Episode Overview

This episode dives into The Guardian’s exclusive revelation that Peter Mandelson, former US Ambassador and a high-profile Starmer appointee, failed security clearance but still assumed his post after the Foreign Office overruled the vetting. The bombshell has triggered national controversy, the resignation of the Foreign Office’s top civil servant, and serious questions about accountability and power in government—just weeks ahead of the May general election. Paul Lewis, Investigations Editor, joins Lucy Hoffman to dissect the findings, public reaction, and deeper issues at stake.

Key Discussion Points & Insights

1. The Revelation and its Fallout

[00:35–01:51]

• Peter Mandelson, Starmer’s pick as US Ambassador, failed UK Security Vetting—normally a formality, even for low-level civil servants.
• The Foreign Office overruled this rare denial (the harshest possible outcome of the vetting process).
• This fact was allegedly withheld from the Prime Minister and surfaced exclusively through The Guardian’s reporting, leading to the abrupt resignation of the Foreign Office’s Permanent Secretary.

"The notion that senior officials could make a decision of this magnitude and not inform a minister, let alone the Prime Minister, I think will strike many people as extraordinary."
—Paul Lewis [00:35]

---

2. Security Vetting Process – What’s at Stake?

[02:12–03:41]

• Standard procedure involves intrusive personal and professional checks, input from security services, and is highly confidential.
• Mandelson’s denial was the third and most severe option; overruled by unelected officials to allow him into this sensitive role.
• Potential risk factors scrutinized include personal and business relations, both domestic and international.

---

3. Political & Parliamentary Implications

[03:41–06:18]

• Mandelson’s forced resignation in September (over Jeffrey Epstein ties) led to a Conservative-led “humble address”: a parliament-backed mandate to release all government documents related to the appointment.
• Exception for documents that could risk national security—these were to go to the Intelligence and Security Committee, but Mandelson’s vetting materials were withheld even from this body.
• Withholding these crucial documents is seen as a potential breach of Parliament's wishes.

"Officials, unelected officials, have been actively thinking about... not disclosing these documents... that relate to what we've revealed to Parliament's approved committee."
—Paul Lewis [05:45]

---

4. Who’s Accountable? Starmer and His Team’s Response

[06:39–08:43]

• Keir Starmer and Chief Secretary Darren Jones claim they were left completely in the dark about the failed vetting.
• Starmer is reportedly “furious,” questioning how a Prime Minister could be kept out of the loop about such a critical security concern.
• Darren Jones attempted to refute The Guardian's findings on the radio, stating the reported parliamentary withholding “is not true.”

"Starmer, he's furious. He says, you know, how on earth could it be that I wasn't informed of this?... If you're ambassador to Washington, you have to handle highly sensitive matters."
—Paul Lewis [07:00]

"We're very confident it is true and I guess we'll see how that plays out."
—Paul Lewis [07:32], regarding The Guardian’s reporting

---

5. Transparency – Did Starmer Move Fast Enough?

[08:02–08:43]

• Starmer claims he found out on Tuesday, yet did not update Parliament during Wednesday’s PMQs session.
• Raises issue of ministerial duty: Should the Prime Minister have corrected the record as soon as possible, especially given the magnitude?

---

6. Wider Lessons: Who Really Holds Power?

[09:12–10:07]

• The ultimate question raised is not just about Starmer or Mandelson, but the deeper issue of where state power truly lies—elected politicians, or unelected officials and security establishment.
• The scandal highlights the blurred lines and tension between political accountability and bureaucratic discretion.

"What does this tell you about where power resides in the state?... Is it the people we elect to government, or is it, you know, officialdom, the state, the national security establishment? For me, that's the heart of this question."
—Paul Lewis [09:24]

Closing Thoughts

Paul Lewis and Lucy Hoffman underscore that while the controversy is right now a political firestorm, the far more lasting impact may be an overdue reckoning with transparency, accountability, and the real lines of power inside the British state. With Parliament, ministers, and the public learning shocking details from The Guardian rather than official sources, the crisis challenges core assumptions about who really governs—and how.

[Paul Lewis]

The notion that senior officials could make a decision of this magnitude and not inform a minister, let alone the Prime Minister, I think will strike many people as extraordinary. That I wasn't told that Peter Mandelson had failed security vetting when he's appointed is staggering. All of this just raises the question about who is in charge. Is it the people we elect to government, to Parliament? Or is it, you know, officialdom, the state, the national security establishment? I mean, for me, that's the heart of this question.

[Lucy Hoffman]

The Guardian has exclusively revealed that Peter Mandelson, the former US Ambassador, failed security clearance. But that was overruled by the Foreign Office and allegedly withheld from the Prime Minister. From the Guardians today. In Focus, this is the latest. With me, Lucy Hoffman. Well, Paul Lewis, our investigations editor, is here, part of the team, the amazing crack squad behind this astonishing scoop that is now on the front page of every single British newspaper. A story about Peter Mandelson, the former US Ambassador, it turns out, failed security clearance. But that failure was overruled by the Foreign Office. Talk to me, Paul, about the reporting that you've uncovered.

[Paul Lewis]

Okay, well, I mean, I guess the key fact, the one that led late last night to the resignation of the Permanent Secretary in the Foreign Office, the key fact that has proven such a huge controversy for the Prime Minister right now, is that after the point at which Peter Mandelson was announced as Starmer's pick for Washington, he had to undergo a security vetting process.

[Lucy Hoffman]

This is at the end of December 2024, wasn't it? And then he was appointed in.

[Paul Lewis]

Exactly. So the Prime Minister announces he's going to be ambassador to the US in December20. By the following month, this security vetting process is underway. Normally, it's just a formality. I mean, I think this may have been lost in some of the reporting. This is a level of vetting that some low ranking civil servants have to go through. Now, what we reported was that vetting process, which is done by an agency called UK Security Vetting, it's a division of the Cabinet Office, vetted Mandelson and it had three options. So it could either give him clearance. That was the first. The second was it could give him clearance with Mitigation, so to mitigate against some of the perceived risk factors. And the third was to entirely deny him clearance. And the decision was to deny him clearance, the third, which is a very rare decision for this agency to make. And then that decision was overruled by officials in the Foreign Office in order for him to take up his post, which he did the following month, which

[Lucy Hoffman]

of course he did. And that is what's caused this huge political controversy, because Downing street are saying that until this week and until the publication of this Guardian exclusive, it was not known that this security vetting had been failed. Before we come on to that, can I just ask what kinds of things they'd be looking into when it comes to security clearance? I mean, it's highly confidential stuff. Right. So I know there are limitations on what we know.

[Paul Lewis]

Yeah. So, I mean, I can talk to you in general terms about what UK security vetting involves. Yeah. And this is what's in the public domain. Okay. So, you know, you go through this process, you, you know, you fill out a questionnaire. You're required to answer sometimes very personal questions about your life, your business relationships, your. Your other relationships with other people around the world, people in your personal life. It can be quite somewhat intrusive, people who have gone through this process say. But it is highly confidential. And there is also input from the security services who would identify any concerns that they have.

[Lucy Hoffman]

So, as you say, this is a highly confidential security check. But Lord Mandelson was, of course, forced to resign from his position as US Ambassador in September of last year. That sort of set various things in motion, not least the humble address that was put in place by the Conservative Party in February. How do these two things interlink?

[Paul Lewis]

As many people watching this will remember, he resigned over disclosures about his relationship with the disgraced sex offender Jeffrey Epstein. And then in the wake of that, there's been, you know, lots of concern in Parliament about the process that led up to his appointment. And in February, there was this thing, you referenced it, the humble address. Now, what that is, it's a parliamentary motion to force the government to disclose what it said were, quote, all papers related to Mandelson's appointment. And that's actually, I think, really important here. And we've been reporting on some of this. So essentially, you know, that's a mandate to government to say anything you've got about Mandelson has to be disclosed. There was an exception made for documents that could prejudice national security or international relations. And those documents, the super sensitive ones, were supposed to go to the Intelligence and Security Committee. However, the documents about Mandelson's vetting, highly sensitive, have not gone to that committee. And according to our reporting, officials have recently been considering whether not to disclose them to the committee. And that would be a, a really significant thing, arguably a breach of Parliament's wishes. You know, I think that has sort of been lost. It's turned to such a huge political story. Right. Keir Starmer, we're like weeks away from the May election. Yeah, I can see that Westminster's latching onto all these different aspects, but for me it's really significant that, you know, officials, unelected officials, have been actively thinking about. And as of when we published our story, no decision had been made not disclosing these documents, the documents at the heart of the story that relate to what we've revealed to Parliament's approved committee.

[Lucy Hoffman]

Yes, it speaks to something about unelected officials making these very, very significant decisions, doesn't it? Sir Ollie Robbins, who was former Permanent Secretary to the Foreign Office, the fcdo, resigned very late last night over this, effectively taking the hit for the Foreign Office's decision not to disclose this or to withhold this information.

[Paul Lewis]

Yeah, taking the hit or was either did it voluntarily or was forced to take.

[Lucy Hoffman]

But what are we hearing from Keir Starmer himself, who's been quizzed about this in Paris this morning, but also his Chief secretary, Darren Jones, who was quizzed about this on the BBC this morning because they're saying they really did not know about the existence of this failed vetting procedure.

[Paul Lewis]

So Starmer and his Chief secretary, Darren Jones, said slightly different things. Starmer, he's furious. He says, you know, how on earth could it be that I wasn't informed of this? And I think lots of people in the country would be asking the same thing. You know, this is the Prime Minister, it's his pick for Washington. You know, if you're ambassador to Washington, you have to handle highly sensitive matters. You look at top secret documents from gchq, the National Security Agency in the us. How could it be that failing vetting is not something that is mentioned? The failure of vetting is not mentioned to the, to the Prime Minister.

[SoFi Personal Loan Announcer]

Yeah.

[Paul Lewis]

Darren Jones was on the radio this morning and he actually shot down our reporting about officials or sought to refute or deny our reporting that officials had been considering withholding this information from Parliament. He said, quote, that's not true. We're very confident it is true and I guess we'll see how that plays out.

[Lucy Hoffman]

So Keir Starmer will be addressing MPs in the Commons on Monday, as we understand from that interview this morning with Darren Jones, he sort of requested the full picture about what's gone on here.

[Paul Lewis]

Yeah, but can I just say on that, a dose of skepticism. Keir Starmer says he found out about this on Tuesday. Yeah, he has an obligation as a minister to correct the record to Parliament as soon as he can. He, the following day on Wednesday, did PMQS and did not correct the record. Now. Now, the argument may be that he was seeking to establish the facts before he fully appraised Parliament of what was going on. But what further facts did he need to establish? He was told, he says, on Tuesday, that Peter Mandelson had failed security vetting. So the question is, should he not have right away, or at the earliest opportunity, told Parliament that that was the

[Lucy Hoffman]

fact, or indeed his own MPs, who, it seems in large numbers found out about this as the Guardian exclusive dropped last night.

[Paul Lewis]

I mean, I'm not a Westminster reporter, right, But I hear from colleagues who are, that, you know, there were government ministers, senior cabinet ministers, who were learning about this for the first time, you know, when they read it in the Guardian on Thursday.

[Lucy Hoffman]

I mean, Paul, obviously this has become a political story in lots of ways, and certainly that's the sort of splash on the front pages of much of the newspaper this morning. But. But there's something bigger at play here and I wonder what you think those questions are as. As head of investigations.

[Paul Lewis]

So, you know, honestly, what's really interesting to me, I'm, you know, not a political hound. You know, lots of people talking about, you know, what does it mean to Starmer, what will it mean for the elections? But really, what. What's curious to me is what does this tell you about where power resides in the state? You know, the notion that senior officials could make a decision of this magnitude and not inform a minister, let alone the Prime Minister, any government minister, I think, will strike many people as extraordinary. So, too will the idea that officials have been considering withholding disclosing information that they've been compelled to reveal by Parliament. I mean, all of this just raises the question about, you know, who is in charge? Is it the people we elect to government, to Parliament, or is it, you know, officialdom, the state, the national security establishment? I mean, for me, that's the heart of this question.

[Lucy Hoffman]

Well, Paul, so much further to go with this story, but thank you to you, Pippa and Henry for such a fantastic piece of reporting and well done on the scoop. Thank you for your time.
