TL;DR
Britain is “dangerously dependent” on China-dominated supply chains for materials needed for AI, defence and net zero, says a Commons report published on 5 November by the business committee and its economic security sub-committee, and covered by the Guardian. MPs want a central policy and a critical minerals finance facility. AI is one of three named concerns rather than the report’s main subject. In our view, it adds a materials dependency to UK AI planning.
What the committee found
Chair Liam Byrne put it plainly: “We cannot rearm Britain, build AI or deliver net zero unless we secure the minerals these technologies depend on.” Evidence placed the bottleneck in processing, and the report cites an International Energy Agency estimate putting China first in refining 19 of 20 strategic minerals, at an average 70% share.
The projected demand is steep. Government projections in the report have UK lithium demand 45 times its 2024 level by 2030 across eight Industrial Strategy sectors, and rare earths up 16-fold. China’s ability to halt supply, as it did with rare earths in 2025, makes that a security issue as well as an economic one. The Guardian says a reprieve on export limits runs to January 2027. The report says only elements of the controls were suspended, and a Chatham House witness told MPs that licensing continues.
Members also complained about openness. “Parliament has no visibility of the capabilities the government is seeking to protect,” the committee said, and doubted ministers would pass a single one of its 10 tests.
The government’s answer
A spokesperson rejected the idea that there is no strategy, pointing to £400 million for domestic production and recycling and to targets for 2035: 10% of demand met at home, 20% through recycling, and a 60% ceiling on any mineral from one country. The committee’s preferred route is to pool demand with G7, European and Indo-Pacific partners so that other suppliers enter the market.
What it says about AI
AI gets little detail. The report links AI infrastructure to semiconductors and data centres, and names rare earths in permanent magnets as a data centre input, but it does not rank AI supply lines by exposure. Its most specific AI point concerns procurement: the government said in March that it would favour British firms for contracts in sectors including AI, yet it has set those firms no matching duty to source minerals from home or trusted partners. In our view, that leaves UK data centre and chip projects to map their own exposure.
Looking Forward
The Chancellor’s AI package has put money behind sovereign capability, and in our view materials are the part of “sovereign AI” that gets least attention. Infrastructure investors and UK buyers of AI hardware should ask their suppliers about refining exposure now, rather than wait for a policy answer. The January 2027 date the Guardian gives for the reprieve is the first deadline to watch.
