In a historic first, the United Kingdom has appointed Blaise Metreweli as the next head of the MI6 Secret Intelligence Service, making her the first woman ever to lead the agency at a time the country is grappling with what Prime Minister Keir Starmer described as “threats on an unprecedented scale.”
Downing Street confirmed the appointment on Sunday, noting that Metreweli will become the 18th chief of the agency when she officially takes over from Richard Moore later this autumn.
“This is a landmark moment for our intelligence community,” Starmer said in a statement. “Blaise Metreweli’s leadership comes at a time when the United Kingdom is being tested by aggressors deploying spy ships in our waters and by cybercriminals attempting to undermine our national systems.”
MI6, formally known as the Secret Intelligence Service, operates largely in secrecy, but its chief — known by the initial “C” — is the only publicly named official in the organisation and reports directly to the Foreign Secretary.
Metreweli currently serves as Director General of MI6, a role internally referred to as “Q,” overseeing the agency’s technology and innovation strategy.
She joined the service in 1999 after studying anthropology at the University of Cambridge and has since held multiple senior intelligence roles, including at MI5, the UK’s domestic security agency.

The government described her as a seasoned operative with significant experience in the Middle East and Europe, though specific details about her postings remain classified.
Metreweli’s appointment breaks a major glass ceiling in British intelligence circles, coming more than 30 years after MI5 named its first female chief, Stella Rimington, in 1992.
GCHQ, the UK’s cyber and signals intelligence agency, followed suit in 2023 by appointing Anne Keast-Butler as its first woman director.
While the fictional world of British espionage introduced a female “M” in the James Bond films — memorably portrayed by Dame Judi Dench — this real-life move marks a groundbreaking step in the leadership of the UK’s actual foreign intelligence apparatus.
Metreweli’s appointment, though significant for gender representation, is also seen as a strategic move as the UK faces increasing pressure from hostile foreign powers, cyber threats, and complex geopolitical instability.
