“We’re not going to get dragged into this war. It is not our war,” Starmer told parliament, adding that participation would not serve Britain’s national interest.Trump, speaking in a phone interview with Sky News, said he could alter an agreement limiting the impact of U.S. tariffs on Britain, signaling potential economic consequences for London’s stance.

He also criticized the UK’s level of support during U.S. military operations.Tensions have risen between the allies after Britain declined to allow its bases to be used for initial U.S. strikes on Iran last month.

London later approved a request for the use of two bases for what officials described as a “specific and limited defensive purpose.”Starmer emphasized the resilience of the bilateral relationship, referencing the planned state visit of King Charles III to the United States and stating that ties between the two countries extend beyond individual leaders.

Trump said disagreements would not affect the royal visit but reiterated criticism of Britain’s position. “When we needed them, they were not there,” he said.The dispute reflects a broader hardening in tone from Starmer’s government toward Washington.

Finance Minister Rachel Reeves criticized the U.S. decision to launch military action against Iran as lacking a clear exit strategy, while Health Minister Wes Streeting described Trump’s rhetoric as “incendiary” and “provocative.”

Reeves was scheduled to meet U.S. Treasury Secretary Scott Bessent in Washington on Wednesday on the sidelines of International Monetary Fund meetings to discuss the economic implications of the conflict.

In a readout issued by Downing Street, a spokesperson said the two leaders discussed the failed negotiations held in Pakistan over the weekend and agreed it was “vital” to maintain the ceasefire while seeking a path forward through dialogue.

Starmer, who recently returned from meetings in the Middle East, also said international partners were working to restore safe navigation through the Strait of Hormuz, a key global energy transit route, and reaffirmed Britain’s commitment to Oman’s security.

UK Health Secretary Wes Streeting described the breakdown in talks as “disappointing,” while emphasizing that continued engagement remained necessary to achieve a sustainable end to the conflict.

Speaking to Sky News, he said diplomacy often requires persistence, adding that lack of immediate success did not diminish the value of ongoing negotiations.

Streeting also criticized comments made earlier by U.S. President Donald Trump during the crisis, calling them “extraordinary,” particularly remarks he said appeared to threaten Iranian civilization.

Separately, Australian Foreign Minister Penny Wong called for the continuation of the Middle East ceasefire and a return to negotiations, stating that the outcome of the Islamabad talks was disappointing but underscoring the need for further diplomatic efforts.

The statements come after high-level U.S.-Iran talks ended without agreement, prolonging uncertainty over a conflict that has disrupted regional stability and global energy markets.
