The Cabinet Office published its machinery of government fact sheet on 27 July, placing AI strategy, public sector AI adoption and the AI Security Institute in the Cabinet Office following the abolition of DSIT, the Department for Science, Innovation and Technology, on 20 July 1. The document stops there. It does not name the Sovereign AI Unit, the GBP 1.1bn AI Hardware Plan announced in June , the GBP 750m national supercomputer, or the Strategic Assets contracts that ran to a second procurement wave in July .
Nor does it name an accounting officer. In Whitehall that role carries a specific meaning: the senior official personally answerable to Parliament for a programme's money, who signs the accounts and appears before the Public Accounts Committee when they go wrong. No single published document currently identifies that person for the Sovereign AI programmes, so ownership has to be read across two or more sources rather than stated in one.
The department those programmes are shared with is itself mid-rename. The Department for Business and Trade carries a banner on its gov.uk page recording that it is being replaced by the Department for Business, Innovation, Science and Trade 2. One department, two names, and a reorganisation still in progress while the spending decisions continue.
