Sir Keir Starmer gave an update on the Iran conflict at a Downing Street press conference this afternoon.
The Prime Minister revealed that four extra British Typhoon fighter jets are being deployed to Qatar amid the war in the Middle East and also announced that a Government-chartered flight from Oman to Britain has now taken off.
He acknowledged that people across the UK are “worried sick”, adding: “I want to reassure the British public about the action that we are taking while the region has been plunged into chaos.
“My focus is providing calm, level-headed leadership in the national interest.”
It comes as the Prime Minister has faced criticism over his response to the crisis.
Keir Starmer scrambles as he issues major Iran update
Keir Starmer has been forced to confront one of the most dangerous foreign-policy crises facing Britain in years as the conflict involving Iran, the United States and Israel continues to create pressure across the Middle East.
The former prime minister’s approach to Iran became a major political issue in 2026, particularly after Britain found itself caught between its longstanding alliance with Washington, its security commitments in the region and Starmer’s repeated insistence that Britain should not be dragged into a war that was not in the national interest.
The situation has since developed considerably.
The United States and Israel launched major strikes against Iran on February 28, while Iran responded with attacks against Israel, US military facilities and targets in several Gulf states. Britain did not participate in the offensive strikes, but British forces were deployed in a defensive capacity to protect personnel, allies and regional infrastructure.
That distinction became central to Starmer’s message.
He sought to reassure allies that Britain remained committed to regional security while simultaneously making clear that British forces would not automatically become participants in offensive military operations.
It was a difficult balancing act.
Starmer’s warning over Iran
At the height of the crisis, Starmer repeatedly argued that Britain’s involvement had to be guided by national interest and international law.
In April, he warned that the economic consequences of the conflict could continue to affect Britain long after the immediate fighting ended. He also said that he would not allow the UK to be dragged into a war that did not serve British interests, invoking the lessons of the Iraq conflict.
That position placed Starmer under pressure from different directions.
Some critics argued that Britain should provide stronger support to the United States.
Others believed the UK should distance itself even further from the conflict.
Polling conducted by YouGov illustrated the divide. Its survey found that 38% thought Starmer was handling Britain’s response well, while 43% thought he was doing badly. Those who approved often cited his efforts to keep Britain out of the war, while critics from both sides accused him of either doing too much or too little.
The political difficulty was therefore not simply about Iran.
It was about Britain’s role in the world.
Britain refused to join the offensive
The UK’s military position was carefully defined.
British aircraft were deployed to intercept missiles and projectiles and defend regional allies, but Britain did not participate in the initial US-Israeli offensive against Iran.
The House of Commons Library recorded that British aircraft operated defensively in areas including Qatar, Jordan, Iraq and Cyprus. Additional military assets were deployed across the region, including air defences and RAF aircraft.
For Starmer, the distinction between defensive and offensive action was crucial.
Britain could argue that it had a responsibility to protect its forces and allies without becoming a direct participant in a campaign aimed at destroying Iranian military and nuclear infrastructure.
But the distinction did not eliminate political controversy.
The United States wanted greater assistance, while British officials had to consider the risks to British personnel and the possibility that Iran could retaliate against UK interests.
The Trump problem
The crisis also exposed tensions between London and Washington.
US President Donald Trump publicly criticised Starmer’s reluctance to allow greater American use of British facilities during the early stages of the conflict.
According to reporting at the time, Starmer initially refused to allow American aircraft to use British bases for offensive operations. He later permitted limited use of British bases for strikes against Iranian ballistic missiles and missile-storage sites, while excluding other targets.
That decision reflected the complicated nature of Britain’s relationship with the United States.
London wanted to preserve the transatlantic alliance.
At the same time, Starmer did not want Britain to be perceived as simply following Washington into another Middle Eastern war.
The memory of Iraq remained an important part of the political debate.
For a Labour government that had repeatedly emphasised international law and diplomatic engagement, the question was whether Britain could remain a close American ally without surrendering independent control over its own military decisions.
Iran’s response changed the stakes
Iran’s retaliation made the crisis far more than a distant conflict.
British bases in the region came under attack, forcing the UK to strengthen defensive measures.
The House of Commons Library noted that Iranian attacks targeted US military bases and locations in Arab states where American forces were stationed, while UK facilities in Bahrain, Qatar and Cyprus were also attacked.
That created a difficult reality for the British government.
Even if London did not participate in offensive operations, British forces could still become involved because they were stationed in the region and because Britain had responsibilities towards allies.
The difference between “being in the war” and “being affected by the war” consequently became increasingly difficult to maintain.
The economic consequences
The Iran conflict also created serious economic concerns.
Energy markets were particularly sensitive to developments in the region, while disruption around the Strait of Hormuz posed a threat to global oil and shipping markets.
By September, the issue had become even more acute.
Iran was demanding conditions for reopening the Strait of Hormuz, one of the world’s most important energy shipping routes. Iranian officials indicated that Washington had only a limited period to respond to Tehran’s demands, with senior Iranian security figures referring to a four- or five-day deadline.
The implications extend far beyond the Middle East.
Any prolonged disruption to the Strait can affect energy prices, shipping costs, insurance and ultimately household expenses in countries such as Britain.
That is why British governments have a direct economic interest in finding a diplomatic route out of the crisis even when British troops are not directly involved in offensive combat.
A new diplomatic phase
By September, the emphasis had increasingly shifted towards diplomacy.
Foreign Secretary Ed Miliband met Iranian Foreign Minister Abbas Araghchi in New York on the margins of the United Nations General Assembly.
It was a significant encounter because relations between London and Tehran had deteriorated sharply during the crisis.
Miliband told his Iranian counterpart that Britain would not tolerate intimidation, threats or hostile activity on British soil from groups linked to Iran. He also pressed Tehran over the safety of British citizens detained in Iran.
At the same time, Britain continued to advocate freedom of navigation through the Strait of Hormuz and a diplomatic solution.
The meeting demonstrated how Britain’s Iran policy had evolved from an immediate question of military involvement into a broader diplomatic and security challenge.
Starmer’s Iran legacy
There is also an important political timeline to consider.
Starmer is no longer Britain’s prime minister. By September 2026, Andy Burnham was in Downing Street, while Miliband was serving as foreign secretary and handling the latest diplomatic contacts with Tehran.
That means headlines describing Starmer as currently “scrambling” over an Iran update need to be understood in their original political context rather than as a description of Britain’s present government.
Nevertheless, Starmer’s decisions remain relevant because they established important precedents.
His government chose not to participate in the initial offensive action against Iran.
It maintained a defensive military presence in the region.
It allowed limited American use of British bases under defined circumstances.
And it repeatedly emphasised diplomacy and the importance of avoiding a wider regional war.
Those decisions created a framework that subsequent governments have had to navigate.
Britain caught between allies and independence
The Iran crisis exposed a recurring dilemma in British foreign policy.
Britain is closely tied to the United States through defence, intelligence and military cooperation. It is also a European power with strong diplomatic and economic interests in the Middle East.
At the same time, British governments retain the ability to make independent decisions about the use of British forces.
The Starmer government’s handling of Iran demonstrated how difficult that independence can become when Britain’s closest ally adopts a dramatically different military strategy.
The government had to answer several questions simultaneously.
How much support should Britain provide to Washington?
How should British forces protect themselves?
What constitutes defensive rather than offensive action?
How can Britain maintain influence without becoming directly involved in the conflict?
And what should Britain do if diplomacy fails?
None of those questions has an easy answer.
The crisis is far from finished
The latest developments suggest that Iran remains at the centre of a wider confrontation involving the United States, Israel and several regional powers.
The Strait of Hormuz remains particularly important.
Iran’s demands for reopening the waterway, combined with American pressure and continuing regional military tensions, mean that even countries attempting to stay outside the conflict can still face significant economic and security consequences.
For Britain, the challenge is therefore no longer simply deciding whether to participate in a war.
It is protecting British citizens, maintaining freedom of navigation, defending military personnel, managing relations with Washington, communicating with Tehran and attempting to prevent a regional conflict from becoming even wider.
Starmer’s original Iran update came at a moment when Britain was under intense pressure to choose a side more clearly.
His response was to draw a line between military defence and offensive participation.
Whether that approach ultimately provided the right balance remains a matter for political debate.
But the facts of Britain’s position are clear: the UK did not join the initial offensive strikes, British forces nevertheless became involved in defensive operations, and the government remained committed to diplomacy even as the conflict threatened British security and economic interests.
The latest diplomatic efforts show that the Iran crisis has moved into another phase.
And although Starmer is no longer the man responsible for Britain’s response, the choices made during his premiership continue to shape the difficult decisions confronting the UK.
