Taken together, these datasets represent one of Britain’s greatest strategic advantages, and they should remain under British control and deliver lasting benefits for the British people. We must ensure that whenever public data creates commercial value, the public receives a permanent return. The AI Opportunities Action Plan recognised government data as a strategic public asset and the National Data Library will improve access and coordination. A National Data Wealth Fund would ensure that licensing revenues are invested rather than lost as day-to-day spending. Britain cannot become entirely dependent on foreign-owned systems trained on British public data that deliver private profits to individuals based elsewhere.
