Trade unions have called on Andy Burnham to tackle the cost of living crisis at its source by pressuring Donald Trump to bring the conflict in the Middle East swiftly to an end.
Leaders from 10 unions, including Unison, the UK’s largest, urged the prime minister to oppose further fighting in the Gulf to help bring down energy and fuel costs.
To put pressure on Trump, unions said Burnham must begin by revoking permission for the US to use RAF bases to launch airstrikes on Iran.
The demand came after the foreign secretary, Ed Miliband, arrived in Washington this week for his first meetings with Trump administration officials since taking up the role last month.
Miliband is expected to discuss the crisis in the Middle East with his counterpart, the US secretary of state, Marco Rubio, who said this week there had been progress in discussions with Iran and Oman on getting more ships through the strait of Hormuz, but that no final agreement had been reached.
Trump has vowed to give Iran “one last chance” after heavy bombing by both sides last week prompted renewed uncertainty about the outcome of the war and prospects for oil and gas prices.
The general secretaries of 10 UK trade unions, representing more than 2.3 million workers, said in their letter to Burnham that he should do more to oppose “the US and Israel’s devastating, illegal war on Iran”, which was “deepening the cost of living crisis faced by our members and the British public”.
“Since the war started, the average British household has seen its annual energy bill rise by £221, while monthly food bills are forecast to rise by £32.80. Without an end to the war, there will be no end to this cost of living crisis,” they wrote.
The general secretaries said they were encouraged by the new government’s focus on the cost of living and the measures it was taking “to make life more affordable”.
But they said they were “deeply concerned” that it had “authorised US airstrikes to be conducted from bases on British territories as part of the escalating war against Iran”.
Among the letter’s signatories were Unison’s Andrea Egan, the National Education Union’s Daniel Kebede and the University and College Union’s Jo Grady. Others represented included the Fire Brigades Union, the actors’ union Equity and the Communications Workers Union.
The general secretaries said Burnham had been quick to give permission for airstrikes from RAF Fairford in Gloucestershire and the Indian Ocean territory of Diego Garcia, which have become “increasingly important to the US due to the impact of Iranian counterstrikes on its Middle East bases”.
“The UK has a central role to play in de-escalation: the US has relied on its bases on UK territories to conduct the war, as they are capable of launching strategic bombers and sit within range of Iran,” they wrote.
“Revoking permission for the US to use these bases would have a significant impact on the US’s ability to further escalate a war that has been a catastrophe for people in the Middle East and an economic disaster for the world.”
The unions said leading economists supported their call, saying the main beneficiaries of the war were the big oil companies, which have made huge profits from the squeeze on supply after the closure of shipping lanes in the Gulf.
Jonathan Portes, a professor of economics and public policy at King’s College London and a former chief economist at the Cabinet Office, said: “The new prime minister is rightly focused on improving living standards at home.
“But the government cannot ignore that Trump’s illegal and unnecessary war – and, more broadly, his efforts to undermine the international trading system – make that much more difficult.”
Khem Rogaly, the co-director of Transition Security Project, which coordinated the letter, said: “Allowing American strategic bombers to strike Iran from Gloucestershire could well make Britain complicit in war crimes. It also enables a war that makes life more expensive for all of us.”
A spokesperson for No 10 said the foreign secretary’s comments in the US set out the British government’s position.
Miliband said after meeting Rubio: “We did not join offensive action in this war. We’ve allowed our bases to be used for defence by our allies, our Gulf allies, and that’s absolutely the right thing to do.
“But the most important thing we need to do is not escalate the rhetoric, not escalate the conflict, but find that lasting ceasefire.
“The No 1 priority for this government is to tackle the cost of living crisis that people are facing, and my job is to work with our closest ally, the US, on getting a ceasefire – a lasting ceasefire in relation to the Iran war.
“We are not there yet, and we’ve got to do everything we can to get this ceasefire in place.”
Four leading AI models discuss this article
"Union demands to revoke US basing rights risk a transatlantic breach that could outweigh any short-term de-escalation benefit on energy prices."
The article frames UK unions pressuring PM Andy Burnham to revoke US access to RAF Fairford and Diego Garcia as a direct lever to end the Iran conflict, lower energy prices, and ease the cost-of-living crisis (£221 annual energy rise, £32.80 monthly food). It presents this as economically rational, citing Jonathan Portes. Yet it glosses over the fact that UK basing rights are a core pillar of the US-UK defence relationship; revoking them would trigger a major strategic rift with Washington, potentially raising UK borrowing costs and weakening NATO cohesion. Missing context: oil price spikes are also driven by OPEC+ decisions, global demand, and Iranian mining of the Strait of Hormuz itself, not solely US/Israeli action. Miliband’s stated policy is de-escalation via diplomacy while keeping defensive basing intact.
The strongest case against is that continued US/Israeli pressure on Iran is the only credible way to reopen the Strait of Hormuz and restore 20% of global oil transit; capitulating via base revocation would embolden Tehran, prolong the supply shock, and ultimately leave UK households facing even higher energy bills for longer.
"The unions' demand is a domestic political distraction that fails to account for the UK's total lack of strategic leverage over US military operations in the Gulf."
The unions' demand to revoke US access to RAF bases is a geopolitical non-starter that ignores the UK's strategic reliance on the 'Special Relationship' for intelligence and defense. While the inflationary impact of the Strait of Hormuz disruption is undeniable—effectively acting as a supply-side tax on energy—the UK government lacks the leverage to dictate US military strategy. Markets should view this as domestic political noise rather than a credible threat to energy policy. However, if the UK were to capitulate, it would trigger a massive risk-premium spike in Brent Crude, as the loss of staging grounds would force the US into more aggressive, less precise military postures.
The unions are correct that energy-driven inflation is the primary headwind for UK household disposable income; if the government fails to address the war's economic toll, they risk a domestic labor crisis that could paralyze the very infrastructure needed for the current economic recovery plan.
"UK base policy is a geopolitical/alliance question being misframed as an energy price lever; revoking permissions would cost UK more in US relations than it would save in energy bills."
This article conflates two separate policy questions: UK base usage (a sovereignty/alliance issue) and energy prices (a commodity market issue). The unions' causal claim—that revoking RAF Fairford/Diego Garcia permissions would materially lower UK energy bills—is economically weak. Oil/gas prices reflect global supply-demand; UK base revocation would marginally reduce US strike capacity but wouldn't shift the Iran-Strait of Hormuz risk premium significantly. Miliband's framing (bases used for 'defense,' not offense) is legally defensible under NATO doctrine. The real risk: if Trump escalates unilaterally and UK refuses participation, it damages the US-UK alliance precisely when Burnham needs it for post-Brexit trade leverage. The unions are using energy anxiety to drive geopolitical pressure, but the mechanism is indirect.
If UK base denial forces Trump to use less efficient strike platforms, it could genuinely constrain Iran escalation options and reduce regional uncertainty premium—which IS priced into Brent crude. The unions may be right that marginal de-escalation tools matter at the margin.
"Ending the Iran war is unlikely to be a silver bullet for UK consumer bills; energy affordability hinges on global gas/LNG markets and policy tools, not just geopolitics."
The piece ties cost of living to a Middle East conflict and urges UK pressure to end the war, implying a quick relief for consumer bills. However, the causal link is fragile: UK energy bills are driven by wholesale gas/LNG prices, storage, and regulatory price caps, not solely by geopolitical shenanigans. Even a ceasefire could leave energy markets volatile for months due to supply normalization, LNG arbitrage, and OPEC+ decisions. The UK’s leverage over US foreign policy is limited, and domestic policy nuances (inflation, wage growth, energy subsidies) matter more for near-term affordability. The article also frames the war as clearly illegal, a normative stance that may shape sentiment more than market fundamentals.
Against this stance: a credible, durable de-escalation could rapidly reduce geopolitical risk premia and LNG costs, delivering material near-term relief to wholesale energy prices and consumer bills; thus the neutral view may underestimate upside for energy names if de-escalation sticks.
"UK base revocation would amplify rather than dampen the oil risk premium via perceived NATO fracture."
Claude's marginal de-escalation case underestimates second-order effects: base denial signals NATO fracture to Tehran and Beijing, likely spiking the uncertainty premium in Brent far more than any temporary constraint on US platforms. Gemini's risk-premium spike warning is closer; unions' pressure risks turning a commodity shock into a structural alliance cost that keeps UK borrowing costs elevated for years.
"The market risk of UK policy instability outweighs the geopolitical consequences of the US-UK defense alliance."
Gemini and Grok are overestimating the 'special relationship' as a stabilizing force for UK gilts. The real risk is fiscal, not just geopolitical. If the UK government bows to union pressure, they risk a sovereign credit rating downgrade due to perceived policy instability and the potential for a 'risk-off' move in sterling. Markets care less about the NATO rift than they do about the UK's ability to maintain a predictable, business-friendly regulatory environment amidst rising domestic populism.
"Policy instability risk is real, but only if unions move from pressure to disruptive action; rhetorical demands alone won't move gilt spreads materially."
Gemini's fiscal risk point is sharper than the geopolitical framing. But there's a timing mismatch nobody caught: gilt yields spike on *perceived* policy instability, not actual base revocation. The unions' pressure is real domestic noise, but Burnham's already signaled he won't capitulate—so markets may price this as resolved theater, not genuine sovereign risk. The real test: does union action escalate beyond rhetoric into strike action that disrupts energy infrastructure itself?
"UK basing rights matter only if conflict broadens or logistics fail; energy prices are driven by LNG/storage/OPEC+, not NATO tensions."
Claude overstates the near-term impact of base-denial on energy bills. In reality, LNG arbitrage, storage levels, and OPEC+ output dominate the UK energy curve for months, even amid de-escalation. Domestic policy credibility and supplier hedging matter more for gilt and consumer bills than a NATO fracture, unless escalation persists. So the market should prize energy-market mechanics first and geopolitics second; UK basing rights become consequential only if conflict broadens or logistics fail.
The panel consensus is that the unions' demand to revoke US access to RAF bases is unlikely to materially impact energy prices or UK borrowing costs, but it could strain the US-UK alliance and potentially trigger a sovereign credit rating downgrade if the UK government bows to pressure.
