Let’s be real for a second. If you’re the most powerful advisor in the country, carrying a government-issued phone packed with sensitive WhatsApps about the next UK ambassador to the US, and that phone gets snatched in broad daylight, you’d expect the police to do more than just hand you a crime reference number and a "better luck next time" shrug.
Yet, that’s exactly what happened to Morgan McSweeney, Keir Starmer’s former chief of staff. In October 2025, a guy on an electric bike allegedly grabbed McSweeney's phone while he was walking in central London. The Metropolitan Police looked at the case, decided there were "no realistic lines of enquiry," and shut the file. Case closed.
Except it isn't. Now, months later, as Parliament demands to see the "Mandelson files"—a treasure trove of messages regarding Peter Mandelson’s controversial (and now defunct) appointment as ambassador—the Met has suddenly realized they "accidentally" wrote down the wrong address for the crime. Instead of Belgrave Street in East London, it was actually Belgrave Road in Pimlico.
Wes Streeting has been sent out to the airwaves to tell us all to stop being conspiracy theorists. But when the missing phone contains the very evidence a parliamentary motion is demanding, the "cock-up" explanation starts to feel a bit thin.
The convenient timing of a street robbery
The timeline here is enough to make any political skeptic's head spin. By mid-October 2025, Labour officials were already sweating. They knew the Conservatives were planning a "humble address"—a high-powered parliamentary demand—to force the release of every single message between McSweeney and Mandelson.
On October 20, just days after these internal alarms started ringing, McSweeney’s phone vanishes.
Streeting tells us that McSweeney couldn't have known how "unprecedented" the demand for messages would be. Honestly, that's hard to swallow. Anyone at the top of a government knows that when a scandal involving a figure like Peter Mandelson starts brewing, the digital trail is the first thing people look for.
The theft happened while McSweeney was returning from a restaurant. He reportedly gave chase but couldn't keep up with the electric bike. It’s a classic London crime, but the stakes here aren't just a £1,200 piece of hardware. It’s the data.
Why the Met Police U-turn matters
The Met’s initial refusal to investigate looks bad. They claimed they were "too busy." This is a government-issued device belonging to the Prime Minister’s right-hand man. Usually, that gets a bit more attention than your average Saturday night mugging.
The sudden discovery of a "clerical error" regarding the address is even weirder. They say they recorded it in E1 (Stepney/Wapping area) when it actually happened in Pimlico. Because of this "mix-up," they didn't check the right CCTV. Now they're going back to look.
Here is the problem. CCTV in London doesn't last forever. Most systems overwrite footage within 30 days. By the time the Met "realized" their mistake in March 2026, those tapes were likely wiped months ago.
- The Address Error: Entering "Street" instead of "Road" sounds like a small mistake, but in police work, it’s the difference between looking for a suspect in the East End or around the corner from Tate Britain.
- The Vanishing Evidence: If the phone is gone, and the cloud backups are "incomplete" or "unavailable" for the specific period requested, the Mandelson files effectively have a giant, McSweeney-shaped hole in them.
Streeting versus the skeptics
Wes Streeting is currently the government’s designated "human shield." He’s been all over Times Radio and the morning shows trying to dampen the flames. His argument is basically: "We're too disorganized to pull off a conspiracy this sophisticated."
He calls it a "cock-up." He points out that McSweeney reported it immediately and got a new phone with the same number the next day. But the number doesn't matter; the local storage on the device does. If those WhatsApp messages weren't backed up to a government server—which they should have been, but often aren't for "security reasons"—they are effectively deleted.
Streeting himself already released his own messages with Mandelson. Those leaks showed him being pretty brutal about Starmer’s leadership. By being transparent himself, he’s trying to buy credibility for his colleagues. It's a smart play, but it doesn't explain why the Met treated the Chief of Staff like a regular guy who lost his Nokia in 2004.
What this means for the Mandelson files
The "Mandelson files" are the ultimate headache for this administration. Peter Mandelson’s ties to Jeffrey Epstein, which came to light (again) following his arrest in February 2026 for misconduct in public office, have turned his short-lived ambassadorship into a toxic waste site for the Labour party.
The Tories are smells-blood-in-the-water levels of excited. They've already accused the government of a cover-up. If the Met's "re-investigation" comes up empty—which it almost certainly will, given the time elapsed—it leaves the public with two choices:
- Believe that the most powerful man in No. 10 is so unlucky that he lost his phone at the exact moment it became a legal liability.
- Believe that the Metropolitan Police and the Cabinet Office are quietly letting a "street crime" solve a very big political problem.
What you should watch for next
This story isn't going away. The Met has released a transcript of the 999 call to prove McSweeney didn't pull rank or demand special treatment. Ironically, the fact that he didn't mention he worked for the PM is now being used by the police to justify why they didn't try harder to find it.
If you're following this, keep an eye on the Information Commissioner’s Office. They usually don't take "my phone was stolen" as a valid excuse for missing data in a freedom of information or parliamentary request.
You should also look for whether the Cabinet Office can produce the server-side logs of these messages. If the "government phone" was synced to a secure cloud, the theft shouldn't matter. If they suddenly claim the sync failed, then you’ll know exactly what kind of game is being played.
Check the official Met Police news feed or the Hansard records for the next session of PMQs. The pressure on the Home Secretary to explain the Met's incompetence—or convenient "clerical errors"—is only going to get heavier from here.
