UK and Japan launch £18 billion partnership for nuclear power and jobs

Today in London, Prime Ministers Keir Starmer and Sanae Takaichi signed an £18 billion investment deal focused on clean energy and advanced technology.

The agreement includes roughly £9 billion from Japanese firms to develop floating offshore wind projects in the UK and a major partnership with Rolls-Royce to build mini nuclear reactors. These small modular reactors are designed to provide consistent power for sensitive sites like data centers and military bases while supporting climate goals. Beyond energy, the two nations reinforced their commitment to a joint fighter jet project and established a fund to help startups develop "dual-use" technologies for both civilian and military use.

Both leaders are now heading to next week’s G7 summit, where they expect to finalize further details on global economic security.
