The meeting at the Permanent Joint Headquarters in northwest London is intended to advance operational planning for reopening the strategic waterway when conditions permit, following what officials described as progress at international discussions held in Paris last week.

“The task today and tomorrow is to translate diplomatic consensus into a joint plan to safeguard freedom of navigation in the Strait and support a lasting ceasefire,” Defense Minister John Healey said in a statement.

The London conference follows talks co-chaired in Paris by British Prime Minister Keir Starmer and French President Emmanuel Macron that brought together representatives from more than 40 countries to address security in the strait, a critical global shipping route.

British and French officials have emphasized that the proposed multinational force would be defensive in nature and deployed only after a durable peace agreement is reached in the region.The United States and Iran, the principal parties to the ongoing conflict, did not participate in the Paris discussions.

A two-week ceasefire between the two countries was due to expire at midnight GMT on Tuesday, but US President Donald Trump said shortly before the deadline that it would be extended to allow further negotiations.

Both Washington and Tehran have accused each other of violating the truce, while the United States has maintained a blockade of Iranian ports.Downing Street had earlier indicated that a military planning summit would take place this week without providing further details
