Internal discord has fractured the British government regarding the US-led military operations against Iran and the authorization for American forces to utilize British military bases.

According to reports from The Telegraph, during a meeting held the Friday preceding the strikes, Energy Secretary Ed Miliband, Chancellor of the Exchequer Rachel Reeves, and Foreign Secretary Yvette Cooper expressed vehement opposition to the UK supporting what they characterized as an illegal, preemptive military campaign.

Prime Minister Keir Starmer initially supported his ministers, resisting pressure from Donald Trump to permit US bombers to launch strikes against Iran from Royal Air Force (RAF) bases in Gloucestershire and the Chagos Islands.

Less than 48 hours later, however, the Prime Minister pivoted. US B-2 stealth bombers are now scheduled to arrive in the coming days at Diego Garcia, a military installation on the Chagos Islands, to conduct what have been described as “limited, defensive” missions.

President Trump indicated that large-scale US strikes remain pending, contingent upon Iran’s continued aggression toward Western allies in the Gulf and the Middle East.

Furthermore, the US has reportedly destroyed an Iranian warship with a submarine near Sri Lanka. This action marks the first such naval engagement involving a submarine since the sinking of the General Belgrano by the UK during the Falklands War.

During the National Security Council meeting on Friday, Energy Secretary Miliband voiced fierce opposition to the imminent US airstrikes, focusing on the potential repercussions for the UK’s energy security.

The meeting followed more than two weeks of contentious deliberations with President Trump and his administration.

Miliband leads opposition to Iran war

These deliberations included a heated exchange between the UK’s Deputy National Security Adviser, Matt Collins, and Elbridge Colby, the US Deputy Assistant Secretary of Defense for Strategy and Force Development.

Reportedly relying on the legal counsel of Attorney General Lord Hermer, Miliband articulated what was described as a “grumpy, pacifist, legalistic, and highly political” argument against both the airstrikes and British participation.

“He [Miliband] fundamentally dislikes Trump and dislikes this Iran business,” a source remarked to The Spectator.

Miliband’s position was supported by the Chancellor and the Foreign Secretary, who advocated for Starmer to maintain a firm stance against Washington’s pressure to join the conflict.

Conversely, Defence Secretary John Healey reportedly favored granting permission for the use of British bases to protect allies from Iranian retaliation.

The Prime Minister’s initial refusal to authorize the use of Diego Garcia drew sharp criticism from President Trump.

On Monday, Trump told The Telegraph that the Prime Minister had “greatly disappointed” him; by Tuesday, he had further remarked that Starmer was “no Winston Churchill” and was “ruining the relationship.”

According to Western officials, preparations are underway at Diego Garcia and RAF Fairford in Gloucestershire for the arrival of US combat aircraft this week.

The Telegraph also reported that the Type 45 destroyer HMS Dragon, which Starmer stated on Tuesday would be deployed to defend the British base in Cyprus, will not arrive for another two weeks as it was not slated to depart Portsmouth until next week.

The vessel had been undergoing maintenance prior to the announcement of its deployment to the Eastern Mediterranean; however, the HMS Duncan remains available for immediate deployment.

Starmer: US Aircraft Operating from UK Bases

During parliamentary proceedings on Wednesday, Conservative MP Gareth Bacon questioned the Prime Minister: “The US is our most important international strategic partner. Does the Prime Minister believe that his hesitant and ambiguous response to the events in the Middle East this week has strengthened or weakened this relationship?”

Starmer defended his position, stating that the British military had been in contact with the US for several weeks and that British forces were actively engaged in operations to protect American lives.

In the House of Commons, Starmer justified his initial decision to withhold base access, asserting that there was no legal basis or “viable, well-thought-out plan” at the time.

Starmer stated:

“US aircraft are operating from UK bases. That is how the special relationship works. British jets are intercepting drones and missiles to protect American lives in the Middle East from our shared bases. That is how the special relationship works. We share intelligence daily to ensure the safety of our people. That is how the special relationship works. Obsessing over President Trump’s recent remarks is not the special relationship.”

Military assets deployed by the UK include radar systems, ground-based air defense, counter-drone capabilities, and combat aircraft.

“Since Saturday morning, a significant number of F-35s and Typhoons have been on patrol, not just in the Middle East but across the entirety of Cyprus. Further missions were conducted throughout the night. Typhoons have been specifically tasked with the defense of Qatar, while F-35s have supported other regional partners,” the Prime Minister added.

A spokesperson for the Prime Minister subsequently stated:

“The Prime Minister has been exceptionally clear that he will only take decisions that align with the UK’s national interest and ensure the safety of the British people.”

US withheld operational details from UK

According to The Guardian, the US did not share specific operational details or the precise timing of the joint US-Israeli strikes against Iran with the UK beforehand.

The US decision to exclude the UK from the official notification loop regarding the airstrikes coincided with Keir Starmer’s initial refusal to allow US access to British military bases.

Government sources indicated that while the UK usually aligns with the US on military matters, it is difficult to determine whether the lack of formal notification was unprecedented.

A source from Whitehall confirmed that the UK was aware an operation was imminent through the buildup of equipment and intelligence via “normal channels,” but was not informed of the exact timing or operational specifics.

The UK decided to evacuate its embassy in Tehran on Friday, signaling an awareness of the impending strikes, though details regarding the timing over the weekend remained undisclosed.

RAF Akrotiri houses 4,000 personnel and is home to F-35 and Eurofighter jets. Beyond RAF Akrotiri, the UK’s largest permanent overseas airbase, the country maintains three other permanent installations in the region.

These include a naval support facility in Bahrain, a joint logistical support base in Duqm, Oman, and the Donnelly Lines facility at Al-Minhad Air Base in the UAE.

British forces also possess access to Al Udeid Air Base in Qatar.

Additionally, Diego Garcia, located in the Indian Ocean, remains within striking range for long-range US bombers targeting Iran.

Regional allies frustrated: ‘You did not protect us’

Other British allies have expressed dissatisfaction with Starmer’s response to the conflict.

Kyriakos Kouros, the High Commissioner of the Republic of Cyprus to the UK, told The Times that Cyprus expected at least a robust defense from Britain, given that the UK maintains two sovereign base areas on the island.

“The French are coming; we expect the British to be there as well, because as I said, we are not just defending the Cypriots on the island,” Kouros said.

The Times further reported that Bahrain and the United Arab Emirates have expressed concerns regarding the UK’s tepid reaction to the Middle East conflict.

The UK operates a naval support facility in Bahrain with approximately 300 personnel. This facility is located near the site where Iran launched a successful missile attack against the US Fifth Fleet headquarters.

Defence Secretary John Healey noted that the missile impacted less than 200 meters from British forces.

Gulf nations, including the UAE, have been reportedly incensed by the delay in granting permission to use joint bases, including Diego Garcia, to conduct “defensive” airstrikes against Iranian missile sites.

Public criticism reflects deep-seated frustration among Britain’s regional allies regarding the perceived slow response to Iranian retaliation.

A source familiar with the concerns of the UAE remarked: “There was a sense that the Prime Minister had to be dragged there. This clearly leaves a poor impression in the eyes of the Gulf Cooperation Council.”

Royal Navy Wildcat helicopters, equipped with Martlet missiles capable of neutralizing aerial threats, are scheduled to arrive in Cyprus in the coming days.

Kouros noted that while the deployment of the HMS Dragon was “welcomed,” the vessel’s arrival remains more than a week away.
