Blaise Metreweli used her first public speech as head of MI6 at the agency's London headquarters to warn that the United Kingdom is already on the frontline of an expanding Russian campaign that uses disinformation, sabotage, cyberattacks and broader destabilization operations.She described Moscow's approach as deliberate statecraft, saying Vladimir Putin is dragging out negotiations over a ceasefire in Ukraine while probing the West with tactics that stop short of full-scale war and predicted further cyberattacks and targeted killings.Speaking alongside Richard Knighton she urged whole-of-society mobilisation across universities, the National Health Service and the rail network, and European leaders, including Volodymyr Zelensky in Berlin, and EU officials have tightened measures such as sanctions after incidents, including weather balloons over Lithuanian airspace, that officials say fit a wider covert sabotage campaign.
