UK Prime Minister Keir Starmer Welcomes United States and Iran Breakthrough Agreement to Reopen Strait of Hormuz

LONDON, June 15, 2026 – United Kingdom Prime Minister Keir Starmer warmly welcomed a milestone agreement reached today between the United States and Iran, calling it a crucial step toward ending the conflict, ensuring regional stability, and reopening the Strait of Hormuz.

In an official statement , Starmer extended his congratulations to United States President Donald Trump as well as mediators from Pakistan, Qatar, and other nations who contributed to the diplomatic breakthrough. The prime minister emphasized that the immediate focus must now shift toward fully implementing the memorandum of understanding to guarantee that the vital trade route reopens and remains permanently accessible, while finalizing the detailed elements of the nuclear agreement.

The UK government stressed that restoring toll-free freedom of navigation in the Strait of Hormuz is essential to ease the severe economic impacts felt for months by families in Britain and across the globe.

Starmer reiterated that for any peace to endure, commitments regarding Iran’s nuclear program must be robust, verifiable, and fully implemented, reaffirming the United Kingdom’s long-standing position that Iran must never acquire a nuclear weapon.

To support this transition, the UK stands ready to participate in upcoming technical talks and will continue to collaborate with international partners, including potentially deploying a defensive, independent multilateral mission alongside France to offer support in areas like mine clearance.
