Frontier AI Access Is a Growing National Security Question for the UK
A University of Surrey white paper published on 27 August 2026 argues that frontier AI access has become part of UK national cyber defence — and that the June 2026 US export-control order, which forced Anthropic to disable Claude Fable 5 and Mythos 5 for every customer worldwide until 1 July, proved that access can be withdrawn without warning. This breakdown covers what Professor Alan Woodward and Dr Andrew Rogoyski actually argue, the NCSC’s measurement of a £65 automated attack, AISI’s 4.7-month capability doubling time, the five recommendations the paper sets out, why open-weight models are a weaker fallback than they look, and what UK organisations should put on their own risk registers.
