No 10 says Falklands sovereignty rests with UK after report of US 'review'

Conservative leader Kemi Badenoch said the reported US stance on the Falkland Islands was "absolute nonsense", adding: "We need to make sure that we back the Falklands. They are British territory."

Reform UK's Nigel Farage said: "This is utterly non-negotiable. There is no way we're even going to have a debate about the sovereignty of the Falkland Islands."

He also said he would raise the issue with Argentina's President Javier Milei when he meets him later this year.

Liberal Democrat leader Sir Ed Davey has once again called for the King's upcoming visit to the US to be cancelled.

"This unreliable, damaging president cannot keep insulting our country," Sir Ed said.

The report emerged three days before King Charles and Queen Camilla are due to travel to the US and meet US President Donald Trump at the White House.

While the White House is yet to comment on the report, it could prove to be another point of friction between the US and UK at a time of diplomatic tension.

Trump has previously said he is "not happy" with the level of support offered by the UK during its war in Iran, while Sir Keir Starmer has repeatedly said Britain will not be drawn into a wider conflict.

Meanwhile, an official from Nato - responding to the suggestion in the report that the US could push for Spain's expulsion from the military alliance - said its founding treaty "does not foresee any provision for suspension of Nato membership, or expulsion".

Earlier, Spain's Prime Minister Pedro Sanchez said: "We do not work based on emails. We work with official documents and official positions taken, in this case, by the government of the United States."
