The Threat You Can’t See w/ Ex-Director of GCHQ, Jeremy Fleming (Transcript)

Editor’s Notes: In this insightful episode of The Rest Is Politics: Leading, Alastair Campbell and Rory Stewart interview Sir Jeremy Fleming, the former Director of GCHQ and a long-time veteran of MI5. Sir Jeremy shares his unique “accidental spy” journey and provides a rare, behind-the-scenes look at how the UK’s intelligence agencies have evolved to tackle modern challenges like international terrorism, cyber warfare, and shifting global superpowers. The conversation dives deep into the invisible threats facing national security today, from the complexities of the UK-US relationship to the rising strategic challenges posed by China and Russia. It’s a compelling discussion on the balance between state secrecy, accountability, and the rapid technological changes redefining the world of intelligence. (Feb 9, 2026) 

TRANSCRIPT:

Introduction

ALASTAIR CAMPBELL: Welcome to The Rest of Politics. Leading with me, Alastair Campbell…

RORY STEWART: And with me, Rory Stewart. And we are very excited to have one of my personal heroes, Sir Jeremy Fleming. Jeremy Fleming was the head of GCHQ, which is the Government Signals Intelligence Agency, the equivalent of the National Security Agency in the US. Before that, though, he was a member of the Security Service, MI5, domestic intelligence. We’re very happy to have you. Thank you for coming on.

JEREMY FLEMING: Thank you. It’s nice to be here.

From Hampshire to the Intelligence Services

ALASTAIR CAMPBELL: Starting right at the beginning. So what was your background, and what was it in you that led you down the path that ultimately has defined your life, which is spying and intelligence?

JEREMY FLEMING: Well, I was an accidental spy, and I won’t bore you with all the details. Grew up in Hampshire, single mum, three boys, state schools, comprehensive education, sixth form college, and then university. Read history, mainly because it was five hours a week. And I came out of that thinking, what am I going to do with my life?

Then, after a bit of travelling, I decided I better get a proper qualification. I went into the City, I trained as a chartered accountant, which, whilst the stereotype has been useful for me in avoiding conversations in my career afterwards, actually I really enjoyed that environment.

ALASTAIR CAMPBELL: And do you mean by that sort of training to be boring?

JEREMY FLEMING: Well, it’s a training to put people off asking you extra questions. My mother always used to say that — “I sit next to the most boring person in the world who’s talking about little Johnny, who’s a merchant banker. Excuse merchant bankers. And I have to say, you’re an accountant.” And that usually makes them turn away.

So I trained as an accountant, and I really enjoyed that. I ended up doing some work — this is the end of the 80s, early 90s — some work in government. There was a mini recession. And I found a whole world of challenge and scale that I had no idea about, having worked in the private sector with private sector clients. And I thought, I’m going to stick around here for a bit.

So I applied for a secondment to the Ministry of Defence, and more or less — not quite, but more or less — when I turned up, I found out it was MI5. So careers are about serendipity, if you ask me. And that was one of those sliding door moments. And I went into MI5, and after a year the then Director General said, “Why don’t you stay and do a proper job?” And I was offended, actually.

RORY STEWART: And who was your boss at that time?

JEREMY FLEMING: Well, my boss at that time was Stephen Lander, and before that Stella Rimington. It was around that period. And so I thought, you don’t get this chance very often. And so I suddenly found myself going down the intelligence path.

ALASTAIR CAMPBELL: So you literally were accidental — you had no idea when you applied for the job that you were…

JEREMY FLEMING: When I applied, I had no idea. More or less when I walked in the door, I had little idea. And it was quite a culture shock, if I’m honest with you. Going from very smart offices not far away from here — very modern, open plan even then, people with laptops, technology everywhere — into an environment with yellowing bomb curtains and technology that definitely felt out of date.

ALASTAIR CAMPBELL: It wasn’t James Bond, was it?

JEREMY FLEMING: It wasn’t James Bond, but it was fantastic. People doing important things that mattered. And 25 years later I was Deputy Head of the place, and then went to GCHQ.

The Post-Cold War Era and the Shifting Threat Landscape

RORY STEWART: It’s a very odd time to be joining the Security Service, because the early 90s — the Berlin Wall came down in ’89, the Soviet Union collapsed in the early 90s — and Britain was really scratching its head trying to work out what its intelligence and security services are for. Big Al-Qaeda style terrorism doesn’t really get going till 2001. The Russians are no longer ten feet tall. What was going on during that ten years as people tried to work out where the threats were coming from and what the purpose of the whole thing was?

JEREMY FLEMING: Yes, but remember MI5 is an investigative service, and it exists to disrupt threats to the nation’s national security and protect its economic well-being. And whilst that’s often personified in big state actors — the ten-foot-tall China, Russia, and the list too — it’s often closer to home. It’s about domestic terrorism, it’s about subversion, it’s about espionage.

And at that point, for the first time, it was also about serious crime. So that period actually was a really busy period. It was a transitional period. The Service took on responsibility for intelligence in Northern Ireland and played a fundamental part in the things that you were central to, Alastair. And of course, at that point, we could start to see Islamist-inspired terrorism coming through too. This was when that phenomenon started to take shape.

So it was a transitional period.
