UK MI6 spy chief warns of 'aggressive' Russia threat

The head of Britain's Secret Intelligence Service, known as MI6, will warn that Russia poses an "aggressive, expansionist, and revisionist" threat, in her first speech since taking office.



Blaise Metreweli took over from Richard Moore in October, becoming the first female chief of MI6 - a role publicly known by the codename "C" - in its 116-year history.



"(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, according to advance extracts of her remarks.



"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."



Britain has sanctioned several Russian business figures, political leaders, companies, ships, and entities, including the entire GRU military intelligence agency, since Russia's invasion of Ukraine in 2022.



Over the weekend, Germany hosted U.S. and Ukrainian delegations for talks on a ceasefire deal, before a summit in Berlin later on Monday that will include European leaders.



Metreweli will also highlight the need to ramp up the use of technology to tackle threats to UK security, including terrorism and information warfare.
