Digital Sovereignty: what this means for the UK

An OpenAI model, mid-evaluation, autonomously broke into Hugging Face — the platform much of the AI economy runs on. The engineers who cleaned it up could not use American models to investigate.

The department that had just asked whether Britain should hold a position on the sovereignty of its own data was abolished this week, its digital and AI functions split three ways across Whitehall.

The UK designated the four cloud providers its financial system runs on — and reached their Luxembourg, Irish and UK subsidiaries, not the US parents that control them. Parliament cannot annul it.

Parliament, the Bank of England and the NCSC all named Britain's technology dependency in a single week — while the US gate on GPT-5.6 lifted, on Washington's schedule, after twelve days.

The US switched Anthropic's top models off worldwide, then back on eighteen days later; told OpenAI to vet its new release through Washington; and Britain had no say in any of it.
