UK declines to enforce US naval blockade on Iran
Prime Minister Sir Keir Starmer confirmed on Monday that British forces will not participate in the United States' military blockade of Iranian ports, despite continued operations in the region.
Starmer prioritizes reopening Strait of Hormuz
Speaking to BBC Radio 5 Live, Starmer emphasized his focus on restoring access to the Strait of Hormuz, a critical shipping route, to stabilize energy prices. "We're not supporting the blockade," he stated. "Our efforts-diplomatic, political, and operational-are aimed at keeping the Strait open, not closed."
US imposes blockade after failed Iran talks
President Donald Trump announced the blockade following unsuccessful negotiations in Islamabad, Pakistan, where US and Iranian officials failed to secure a lasting peace agreement. The US Central Command (Centcom) later clarified that the blockade would apply to vessels entering or leaving Iranian ports in the Arabian Gulf and Gulf of Oman, while ensuring free passage for ships bound to non-Iranian destinations.
Centcom added that commercial mariners would receive advance notice before enforcement begins.
UK maintains regional presence without direct involvement
Starmer confirmed that UK mine-sweeping and anti-drone capabilities will remain active in the region but declined to discuss operational specifics. He reiterated his stance against direct military engagement, stating, "We're not getting dragged into this war. That's not in our national interest."
"I'm not going to act unless there's a clear, lawful basis and a well-considered plan."

Global oil prices surge as Hormuz tensions escalate
Brent crude oil prices climbed above $100 per barrel after the blockade announcement, up from $71 before the conflict. Approximately 20% of global oil and liquefied natural gas shipments transit the Strait of Hormuz, which Iran has effectively closed since US-Israeli airstrikes began on February 28.
The UK government is reviewing a planned September fuel duty increase amid opposition calls to cancel it, with Starmer noting the decision depends on developments in the coming weeks.
UK and France lead multinational shipping protection efforts
Starmer and French President Emmanuel Macron will co-host a summit this week to develop a coordinated, multinational plan to safeguard international shipping once the conflict subsides. A UK government spokesperson stressed the need for a broad coalition to protect freedom of navigation, stating, "Ships crossing the Strait of Hormuz must not be subject to tolls."
Reports indicate Iran has begun demanding $2 million (£1.5 million) in transit fees from tankers passing through the strait.
Diplomatic efforts continue amid escalation risks
Chancellor Rachel Reeves will travel to Washington this week for IMF meetings to advocate for reopening the Hormuz shipping channel. Starmer warned against further escalation in the Middle East, despite the UK's non-participation in the Islamabad talks.
Trump suggested NATO offered assistance in clearing the strait, claiming it would reopen "in not too long a distance." He also stated that the UK and other nations would deploy minesweepers, though Starmer did not confirm this.
