Blaise Metrewali, the first woman to lead Britain’s foreign intelligence service, MI6, has issued a stark warning about Russia, accusing Moscow of pursuing aggressive, expansionist ambitions that threaten global stability.
In her first public address since assuming leadership of the 116-year-old agency, Metrewali said Russia is reshaping the nature of modern conflict and exporting instability beyond its borders. As a result, she stressed, the operational frontline for MI6 now exists everywhere.
Describing Russia under President Vladimir Putin as an “acute threat,” the UK intelligence chief said the Kremlin’s posture has become increasingly aggressive, revisionist and expansionist. She reaffirmed Britain’s unwavering backing for Ukraine, which continues to resist Russia’s military campaign.

Addressing the evolving demands of modern intelligence work, Metrewali highlighted the growing importance of advanced technical skills. She said British intelligence officers must be proficient in programming languages such as Python, not only in controlled environments but also during field operations.

— Financial Times (@FT) December 15, 2025She argued that the defining challenge of the 21st century is not simply access to powerful technologies, but the wisdom with which nations deploy and govern those resources. Alongside military and cyber threats, she identified information manipulation as a key danger confronting Britain in an increasingly interconnected geopolitical landscape.
Metrewali, known within the intelligence community by the traditional title “C,” said human judgment remains central to navigating global instability. “The exercise of human agency has shaped our world before,” she said, “and it will shape it again.”
The United Kingdom has remained one of Ukraine’s strongest supporters since the outbreak of the war. According to official figures, London has pledged £21.8 billion in assistance, including £13 billion in military aid, underscoring its long-term commitment to Kyiv.
