Prime Minister Keir Starmer said Monday that the UK would not support President Donald Trump’s proposed U.S. blockade of the Strait of Hormuz, underscoring another policy difference between the two governments over Iran.
“We’re not supporting the blockade,” Starmer told BBC Radio 5 Live. He said Britain’s diplomatic, political, and military efforts were “focused from our point of view on getting the straits fully open.”
The British government said Sunday that it continued to call for freedom of navigation and the reopening of the strait after Trump announced that the U.S. would begin a naval blockade of the waterway, a key route for global energy supplies.
“Effective immediately, the United States Navy, the Finest in the World, will begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz,” Trump posted on Truth Social on Sunday. “Any Iranian who fires at us, or at peaceful vessels, will be BLOWN TO HELL.”
In an interview on Fox News, Trump said he understood that “the UK and a couple of other countries are sending minesweepers.”
The UK has discussed deploying autonomous mine-hunting drones in the strait if allies agree on a viable plan to reopen it. Starmer had previously said those systems were “in the region.” That proposal is separate from Trump’s blockade plan.
On Monday, Starmer declined to discuss “operational matters,” but acknowledged the UK’s mine-sweeping capability while outlining British efforts to reopen the strait.
