The Spin


Pro-government narrative

The U.K.-Japan deal is a genuine economic breakthrough, unlocking over £18 billion in investment across clean energy, tech and infrastructure, which will help deliver cheap, clean and reliable energy and generate thousands of jobs. Agreements such as this represent exactly the kind of long-term partnerships the government seeks to create to achieve positive, long-term results.

Government-critical narrative

A headline number north of £18bn sounds transformative, but most of this deal is MOU-heavy diplomacy with a narrow slice of bankable contracts. The issues surrounding Hinkley Point C are a hard reminder that "strategically important" and "investable now" are two very different things. Smart money would wait for evidence to arrive, rather than trust the optics.
