Blaise Metreweli has been appointed as the new Chief of the UK’s Secret Intelligence Service (MI6), marking a historic first as she becomes the first woman to lead the agency since its establishment over a century ago.
Metreweli, 47, is currently the agency’s head of technology — a role often likened to “Q” from the James Bond series — and will formally assume the top post in October, succeeding Sir Richard Moore, who is stepping down after a five-year term.
Prime Minister Sir Keir Starmer personally interviewed the final candidates and called Metreweli’s appointment a “historic” step, underscoring the significance of her leadership at a time of “unprecedented” security threats to the United Kingdom.
A Lifelong Spy and Tech Innovator
Metreweli, who holds a degree in anthropology from the University of Cambridge, has spent 26 years in British intelligence. Her early career was rooted in counter-proliferation, working on the technical and strategic dimensions of nuclear security. Described as a “geek” by colleagues, she has extensive operational experience across Europe and the Middle East, including in high-risk zones, and is fluent in Arabic.
Though initially applying to the diplomatic corps, Metreweli was diverted into intelligence recruitment — a move that would place her at the heart of some of the UK’s most sensitive security operations. Her surname, of Georgian origin, reflects her Eastern European heritage.
She has also served at MI5, the domestic security service, where she led directorate ‘K’, overseeing threats from hostile states such as Russia, China, and Iran — areas of growing strategic concern.
New Leadership in a Dangerous Era
Metreweli’s appointment comes at a moment of global uncertainty. Outgoing Chief Sir Richard Moore recently remarked that the world was “more dangerous than at any time” in his nearly four-decade career. He pointed to the rise of Islamist terrorism, the assertiveness of China, and the ongoing instability from Russia’s invasion of Ukraine as key challenges.
Her deep understanding of Middle Eastern affairs is expected to be critical amid ongoing tensions between Israel and Iran, as well as the broader regional shifts shaping global security.
One of Metreweli’s foremost tasks will be to manage MI6’s evolving relationship with the CIA. While historically close, the two agencies have been facing growing divergence in priorities under the current U.S. administration. The UK’s intelligence community is also working to recalibrate its technological capabilities and cyber defense posture in the face of new-generation digital threats.
Cracking the Glass Ceiling
Metreweli’s appointment shatters a longstanding gender barrier at MI6. While MI5, the UK’s domestic intelligence agency, has already had two female directors-general, MI6 had never before appointed a woman to its top job. Her rise reflects a broader, though still incomplete, shift in gender representation at senior levels of British intelligence.
Three of the four director-general roles beneath the Chief are now held by women. Yet, gender disparities remain: the agency’s own data shows a 7.9% average pay gap between men and women.
Baroness Meta Ramsay, a veteran former SIS officer, hailed the appointment as long overdue. “At last, the glass ceiling has been smashed,” she said.
Stepping Into the Public Eye
As the only publicly named member of MI6, Metreweli will now become the visible face of one of Britain’s most secretive institutions. Though her public profile has been carefully protected over the years, she was awarded a Companion of St Michael and St George (CMG) last year for her service to British foreign policy.
Metreweli had been scheduled for an overseas posting this summer, but her plans changed following the selection process, which saw three women and one man shortlisted. Her extensive expertise in intelligence technology and leadership in high-stakes global missions ultimately secured her the role.
She expressed her gratitude in a brief statement, saying she was “proud and honoured” to lead MI6, and looked forward to continuing to work alongside “the brave officers and agents of MI6 and our many international partners.”
As Metreweli prepares to take over the role known internally as “C,” Britain’s spy agency enters a new chapter — one shaped by both global threats and a long-awaited step forward in gender representation.
