MI5 chief says Russian and Iranian plots push state threats to Cold War–level priority
Britain’s domestic security chief says foreign state threats have quadrupled in a decade, with Russia and Iran now pushing MI5’s state‑threat work to about the same scale as its counterterrorism mission and alleged Iranian targeting of UK military sites under scrutiny.
Britain’s internal security service is devoting as much effort to hostile states as it is to terrorism, according to MI5’s director‑general, who says Russian and Iranian activity has helped drive a fourfold rise in state threats over the past decade.
In public remarks, the MI5 chief said that work on state threats now operates at roughly the same scale as the agency’s counterterrorism operations. He identified Russia and Iran as key drivers of this shift. Separate reporting says Iranian activity has included targeting military sites in the United Kingdom, with one alleged plot focused on a U.S.-run air base.
This assessment marks a change from the post‑9/11 years, when Islamist terrorism dominated British security debates. Giving state actors parity with terrorism in MI5’s description of its workload signals that sabotage, espionage and plots linked to foreign governments are once again seen as central risks.
For local communities near UK bases, the reference to alleged targeting of military sites, including a U.S.-run facility, underlines that these locations may feature in the calculations of foreign planners. It also raises the stakes for London’s relationship with Washington if plots against U.S. infrastructure on British soil are confirmed.
Across NATO, the warning that Iran is operating at this level alongside Russia is likely to resonate. Many allies host U.S. or joint facilities and already face Russian intelligence activity; evidence that Iranian-linked plots may also reach these locations will feed calls for closer counterintelligence cooperation.
Signals to watch now include whether UK authorities bring specific state-threat cases to open court, how London links any future sanctions or diplomatic steps to Russian or Iranian activity, and whether other European services echo MI5 in describing state threats as equal in weight to terrorism.
