What's New

The second batch of Mandelson files dropped Monday, with more than 1,000 pages, bringing the total document release to nearly 1,500 pages across three volumes, according to BBC News. That's more than ten times the size of the first batch released in March.

Total cost to assemble: over £1 million of taxpayer money.

The release covers internal government emails, official communications, and 56 separate WhatsApp conversations between Lord Peter Mandelson and senior ministers. The documents were forced out by Parliament through a mechanism called a Humble Address — meaning the government didn't volunteer this. MPs dragged it out of them.

What the Files Actually Say

The headline revelations aren't about Epstein. They're about how Mandelson privately viewed the man who appointed him.

On May 2, 2025, Mandelson wrote to then-Cabinet Office minister Pat McFadden: "Keir lacks verve as does the Cabinet as a whole." According to BBC News, he followed that up in July with a message saying No. 10 advisers "don't work as a team, they are not led and none of them really know what Keir thinks or wants."

Then he went further. Per the Evening Standard, Mandelson told McFadden: "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."

He also told McFadden that Chancellor Rachel Reeves couldn't explain where economic growth would come from.

These weren't opposition attacks. This was the man Starmer personally chose as his top diplomat in Washington, writing privately to a Cabinet minister.

McFadden Gets Burned Too

Mandelson isn't the only one whose private words are now public. Work and Pensions Secretary Pat McFadden — the person Mandelson was messaging — got exposed too.

According to BBC News, McFadden wrote to Mandelson: "Every meeting I have is 'who can we tax in order to pay benefits to others.' They're asking the wrong questions."

The Conservatives have already seized on that line. It won't go away.

The Document Everyone Wants Is Still Missing

The key vetting summary document — the one that would explain how Mandelson failed security vetting but got the Washington job anyway — is NOT in these files. According to The Independent, the Metropolitan Police warned that releasing it could jeopardize an active criminal investigation.

Scotland Yard launched that investigation earlier this year into allegations of misconduct in a public office — specifically that Mandelson shared sensitive government information with Jeffrey Epstein during his time as Business Secretary in 2009. He was arrested in February, released under investigation, and denies wrongdoing.

The document that explains the most is the one being withheld for the most serious reason: an active criminal probe.

Parliament's own intelligence watchdog, the Intelligence and Security Committee (ISC), previously accused the government of withholding documents too broadly. ISC chairman Lord Beamish said ministers should seek Parliament's permission before excluding information on non-security grounds. Per The Independent, the ISC suggested redactions were "being applied far too broadly."

The government said it's "committed to complying with the humble address in full." That claim is hard to square with the fact that the single most important document isn't in there.

What Else Got Buried

Also in the files: a scrapped plan to present President Donald Trump with a mock red box — the iconic briefcase British ministers carry — as a diplomatic gesture to win him over. According to BBC News, it "never saw the light of day."

Mandelson also declined to comply with a request to hand over his own devices, according to the Evening Standard. That's a former senior diplomat refusing to cooperate with a document request tied to his own appointment.

What the Media Is Getting Wrong

BBC's political editor Chris Mason wrote that "diminishing returns have kicked in" on the Mandelson story — suggesting public appetite for new revelations is fading. That framing conveniently serves the government's interest in moving on.

The missing vetting document isn't old news. It's the center of an active Metropolitan Police criminal investigation. The story isn't about WhatsApp gossip. It's about whether a man with known links to Epstein, China, Russia, and Israel bypassed security clearance to become Britain's ambassador to Washington — and whether anyone is going to be held accountable for that.

The £1 million document dump is a distraction if the one document that matters most still isn't public.

What This Means

For regular British taxpayers: your government spent over £1 million releasing documents that confirm their ambassador thought the Prime Minister lacked direction — while the document explaining how that ambassador got the job over security objections stays locked in a police evidence file.

Starmer appointed Mandelson. Mandelson privately called Starmer's operation "beleaguered and bereft." Mandelson then got sacked after his Epstein ties became public. And now Scotland Yard is investigating.

That's the whole story. It was never really about WhatsApp messages.
