The United Kingdom has ruled out joining the United States in enforcing a naval blockade of Iranian ports in the Strait of Hormuz, despite growing tensions in the region.
Prime Minister Keir Starmer has made clear that British forces will not take part in any operation to block Iranian shipping routes, distancing its government from the more aggressive stance taken by Donald Trump.
According to government sources, the UK will not deploy naval ships or troops to enforce the blockade.
However, British military assets already in the region including minesweepers and anti-drone systems will continue their operations, primarily focused on safeguarding maritime security.
A spokesperson for the UK government reiterated that Britain’s priority remains the protection of global trade routes, stressing continued support for freedom of navigation and the urgent need to reopen the Strait of Hormuz.
The waterway is a critical artery for global energy supplies, with roughly one-fifth of the world’s oil and liquefied natural gas passing through it.
The U.S. move to impose a blockade followed the collapse of recent talks with Iran in Islamabad, which had aimed to secure a lasting ceasefire after weeks of conflict.
Announcing the decision, Trump said Washington would begin “blockading any and all ships” entering or leaving the strait.
U.S. Central Command later confirmed that American forces would enforce the blockade on vessels linked to Iranian ports, while allowing passage for ships traveling to non-Iranian destinations.
Despite suggestions from Washington that allied countries, including members of NATO, could support the operation, the British government has held firm on its position. Starmer has consistently called for de-escalation and has resisted direct military involvement in the conflict.
The situation in the Strait remains tense, with Iran effectively restricting access to the route since hostilities began in late February.
The disruption has already had significant economic consequences, pushing global oil prices higher and raising concerns about inflation and energy supply worldwide.
For now, the UK appears determined to balance its alliance with the United States against its broader economic and diplomatic interests, choosing to prioritise stability in global shipping over direct participation in the blockade.
