The British government gave authorization for the United States to use military bases in Britain to carry out strikes on Iranian missile sites that are attacking ships in the Strait of Hormuz on Friday.
British ministers met on Friday to discuss the war with Iran and Iran's blocking of the Strait of Hormuz, according to a Downing Street statement.
"They confirmed that the agreement for the US to use UK bases in the collective self-defense of the region includes US defensive operations to degrade the missile sites and capabilities being used to attack ships in the Strait of Hormuz," the statement said.
Iranian Foreign Minister Abbas Araghchi decried the move, claiming that the "vast majority of the British People do not want any part in the Israel-US war" in a statement released on X/Twitter on Friday.
Araghchi accused British Prime Minister Keir Starmer of putting British lives at risk in what he called a "war of choice on Iran" and stated that Iran will "exercise its right to self-defense" in response to the "aggression."
Starmer initially rejected US request
Starmer said this week Britain would not be drawn into a war over Iran. He initially rejected a US request to use British bases for the strikes on Iran, saying he needed to be satisfied that any military action was legal.
But Starmer modified his stance after Iran conducted strikes on British allies across the Middle East, saying that the United States could use RAF Fairford and Diego Garcia, a joint US-UK base in the Indian Ocean.
US President Donald Trump has repeatedly attacked Starmer since the conflict started, complaining he was not doing enough to help him.
On Monday, Trump said there were "some countries that greatly disappointed me" before he singled out Britain, which he said had once been considered "the Rolls-Royce of allies."
The Downing Street statement on Friday called for "urgent de-escalation and a swift resolution to the war."
