Spies must be fluent in code, says MI6 boss

In her first speech as head of Britain’s Security Intelligence Service, MI6, Blaise Metreweli is to push for the need to invest in technology to tackle threats to UK security.

In pre-released remarks, the agency’s first-ever female head is set to say: “Mastery of technology must infuse everything we do. Not just in our labs, but in the field, in our tradecraft, and even more importantly, in the mindset of every officer.”

“We must be as comfortable with lines of code as we are with human sources, as fluent in Python as we are in multiple languages.”

The new M16 chief is also set to warn of hostile state actors, Russia in particular, who are trying to destabilize the UK from abroad using cyberattacks, spreading false information, and employing criminals remotely.

“The export of chaos is a feature, not a bug, in the Russian approach to international engagement, and we should be ready for this to continue until Putin is forced to change his calculus,” she will add.

Metreweli was appointed head of M16 – a role publicly known by the codename “C” – in June this year, becoming the first female head in the spy agency’s 116-year history.

She was previously head of the tech side of espionage – known as “Q” and depicted in the Bond movies as providing agents with exploding pens and Aston Martin cars equipped with ejector seats, machine guns, and rotating plates.
