sense of crusading to turn round and change Britain. That’s what I mean by panache, verve,” he wrote.

“It does start right from the top, I am afraid, but you must all contribute more to it by breaking out of the Whitehall system and mould and appearing less like business as usual conventional ministers and, dare I say it, behaving in a more Trumpian risk-taking and dare-devil way.

“At the moment ministers seem to be looking more to the Whitehall machine and the party base than to the public who are crying out for leadership.”

In another exchange two days later, Mandelson said Brown was trying to undermine Starmer – but suggested he knew key figures on the soft left such as Rayner and Ed Miliband were not serious challengers to Starmer.
