Blaise Metreweli expected to say UK faces new ‘age of uncertainty’ in speech identifying Kremlin as key threat

Assassination plots, sabotage, cyber-attacks and the manipulation of information by Russia and other hostile states mean that “the frontline is everywhere”, the new head of MI6 will warn on Monday.

Blaise Metreweli, giving her first speech in the job, is expected to say the UK faces a new “age of uncertainty” where the rules of conflict are being rewritten, particularly in light of wider Kremlin aggression after the invasion of Ukraine.
