Chi Onwurah, the Member of Parliament for Newcastle upon Tyne Central and chair of the Commons Science, Innovation and Technology Committee, published correspondence with Kanishka Narayan, minister at the Department for Science, Innovation and Technology (DSIT), in which she writes that his sovereignty letter "fails to set out a coherent strategy for achieving technology sovereignty" 1. Narayan pointed to the £500 million Sovereign AI Unit (SAIU), launched in April , and a proposed "advanced market commitment" for AI hardware as the government's strategy.
The SAIU's first cohort, named on 16 April, was exclusively infrastructure-layer ; no second cohort has been announced. Narayan's "advanced market commitment" is, on Computer Weekly's reading, a phrase rather than a published policy instrument. The Open Rights Group's national security report, which put the UK's annual cloud lock-in cost to US hyperscalers at £500 million , already framed the sovereignty problem as one of demand-side capture, not capital. The SAIU's £500 million sits on the supply side.
The immediate political pressure is now on DSIT to expand beyond the seven first-cohort firms. The committee chair has put the minister on record. Across the Channel, the comparable European pressure is the seven-CEO Handelsblatt op-ed urging Brussels to deregulate, and OpenAI's decision to pause Stargate UK on energy costs while it signed an 88,500 square foot lease at King's Cross. Onwurah's letter does not name those data points. The next SAIU cohort, if it lands, will determine whether the UK's sovereignty strategy includes anything above the chip and the data-centre.
