Combatting New Forms of Extremism

Status / emerging findings

• Prevent referrals up 27% year-on-year; one in five terrorism suspects are now under 18, but only 7-9% of education referrals become active cases, suggesting possible over-referral driven by post-incident hypervigilance rather than genuine radicalisation
• 34% of Prevent referrals involve mental health or neurodiversity conditions—an overrepresentation—raising risk that autistic traits or depression are misinterpreted as extremist intent
• Antisemitic posts online exploded from 500,000 annually to 1 million per day in three years; extremist influencers including Tommy Robinson have returned to X after bans; platforms have relaxed content moderation
• Radicalisation trajectories in nihilistic online spaces now occur in days or weeks (not months/years), particularly among 14-17 year-olds; generative AI has reduced production costs of extremist content to near-zero
• Ofcom has conducted only 21 investigations into 69 websites in two years under Online Safety Act powers, with none into major platforms (X, Google, YouTube, Meta), leaving systematic harms unaddressed

Why it matters

Extremism recruitment is accelerating online and affecting younger, more vulnerable populations (teenagers, neurodiverse individuals) faster than government counter-measures can respond; without structural reform, the UK risks normalising extremist narratives while misidentifying vulnerable young people as security threats rather than safeguarding cases.

Tone arc

Started procedural and definitional (July: clarifying what 'extremism' means vs terrorism). Shifted sharply critical from October onwards after tech experts presented evidence of platform negligence and AI-enabled radicalisation. January evidence from Dame Sara Khan crystallised the critique into a systemic indictment: Whitehall's departmental silos and Prevent's lack of cross-government coordination are failing to address the speed and scale of online recruitment.
