UK digital‑sovereignty options mapped

A new House of Commons Library briefing says the United Kingdom still has no single digital-sovereignty policy, even as Parliament debates how dependent the state is on foreign technology suppliers. (commonslibrary.parliament.uk) The briefing was published on 6 March 2026 ahead of a Westminster Hall debate on 10 March 2026, opened by Dame Chi Onwurah, the Labour chair of the Science, Innovation and Technology Committee. It says concern about reliance on United States and Chinese technology has driven calls for a national strategy. (commonslibrary.parliament.uk; hansard.parliament.uk) In the briefing, digital sovereignty is not just about where servers sit. It covers whether government can keep access to critical technology, switch suppliers, and control data, standards, and infrastructure over the life of a service. (commonslibrary.parliament.uk) The paper maps several routes ministers and officials could take, including “sovereign cloud” rules, domestic capability building, tighter procurement, and stronger requirements for interoperability. It says open source software and open standards can cut exit risk by making systems easier to replace or connect. (commonslibrary.parliament.uk; gov.uk) That lands in a government already rewriting how it buys and runs digital systems. The Procurement Act 2023 came into force on 24 February 2025, and the Government Digital Service says a new Digital Commercial Centre of Excellence is meant to coordinate how the public sector buys and builds technology. (gov.uk; roadmap-for-modern-digital-government.campaign.gov.uk) The United Kingdom already has some of the building blocks the briefing points to, but they sit in separate policies rather than one sovereignty plan. Government guidance tells departments to “be open and use open source” in the Technology Code of Practice and to use open standards so systems are easier to expand, upgrade, and connect. (gov.uk; gov.uk) Those rules matter most in long contracts for tax, welfare, health, and local services, where replacing a supplier can take years and cost millions. The Commons Library says interoperability and portability are practical ways to reduce lock-in without requiring every service to move to a fully domestic cloud. (commonslibrary.parliament.uk) Ministers have framed the issue in strategic terms rather than as a single procurement problem. The Commons Library notes that AI minister Kanishka Narayan defined sovereignty in artificial intelligence as having “strategic leverage” and assured access to critical inputs needed for economic and national security goals. (commonslibrary.parliament.uk) The government’s broader digital reform agenda also stops short of a sovereignty doctrine. Its January 2025 blueprint for modern digital government set out a six-point reform plan, and a January 2026 roadmap said departments were pushing joined-up services, artificial intelligence adoption, stronger infrastructure, and smarter funding. (gov.uk; gds.blog.gov.uk) For now, the Commons Library’s message is narrower than “build everything at home.” The paper says the United Kingdom can gain more control by buying technology in ways that preserve competition, publish code where possible, and require systems to work with whatever comes next.
