Chancellor Rachel Reeves announced a £1 billion investment in commercial-scale quantum computers and a £500 million fund to support leading UK artificial intelligence (AI) companies in her annual Mais lecture on Tuesday. She emphasized that closer economic ties with the European Union (EU) and rapid AI adoption are critical for boosting the UK economy amid sluggish recent growth.
Investment in AI and Quantum Computing
Reeves framed AI as the defining technology of the era, warning against the UK falling behind other countries in developing this sector. She pledged targeted public investment to accelerate the UK’s AI capabilities and secure a leading position in the G7. The £1 billion quantum computing commitment aims to advance technology that can simultaneously process multiple potential solutions, promising to reduce problem-solving time substantially.
Call for Deeper EU Economic Relations
The chancellor highlighted the importance of “deeper” ties with the EU to stimulate regional economic recovery. She discussed strengthening cooperation with Ireland’s finance minister Simon Harris as part of this approach. The UK economy showed no growth in January and a modest 0.2% increase in the first quarter, with the Office for Budget Responsibility (OBR) recently revising 2026 GDP growth forecasts downward to 1.1% from 1.4%.
Policy Context and Political Response
Reeves advocated for a strategic state role focused on stability, investment, and reform to drive economic growth. She urged the UK to “chart our own course” on AI to avoid ceding control of technology development to markets dominated by a wealthy few or foreign powers with differing values.
In response, Conservative shadow chancellor Mel Stride criticized Reeves and Labour’s economic approach, accusing them of attempting to use Brexit as a scapegoat for economic challenges.
