“I warmly welcome today’s agreement reached between the United States and Iran. This is a hugely important step forward in ending the war, ensuring regional stability and re-opening the Strait of Hormuz. I congratulate President Trump and the mediators from Pakistan, Qatar and elsewhere who have contributed to this breakthrough. We have long urged de-escalation and this is the progress we had hoped to see.

“Attention must now turn to fully implementing the memorandum of understanding to ensure the Strait reopens and remains fully and permanently open, and that the detailed elements of the nuclear agreement are finalised. We stand ready to support the technical talks that will now begin. Our priority is that this becomes a durable and lasting peace, and we will work with international partners to support that.

“We are clear that toll-free freedom of navigation must now be restored in the Strait of Hormuz, to begin easing the severe economic impacts that have been felt for several months – on families here in the UK and around the world.

“We will continue to work with partners to support this – including, if required, through standing up the defensive, independent multilateral mission which the UK and France have taken a leading role in planning up to this point, particularly to offer support on mine clearance in an agreed way.

“For any peace to endure, it is essential that the commitments made, particularly in relation to Iran’s nuclear programme, are robust, verifiable and fully implemented. It remains the UK’s firm and longstanding position that Iran must never have a nuclear weapon.”
