OpenAI strikes deal to put ChatGPT in UK justice system

OpenAI is deepening its bet on Britain. The company announced a new agreement with the UK Ministry of Justice (MoJ) that will put ChatGPT Enterprise directly into the hands of 2,500 civil servants, marking one of the most significant integrations of generative AI into a major government department’s daily workflow to date.

Deputy Prime Minister and Justice Secretary David Lammy framed the deal as a matter of national competitiveness, saying the partnership “places Britain firmly in the driving seat of the global tech revolution.” The agreement follows a pilot program where staff used the tool for writing support, legal compliance, data research, and document analysis. The MoJ is the first customer to take advantage of a new UK data residency option OpenAI is rolling out on October 24th, a move designed to address data sovereignty concerns by letting British organizations store their information locally rather than in US or European servers.

The news was unveiled ahead of OpenAI’s Frontiers event in London, where CEO Sam Altman pointed to a fourfold increase in UK users over the past year. The UK has become a top-five market for OpenAI’s paid subscribers and API developers. Beyond the MoJ deal, the company’s tools already power several government projects: ‘Humphrey’ acts as an internal AI assistant for Whitehall, and ‘Consult’ automates the sorting of public consultation responses—a task that previously chewed up weeks of official time and can now be finished in minutes.

There’s a clear political logic here. The UK government wants to be seen as an AI leader, and OpenAI wants a reliable, high-profile ally in Europe. The earlier memorandum of understanding between the two already spawned Stargate UK, an infrastructure partnership with NVIDIA and Nscale designed to run OpenAI models on local computing power for jurisdiction-sensitive workloads. The MoJ deal and data residency option are the next, more tangible layers of that relationship. Whether this translates into noticeably better public services—or simply faster memo-writing—remains an open question, but the scale of the deployment suggests the government isn’t waiting around for a definitive answer.
