In a historic move, the UK has named Blaise Metreweli as the new head of MI6, the first woman to lead the UK’s foreign intelligence agency since its founding in 1909.
Metreweli, 47, will succeed Sir Richard Moore this autumn, becoming the 18th Chief (known internally as “C”). She’s spent over two decades in British intelligence, working across both MI6 and MI5, and currently heads MI6’s Q section, which leads innovation and technology.
Prime Minister Keir Starmer announced her appointment, calling it “historic” and highlighting the critical role MI6 plays in a time of rising global threats from cyberattacks to hostile state activity near UK waters.
So What? Insights
-
Breaking the spy glass ceiling: This is a major gender milestone in British intelligence, echoing shifts in other top roles like MI5 and GCHQ, now also led by women.
-
A career insider: Unlike her predecessor Moore (a diplomat), Metreweli has worked entirely inside the security services, suggesting a move back to operational expertise over political connections.
-
Spycraft meets tech: As head of MI6’s tech division, her appointment signals a strategic focus on innovation critical as AI, cyberwarfare, and disinformation reshape modern espionage.
-
Life imitates Bond: Fans will note the parallel to Judi Dench’s iconic “M” character in the James Bond films. But this isn’t fiction, this is MI6 in 2025.
