UK Secures £18bn Investment Deal With Japan Amid Brexit Reset Scrutiny

The UK government has secured an £18bn investment deal with Japan to bolster post-Brexit trade and security ties, according to a June 13 report by City AM. The agreement focuses on technology and life sciences, featuring a £9bn five-year investment pipeline intended to fund innovation hubs, office spaces, and new towns.

Prime Minister Keir Starmer characterized the agreements as landmark deals that would lift the UK economy and improve trade with the world’s fourth largest economy. The announcement followed a visit to Downing Street by Japanese Prime Minister Sanae Takaichi.

What does the UK-Japan investment deal include?

The deal establishes several specific corporate and research partnerships. Rolls-Royce will collaborate with Japan’s Atomic Energy Agency on nuclear research, while the Japanese life sciences firm Eisai plans to invest £48m into quantum technology and AI.

Starmer stated the investment pipeline represents a vote of confidence in the UK economy. He noted that the £9bn commitment is expected to drive the development of high-quality infrastructure and innovation centers over the next five years.

Why is the Global Combat Air Programme facing delays?

Downing Street has not yet confirmed specific details regarding the Global Combat Air Programme (GCAP) within the broader security framework. The £6bn joint project between the UK, Italy, and Japan is a central component of the Defence Investment Plan (DIP), but the plan has faced setbacks following the resignation of John Healey.

Documents shared alongside the investment deal indicate that both parties intend to confirm a shared commitment to the GCAP. According to the text, an international contract for the stealth fighter jet programme is expected to be signed by June 30, 2026.

How does the EU “reset” compare to existing trade data?

While the UK strengthens ties with Japan, researchers at Policy Exchange have questioned the economic viability of Starmer’s proposed “reset” with the European Union. The think tank suggests the new deal may cost British citizens more than the benefits estimated by government analysts.

The Policy Exchange report specifically disputes a government claim that a food standards deal would add £9bn annually to the UK economy. Researchers argued that new regulations associated with the deal would instead increase costs for UK producers.

The report also highlighted a gap in energy targets. It raised concerns over a requirement to reach 42.5% renewables in total energy consumption by 2030, noting that the UK’s current share has dipped as low as 16.4%.

Lord Lilley, the former trade secretary who managed the UK’s entry into the EU single market, stated he was wrong to previously claim that a free trade framework would boost exports. He provided the following data to support his position:

Over our 28-year membership British goods exports to the EU grew less than one per cent a year, while our exports to countries we had no trade deal with grew four times as much—by 87 per cent.

Lord Lilley

Lilley argued that the current unilateral submission to EU rules will not assist exporters who already comply with those standards. Instead, he claimed it will burden the 92% of British firms that do not export to the EU with overregulation that has hindered growth within the EU.

The UK government’s agreements on energy markets and food standards are scheduled for parliamentary scrutiny before they can take effect.
