US ices out the UK: Trump pulls the brakes on £31bn UK tech deal

The United States has slammed the brakes on the much anticipated £31bn technology investment deal. The move lays bare mounting tensions in transatlantic trade relations, which threatens to stall major advancements in UK digital infrastructure.

As policymakers in London and Washington dig in on key areas of disagreement, the future of this flagship tech collaboration now hangs in the balance, raising urgent questions about the UK’s ability to attract global tech investment.

The so-called “tech prosperity deal”, announced during Donald Trump’s state visit to the UK earlier this year, was framed by Prime Minister Keir Starmer as a “generational step change” in the transatlantic relationship. The agreement centred on major commitments by US technology companies to expand investment in British digital infrastructure, cloud computing, artificial intelligence and advanced research.

Among the headline pledges were a £22bn investment by Microsoft and £5bn from Google, alongside a range of smaller commitments across data centres, AI development and skills. The deal also included plans for a dedicated AI “growth zone” in north-east England, which the government said could unlock up to £30bn in private investment and create 5,000 jobs.

However, Washington has iced the deal, citing frustration with a lack of progress in wider trade negotiations. The pause was first reported by the New York Times, which said the Trump administration was unhappy with the UK’s continued application of a digital services tax on US technology companies, as well as its stance on food safety and regulatory issues.

Trade tensions spill into tech

While the agreement was widely billed as a technology partnership, its text made clear that implementation was conditional on “substantive progress” in broader trade talks. US officials argue that progress has stalled, particularly on issues they see as disadvantaging American firms.

Chief among these is the UK’s digital services tax (DST), a 2% levy on the revenues of large technology companies including Amazon, Google and Apple. Introduced in 2020, the tax raises around £800m a year and has long been a source of irritation for Washington.

Trump has repeatedly threatened retaliation against countries that impose digital taxes on US companies, describing them as unfair and discriminatory.

For the UK’s digital infrastructure and technology sectors, the pause introduces a layer of uncertainty at a critical moment. Hyperscale cloud investment, AI compute capacity and data centre expansion are all central to the government’s ambitions to position the UK as a global leader in advanced digital technologies.

Microsoft and Google have already committed billions to UK operations in recent years, including new data centres, cloud regions and AI research hubs. While the pause does not mean existing projects will be halted, it raises questions about the timing and scale of future expansion tied to the deal.

The proposed AI growth zone in north-east England is also now in limbo which was touted as a flagship regional development project intended to attract hyperscalers.

Is it a toxic relationship?

Politically, the pause is an embarrassment for the UK government, which had presented the deal as evidence of a renewed and modernised “special relationship” with Washington.

At the time of the deal’s announcement, both leaders spoke in sweeping terms about joint leadership in AI, quantum computing and next-generation technologies. Trump said the agreement would help the US and UK “dominate” the AI sector and lead the next technological revolution “side by side”.

The reality now appears more transactional. The Trump administration has shown repeatedly that it is willing to use investment, tariffs and market access as leverage in negotiations, even with close allies.

What happens next?

UK business and trade secretary Peter Kyle travelled to Washington last week for high-level discussions with US commerce secretary Howard Lutnick, trade representative Jamieson Greer and treasury secretary Scott Bessent. While the outcome of these crucial negotiations remains undisclosed, Kyle commented in advance of the trip, “This visit is about turning ambition into action – progressing our trade deal and securing the investment that will power growth.”

British officials have sought to play down the significance of the pause, describing it as a negotiating tactic rather than a fundamental breakdown. However, industry analysts point out that large-scale digital infrastructure investments are often resilient to political noise, and the optics of a high-profile pause could influence boardroom decisions.
