On 28 April 2026, the Department for Science, Innovation and Technology used Liz Kendall’s speech at the Royal United Services Institute to place AI much more explicitly inside the UK’s economic security and national security agenda. The immediate announcement was a UK AI hardware plan, due to be launched at London Tech Week in June 2026, aimed at securing domestic capability in chips and the semiconductor technologies that support the wider AI hardware chain.

In Kendall’s formulation, AI sovereignty does not mean building every layer of the stack at home or shutting out foreign capital. The published speech defines it instead as reducing over-dependence and increasing resilience in areas judged strategically important, while continuing to use leading technology and accept inward investment. For officials, that points to a selective industrial policy: build capacity where the UK can matter, rather than attempt full technological self-sufficiency. (gov.uk)
DSIT’s argument rests on concentration of power. The department’s press release says 70 per cent of global AI compute is now controlled by five companies, and the speech links control over chips, compute and AI systems to economic, energy and defence security. The same press release argues the UK enters this contest with a $1 trillion tech sector, strong universities and the AI Security Institute. In practical terms, the government is treating access to advanced computing and semiconductor capability as a strategic dependency, not simply a growth sector. (gov.uk)
The speech also ties the new plan to existing domestic interventions. Earlier in April 2026, Kendall launched Sovereign AI, which the speech says will invest £500 million in British AI companies and combine that finance with access to the UK’s largest AI supercomputers, accelerated visas, British Business Bank support and £400 million of Ministry of Defence procurement set aside for British innovation including AI. The speech said the programme had already made two direct investments, in Callosum and Ineffable Intelligence. The stated objective is to move Britain from being mainly a user of AI tools towards being a producer of companies, infrastructure and intellectual property. (gov.uk)
On substance, however, the material published on 28 April remains high level. The press release and full speech confirm the direction of travel, but neither sets out the hardware plan’s budget, delivery structure, eligibility rules or procurement model. They do show the government’s intended focus: chips, specialist semiconductor technologies, ARM’s position in processor design, new UK hardware firms, and ARIA’s £100 million scaling compute programme, including £50 million for a scaling inference lab. Kendall used a large-market case to justify the push, saying the AI chips market is growing by around 30 per cent a year and could reach $1 trillion in the early 2030s. (gov.uk)
The second policy pillar is international co-ordination. Kendall said the UK should work more closely with other ‘middle power’ countries on investment and on standards for AI deployment, citing existing arrangements with Germany, France, Canada and Japan, while insisting this does not weaken the UK’s relationship with the United States. She also said the UK-chaired network of AI Security Institutes will publish best practice on model evaluation in July 2026; the AI Security Institute itself says its mission is to give governments a scientific understanding of the risks posed by advanced AI.

Taken together, the speech reads as a joining-up exercise across industrial strategy, defence, research infrastructure and diplomacy. It sits alongside the wider AI programme already in train, including the UK Compute Roadmap, AI Growth Zones, expansion of the AI Research Resource and a joint DSIT-AISI-NCSC research programme on secure AI computing systems; it also rejects calls to pause AI development in favour of faster but more controlled capacity-building. For semiconductor firms, universities, data-centre developers and defence suppliers, the next practical checkpoint is June 2026, when the promised hardware plan should show whether the government’s security-led framing is matched by operational detail.
