Starmer signals major UK pivot towards EU as Trump's taunts strain transatlantic ties

Keir Starmer has announced the most significant shift in Britain’s foreign policy posture since Brexit, declaring that closer economic and defence ties with the European Union are now central to the UK’s long-term national interest – as a sustained and increasingly personal breakdown in relations with Donald Trump over the Iran war reshapes the geopolitical landscape Britain navigates.

Speaking at a press conference in Downing Street on Wednesday, the Prime Minister went further than he has at any point in his premiership in signalling ambition for a closer relationship with Brussels. He described Brexit as having caused “deep damage” and set out plans for a summer summit with EU leaders – promising it would go beyond existing commitments and pursue genuinely new ground in economic and security cooperation.

“It is increasingly clear that as the world continues down this volatile path, our long-term national interest requires closer partnership with our allies in Europe and with the EU,” he said. “It is a partnership that recognises our shared values, our shared interests and our shared future – a partnership for this dangerous world that we must navigate together.”

The Trump context

The backdrop to Wednesday’s announcement cannot be separated from the weeks of very public hostility directed at the UK from the White House. Trump has repeatedly attacked Starmer personally over Britain’s refusal to fully commit to the US-Israel military campaign against Iran, and the criticism has grown increasingly personal and contemptuous.

Trump has called Starmer “no Winston Churchill,” described Britain’s aircraft carriers as “toys,” and on Tuesday told the UK it should show “belated courage” and go and get its own oil from the Gulf. He has also repeatedly suggested that the United States could pull out of NATO – describing the alliance as a “paper tiger” and saying he “was never swayed” by it – after European allies declined to back his military operations in the Strait of Hormuz.

The context of the UK’s position is worth understanding clearly. Starmer initially refused a US request to use British military bases for offensive strikes on Iran at the start of the conflict on 28 February. He subsequently agreed to allow what he describes as “defensive missions” from certain bases, framing this as a way of limiting British involvement rather than expanding it. Trump regards that sequencing as an act of betrayal; Starmer regards it as statesmanship. That divergence in how both leaders characterise the same sequence of events has curdled into one of the most strained periods in the UK-US relationship in recent memory.

On Wednesday, Starmer dismissed the attacks as “noise” and framed his European pivot explicitly as an act of strategic independence rather than a reaction to pressure. “Whatever the pressure on me and others, whatever the noise, I’m going to act in the British national interest in all decisions that I make,” he said. He maintained that the UK remains “fully committed to NATO” and insisted he was not choosing Europe over America, but his language about the EU was notably warmer than anything he has previously offered.

What Starmer is actually proposing

The centrepiece of Wednesday’s announcement was the commitment to raise the ambition of the EU-UK summit planned for late June or early July. Previous summits have focused on ratifying already-agreed frameworks – provisional deals on closer agriculture and energy trade, and a youth mobility scheme – but Starmer made clear this time the bar is set higher.

“At that summit the UK will not just ratify existing commitments made at last year’s summit,” he said. “We want to be more ambitious and build closer economic co-operation and closer security co-operation.”

He pointed to Brexit as having caused structural damage that now needs addressing in the context of a world that has changed dramatically. The Iran war, the ongoing conflict in Ukraine, and the uncertainty around American commitment to European security have all created conditions, Starmer argued, in which the logic of deeper UK-EU partnership is simply stronger than it was even two years ago.

At the same time, he drew clear lines about what that partnership would not include. He ruled out rejoining the EU’s single market or a new customs union – constraints that significantly limit the scope of any potential deal and that will frustrate those in Brussels who view incremental UK access-seeking as cherry-picking without corresponding obligations.

We will be defined by our ability to stand up for British interests in this volatile world.

To make our country more secure and resilient.

To give working people a fairer deal and deliver more opportunities for their children.

The immediate diplomatic action

Alongside the longer-term EU announcement, Starmer used the press conference to set out concrete near-term measures on the Strait of Hormuz crisis.

Foreign Secretary Yvette Cooper will host a meeting of international partners on Thursday to assess diplomatic and political measures to reopen the Strait, with France, Germany, the Netherlands, Italy, Japan, Australia, South Korea, Canada and the United Arab Emirates among the attending nations. A total of 35 countries have signed a statement committing to work together to restore maritime security in the region.

Starmer said military planners were working on security plans for the period after any de-escalation in the conflict, with an expected first phase focused on mine-hunting and a second phase to protect oil tankers attempting to cross the area. He acknowledged that reopening the Strait was not a straightforward task: “It is not a simple task,” he said, but described it as “the single most important thing” his government was focused on achieving.

The government also announced £53 million in support for vulnerable heating oil customers – households that rely on heating oil rather than mains gas and who are particularly exposed to the wholesale market disruptions caused by the Strait of Hormuz closure.

The obstacles to a genuine reset

While the political impetus behind Starmer’s European pivot is real and the direction of travel is clear, the practical obstacles to building a substantially closer UK-EU relationship remain considerable.

Starmer’s insistence on ruling out both the single market and customs union removes what Brussels regards as the most meaningful forms of economic integration available. EU officials have consistently viewed UK requests for partial access to specific single market sectors as incompatible with the principles of the bloc – what Starmer’s critics in Brussels describe as wanting the benefits of membership without the obligations.

Britain’s attempt to join the new EU defence initiative known as Safe foundered last year over the high entry fee demanded by Brussels. And any deal that might be agreed with Starmer could, in European capitals’ calculations, be undone if Nigel Farage’s Reform UK wins the next election – which must be held by the summer of 2029. That uncertainty about Britain’s political trajectory makes Brussels cautious about investing heavily in agreements that may not survive the next parliament.

Mujtaba Rahman of the Eurasia Group consultancy put the European position plainly: “The EU sees the signals the UK government is sending but is unclear and ultimately cautious about what it means. If Starmer’s proposition is ‘we want a bit more of the single market because of greater geopolitical uncertainty’, that is unlikely to move officials in Brussels or national capitals.”

The domestic response

At home, the reaction split along predictable lines. The Conservative Party accused Starmer of attempting to “reopen the old wounds of the Brexit years,” framing the European pivot as an ideological project dressed up in the language of pragmatism.

Reform UK took a different tack, saying the press conference should have been focused on measures to reduce energy prices for hard-pressed households rather than on foreign policy positioning. Given that petrol prices have risen 13% since late February and energy bills are expected to climb further in July, it is a line of attack that will find a receptive audience.

But for Starmer, the calculation appears to be that the events of the past five weeks have shifted the terms of the foreign policy debate in Britain’s favour on the EU question – and that the summer summit represents an opportunity to embed a new direction before domestic politics, led by Reform’s local election surge, makes the window harder to exploit.

Whether the EU’s cautious approach to a Labour government they expect may be replaced within three years will allow Starmer to deliver the “ambition” he has promised at the summit remains to be seen.
