UK's MI6 chief set to warn that Russia is a threat to the West

The head of Britain’s Secret Intelligence Service, the foreign spy service known as MI6, has warned that Russia "remains an aggressive and expansionist threat", vowing sustained support for Ukraine and calling for greater use of technology to protect UK security.

In her first public speech since taking office in October, MI6 Chief Blaise Metreweli is expected to accuse Moscow of exporting instability as part of its global strategy.

Metreweli will also say President Vladimir Putin should be in “no doubt” about Britain’s continued backing of Ukraine, according to advance extracts of her remarks.

"(Vladimir) Putin should be in no doubt, our support is enduring.The pressure we apply on Ukraine's behalf will be sustained," Metreweli will say on Monday.

She will also say that pressure on Russia will continue until Putin is forced to change his approach, describing chaos as a deliberate feature of Russian foreign policy.

"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."

Metreweli will also highlight the need to ramp up the use of technology to tackle threats to UK security, including terrorism and information warfare. She is expected to say intelligence officers must be as skilled in coding as they are in traditional espionage, calling for technology to be embedded across all areas of intelligence work.

"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," she will say.

She is the first woman to lead MI6 service in its 116-year history after replacing Sir Richard Moore.

Over the weekend and last week, Germany has been hosting talks involving the U.S. and Ukrainian delegations on a potential ceasefire deal, ahead of a summit in Berlin later on Monday (15 December) with European leaders.

Since Russia’s full-scale invasion of Ukraine in 2022, the UK has imposed sanctions on Russian business figures, political leaders, companies and ships, including the GRU military intelligence agency.

Richard Knighton, head of Britain's armed forces, will also call in a separate speech on Monday for a "whole society" approach to defence in the face of growing uncertainty and threats, and highlight an increased probability of Russia invading a NATO country.
