US President Donald Trump has hinted at revoking the terms of a tariff deal with the UK, citing disagreements over Britain's domestic policies and Prime Minister Keir Starmer's leadership.
The remarks come as the US and UK leaders are locked in a heated exchange over the UK's reluctance to get involved in the US's war in Iran.
Trump and Starmer agreed to a trade pact last year, which included lower tariffs on key British exports and increased quotas for certain American agricultural products.
However, Trump's ability to impose new tariffs was limited by a Supreme Court decision in February, which invalidated many of his import-duty plans.
Trump criticized Starmer's policies, including limiting oil drilling in the North Sea, and said the UK's "bad immigration policies and bad energy policies" would prevent it from succeeding.
The UK leader has rebuffed the US president's requests to assist in a blockade of the Strait of Hormuz and to allow US bombers to use British bases in the initial attack on Iran.
Despite the tensions, King Charles III is set to visit Washington at the end of the month, marking the 250th anniversary of the US's independence from Britain.
