About Baroness Eliza Manningham-Buller

Eliza Manningham-Buller draws 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 remember that humour can be found even in the most awful situations.


Eliza Manningham-Buller headed Britain’s Security Service (MI5) from 2002 to 2007, leading the organisation though substantial change in the wake of 9/11 and the growing threat from Al-Qaeda.

During her time at the helm MI5 doubled in size, opened eight new offices and altered its approach to the professional development of staff with the establishment of a training academy.  Earlier in her career, Eliza led the Service’s investigation into the Lockerbie bombing. She served in Washington during the first Gulf war, returning to establish MI5’s intelligence effort against the Provisional IRA in mainland Britain. She joined the board and assumed lead responsibility for work on Irish terrorism, surveillance, technical collection, finance and IT before becoming Deputy Director General in charge of intelligence operations.
