Hosts: David McCloskey and Gordon Corera

Introduction

In this compelling episode of The Rest Is Classified, hosts David McCloskey and Gordon Corera delve into an exclusive interview with Eliza Manningham-Buller, the former head of MI5. Manningham-Buller provides an insider’s perspective on pivotal events in modern British intelligence, including her encounters with Vladimir Putin, the aftermath of the 7/7 bombings in London, and the intricate connections to Al-Qaeda.

Meeting with Vladimir Putin

The discussion opens with Manningham-Buller recounting her face-to-face meeting with Vladimir Putin in the immediate aftermath of the 7/7 bombings.

• [03:49] Eliza Manningham-Buller: “He was clearly hostile to me and said something like, it's the duty of people like you to stand between the terrorist and their victim. And you failed. So it wasn't a very successful meeting.”

Manningham-Buller describes Putin as having “sinister looking eyes” ([04:27]), and reflects on the strained nature of their encounter. She highlights the tension and the accusatory stance Putin took during their briefing on the preliminary state of the investigation.

Aftermath of the 7/7 Bombings

The conversation shifts to the immediate consequences of the 7/7 attacks and the subsequent actions taken by intelligence agencies.

• [04:47] Interviewer: "But it's amazing, isn't it? A year after basically coming down, talking to the Prime Minister, meeting you in a Cobra, he's ordering polonium attack on the streets of London, involved in it."

Manningham-Buller speculates on the audacity and risks associated with such attacks:

• [04:56] “I always assume, I have no evidence of this, that it was such a risky thing to do in some respects, that I think they must have done it somewhere else, had it not been noticed, so that they could say it's safe to do this in London.”

She further considers the possibility that similar attacks could have been orchestrated elsewhere to avoid detection, reflecting on the strategic calculations behind high-profile terrorist acts.

Reflections on the 21/7 Plot

The hosts and Manningham-Buller discuss the attempted 21/7 bombing, which employed similar explosive devices to those used in the 7/7 attacks.

• [05:54] Manningham-Buller shares her sentiments: “Well, first of all, you always know you'll never prevent everything. I think the number that are prevented where it's been made public vastly outweighs those which are not.”

She expresses a sense of gloom surrounding the plot, acknowledging that while no lives were lost, a repeated occurrence of such attempts would have severely strained MI5's capabilities.

• [06:41] Interviewer: “Fortunate, but it must have been a thought inside MI5. What if this is going to happen every two weeks?”

• [06:47] Eliza Manningham-Buller: “Exactly. And we were quite relieved when two weeks later in August, the date passed without anything happening.”

Linkages to Al-Qaeda

The episode explores the broader connections between these terrorist plots and Al-Qaeda’s influence.

• [07:00] Manningham-Buller notes, "Al Qaeda is an inspiration. It doesn't have to direct things. I mean, the fact that Mohamed Sadiq Khan went back to Afghanistan, clearly there was some connection there."

She underscores the autonomous nature of various terrorist cells, indicating that while direct orders from Al-Qaeda might not always be present, the ideological inspiration remains a driving force.

Impact of the Iraq War on Radicalization

A significant portion of the interview addresses the ramifications of the Iraq War on global terrorism and radicalization.

• [07:26] Interviewer: “I think you've spoken previously that you think the Iraq war did contribute to that radicalisation and that you'd said that before the war as well.”

Manningham-Buller concurs, linking the Iraq conflict to increased terrorist activity:

• [07:33] “I think at MI5, I think that before the war the JRC had, the government, the Joint Intelligence Committee, that there'd be a likely increase in terrorism. [...] We know that it was a contributor because of the video wills we recovered, including the following year, the airlines plot Operation Avert, where people particularly instanced this. And yes, it was a contributor.”

She reflects on the challenges faced by intelligence agencies in anticipating and mitigating the surge in terrorism post-conflict.

Legacy and Transformation of MI5

The conversation concludes with insights into how the events discussed have shaped MI5’s evolution.

• [08:41] Eliza Manningham-Buller: “I'm not sure legacy is the right word because throughout its history any organization is affected by what it has to deal with. [...] We were, as I mentioned already in the middle of a big expansion as a result of 9/11. And I believe the organization is self-critical and constantly trying to get better at what it does.”

She emphasizes MI5’s ongoing commitment to adapting and improving its strategies in response to evolving threats.

• [08:25] Interviewer: “As you kind of come to the end of this section on 2005, how much do you think it changed MI5? I mean, what was the legacy of the attacks for it as an organization?”

Manningham-Buller responds by highlighting the continuous drive for enhancement within MI5, acknowledging that while no agency can achieve absolute security, the pursuit of better intelligence and preventive measures remains paramount.

Conclusion

Eliza Manningham-Buller’s candid reflections offer a nuanced understanding of the complexities faced by intelligence agencies in the post-9/11 world. From high-stakes interactions with global leaders like Vladimir Putin to grappling with the persistent shadow of Al-Qaeda-inspired terrorism, the episode provides a comprehensive look into the challenges and triumphs of MI5 under her leadership.
