Far-Right Terrorism UK: Why MI5 Is Warning Now

Far-right terrorism UK is a growing concern, according to MI5 chief Sir Ken McCallum, who delivered his annual address at the agency’s London headquarters. He said the most marked trend over the past year has been a rise in cases where extremist anti-immigration and anti-Muslim grievances are tipping into terrorist intent.

Why Far-Right Terrorism UK Is Drawing Warnings

McCallum noted that extreme right-wing terrorism tends to skew young and is driven by online activity. He disclosed that MI5 had recently investigated a radicalised 13-year-old, an inquiry that produced insight allowing an international partner to prevent a lethal attack. Al-Qaeda and ISIS were also described as continuing to direct and inspire attacks.

How State Threats and AI Add to the Picture

MI5 is devoting more resources to countering state threats than during the Cold War, and McCallum warned that threats from foreign adversaries have quadrupled. Russia remains “aggressor number one,” waging hybrid warfare while avoiding actions that could trigger a joint NATO response. Almost 1,000 expulsions since the invasion of Ukraine have weakened its covert footprint, pushing it to rely on criminal proxies.

Iran is also expanding its hybrid campaign, with more than 50 arrests made over Iranian-linked activities in the past year. McCallum’s greatest concern was the potential use of artificial intelligence by extremist groups to develop bioweapons, a threat he described as not yet realised but one that could change the stakes. The UK intelligence community is working closely with the AI Security Institute to address it.

What the Warning Means for Pakistan-UK Cooperation

Security challenges of this kind reinforce the value of strong partnerships between Islamabad and London. The new Pakistan-UK dialogue channel offers regular political, economic and security talks, while Ishaq Dar’s diplomatic discussions have focused on bilateral ties and regional cooperation.

Cross-party contact also helps. The parliamentary links that keep Pakistan-UK relations steady through leadership changes provide a stable foundation for shared work on counter-terrorism and intelligence cooperation. Recent events such as the Gloucestershire terrorism arrests show why that cooperation matters, and Pakistan’s own long counter-terrorism experience positions it as a credible partner. Cultural ties add warmth to the relationship, as seen in the international release of the Pakistani film Wakhri.
