Who is Blaise Metreweli CMG?
Metreweli CMG is set to become the first ever female chief of the Secret Intelligence Service (MI6) as announced by the Prime Minister on 15 June 2025, breaking barriers for women everywhere.
She joined MI6 as a case officer in 1999 and has held a variety of roles across the Service, with much of her career focused on operational work in the Middle East and Europe.
Currently serving as director general for Technology and Innovation at MI6, she has also held director-level positions in MI5. Metreweli studied Anthropology at Pembroke College, Cambridge.
Why is it important?
Metreweli CMG will be the 18th chief in the organisation’s history and the first woman to hold the role, at a time when the United Kingdom faces increased threats from our adversaries.
Commonly referred to as ‘C’, the chief has operational responsibility for MI6, and is the only publicly named member of the organisation. They are accountable to the Foreign Secretary.
In the secret intelligence service 116 year history, Metreweli CMG will be the first woman to hold this position.
She is currently director general ‘Q’, responsible for technology and innovation in MI6, and has previously held a director-level role in MI5. She will succeed Sir Richard Moore, who leaves the service in the autumn.
