As Head of the Security Service, Eliza dealt with the wake of 9/11 and a growing threat from Al-Qaeda. As Chair of the Wellcome Trust, one of the world’s largest charitable funders of medical research, she oversaw an organisation that both predicted and led work tackling the Covid-19 pandemic and its long-term effects. With insights and lessons on leadership from throughout her career, Eliza explains that leaders' priorities must change in order to keep pace with the constant emergence of new, often unimagined challenges, from existential threats such as climate change and pandemics, to urgent demands to address diversity and fairness.


Eliza Manningham-Buller headed Britain’s Security Service (MI5) from 2002 to 2007, before serving as Chair of the Wellcome Trust from 2015 to 2021, one of the world’s largest charitable funders of medical research and other activity to improve human health. From counter terrorism to pandemics, Eliza has led organisations through remarkable and pressurised times.

Eliza reflects on twenty years as a leader of two very different organisations, but which share many traits and goals in managing the unpredictable and trying to keep millions safe. She outlines how leaders’ priorities must change in order to keep pace with shifting demands from all stakeholders and the constant emergence of new, often unimagined challenges. From existential threats such as climate change and pandemics to diversity and fairness, leaders have to seriously consider an ever-changing, complex landscape of priorities that influence both their organisation’s success and society’s future. 

At MI5, Eliza led the Service through significant change, expansion, and scrutiny as it dealt with the growth of Al-Qaida terrorism after 9/11, and in response to the 7/7 attacks in London. Prior to serving as Director General her various roles took her to Washington during the first Gulf war, as well as seeing her responsible, at separate times, for work on Irish terrorism, surveillance, technical collection, finance, and IT, before she became Deputy Director General in charge of intelligence operations.

During her time as Chair of the Wellcome Trust, Eliza helped lead the UK’s biggest charity, overseeing funding for scientific research into all aspects of health and wellbeing, from infection to mental health, as well as responding to Covid-19. Having foreseen the threat of a pandemic on the scale of Covid-19, the Trust also helped to establish the Coalition for Epidemic Preparedness Innovations (CEPI).

In presentations Eliza covers lessons in leadership from throughout her career, drawing on her experience in the most demanding of environments to stress the need for leaders in any walk of life to engage in frank dialogue and invite criticism: “Do not try to be something you’re not; take responsibility for your team and remember that praising people takes seconds and can make an enormous difference. And don’t forget that humour can be found even in the most awful situations.”

Eliza is a crossbench peer, President of the respected foreign policy think-tank Chatham House, was Chair of Council at Imperial College for four years, and was chosen to deliver the prestigious BBC Reith Lectures. Her analysis of the theme Securing Freedom also formed the basis of her book of the same title.

Agent Recommendation

Leadership isn't just something Eliza talks about; it's there in everything she does. She handles questions brilliantly, her tone is steady and considered, and she holds the room in a way that only someone who’s used to being listened to can. In fact the former MI5 boss is disarmingly approachable, witty and warm (and not at all scary). JLA Agent Brogan West
