The Vetting Disaster That Won't Die—And What It Says About Starmer's Control

---

Lord Mandelson didn’t pass his security vetting. The Prime Minister claims he wasn’t told. And now we’re supposed to believe that one of the most powerful political operators in modern British history—a man who’s served as Business Secretary, Northern Ireland Secretary, and EU Trade Commissioner—slipped into the US ambassador role despite failing initial checks, and nobody thought to mention it to the guy who hired him.

I’ve covered enough Westminster scandals to know when something doesn’t add up. This doesn’t just not add up. It insults the concept of addition.

Let’s start with what we actually know. Lord Mandelson was given a security clearance despite concerns being raised during vetting checks. That’s not me editorializing—that’s the reporting. The PM is said to be “absolutely furious” over how it was handled. And now there are calls for Starmer’s resignation because he apparently wasn’t informed that the person he appointed to one of Britain’s most sensitive diplomatic posts had failed to clear initial security scrutiny.

The timeline matters here. These checks happen before people take up positions, not after. They’re supposed to be gatekeeping mechanisms. The whole point of vetting is that if someone doesn’t pass, they don’t get the job. Except in this case, someone didn’t pass and got the job anyway. And the person who made that call didn’t tell his own Prime Minister.

The Competence Question Nobody’s Asking Loudly Enough

Here’s what bothers me most: this isn’t about Mandelson. Mandelson’s been through rougher patches than this. The story here is about whether the current government knows what it’s doing with basic administrative procedures.

A security clearance for a US ambassador is not obscure. It’s not a technicality. It’s foundational. You can’t do that job if you’re a security risk. So either someone decided the concerns weren’t serious enough to block the appointment, or someone decided to hide the concerns from the Prime Minister, or someone simply lost the paperwork in the shuffle. None of those options are reassuring.

Compare this to how governments handled similar situations in, say, 2010-2015 when David Cameron’s administration took office. Yes, there were missteps. But there was generally a sense that you didn’t just improvise around security checks. They’re bureaucratic for a reason—the kind of reason that exists because something bad happened once.

Starmer came into office promising competence. Competence. That was the selling point against years of Conservative chaos. And within months, his government’s handling of a straightforward vetting process has become a resignation-level crisis. The irony’s so thick you could spread it on toast.

The real villain in this story isn’t Mandelson. It’s institutional sloppiness. Someone, somewhere in the machinery decided that initial vetting concerns weren’t disqualifying. Maybe they were wrong. Maybe they were right and just terrible at communicating their reasoning. Either way, the fact that the Prime Minister didn’t know his own ambassador hadn’t passed checks suggests the machinery isn’t working the way people thought it was.

Meanwhile, Watch What Everyone Else Is Doing

There’s something almost darkly funny happening elsewhere in government while this fire burns. The AI minister—the Science, Innovation and Technology Secretary—unveiled a £500m fund to boost British AI firms this week. That’s good policy, probably necessary. But then she said she doesn’t use AI at work.

Not “I’m cautious about AI.” Not “I’m still evaluating it.” Doesn’t use it. At all.

I don’t think she’s lying. I think she genuinely doesn’t use it, which tells you something interesting about how much of government still operates. We’ve got a minister overseeing an entire sector, pushing half a billion pounds into it, and she’s running her office like it’s 2015. That’s not necessarily wrong—maybe there are good reasons to be skeptical. But it’s worth noting the disconnect between the ambition and the actual adoption inside the building making the policy.

It’s a small thing compared to the Mandelson mess, but it fits a pattern I’m seeing: a government that makes strong policy announcements while its internal operations stay remarkably unchanged.

The Other Crises They’re Not Fighting

Three thousand miles away, there are genuinely consequential things happening that don’t require a resignation inquiry to matter.

Oil prices just fell sharply because Iran said the Strait of Hormuz is open for business again. That’s good news on the surface. It’s terrible news if you’re tracking energy security, because it means we got lucky this time—Iran backed down, tensions eased, oil flows resumed. But analysts are already noting that “it’s not clear how quickly the oil industry in the Persian Gulf would be able to get back to normal.”

That sentence is doing a lot of work. It’s saying: we dodged something scary, and we’re not even sure what the recovery looks like yet.

Trump’s administration is meanwhile being urged to act on what experts call “Pickaxe Mountain”—a site in Iran that’s apparently so hardened that conventional airstrikes might not work. Some experts are openly saying this illustrates the impossibility of relying on military force alone to prevent Iran from acquiring nuclear capability. That’s not partisan framing. That’s people with security expertise admitting that a policy option everyone’s been discussing might not actually be workable.

And at home, the Supreme Court just sided with oil companies in Louisiana, clearing the way for environmental lawsuits to move out of state courts into federal venues. Friendlier venues. That’s a small thing until you realize it means environmental litigation is about to get a lot harder to win in certain places.

None of this will make the evening news as long as Mandelson’s vetting document is still burning.

What I Actually Think

Here’s my read: Starmer survives this, but something in his political armor gets permanently dented.

He came in as the serious guy. The competence play. The “we’ll run the trains on time” option after years of Westminster theatre. And now there’s a story about basic administrative failures that reached the level of prime ministerial fury before anyone thought to tell him what was going on. That’s not a Mandelson problem. That’s a “how does your government actually work” problem.

The resignation calls will fade. Mandelson’s diplomatic skills mean he probably does fine in Washington despite this. The civil service will shuffle some people around and everyone will move on.

But voters will remember that the competence government couldn’t competently handle a security clearance. That’ll sit in their heads the next time Starmer claims to have fixed something or promises that his administration will execute a plan properly. Credibility doesn’t come back as fast as it leaves.

What I’m Watching

• Whether the PM’s chief of staff or someone equivalent takes the fall by mid-March. If Starmer fires someone for this, it signals he’s cleaning house. If nobody takes responsibility, it signals the problem’s deeper than one bad process.

• How the US State Department treats Mandelson going forward. Watch whether American officials treat him as slightly tainted or perfectly fine. Their posture tells you whether this was a real security concern or bureaucratic theatre.

• Any statement from the outgoing security vetting authorities about why Mandelson was cleared despite initial concerns. If no explanation ever emerges, the cover-up becomes the real story.

• Whether Kendall’s AI fund actually gets used by government departments by Q4 2025. If the minister who oversees AI doesn’t use it, you’ll have a clear metric for whether this government can even implement its own policies.
