Keir Starmer says the UK will “play full part” in efforts to reopen the Strait of Hormuz. Speaking at the G7 summit, he also congratulates US President Donald Trump, describing a move as an “important breakthrough.” The remarks come in the context of reported progress related to Iran, with multiple outlets linking the reopening effort to a deal involving Iran. The Independent and Evening Standard both report that Starmer’s comments reflect UK support for the initiative and acknowledge the US role as part of wider G7 discussions. Starmer’s statements are framed as alignment with coalition actions at the summit, where Trump is also attending. The reports do not provide further operational details on what the UK specifically would do, nor do they outline timelines or mechanisms for reopening the waterway. Overall, the sources present the same core message: Starmer backs the reopening plan and publicly credits Trump’s “breakthrough” at the G7 meeting.
