Fact Check: Did Keir Starmer and Trump plan a 30-nation force to reopen Strait of Hormuz?

WASHINGTON, DC: Amid heightened tensions due to the US-Iran conflict and Israel-related developments, a viral post has claimed a major international conversation involving US President Donald Trump and UK Prime Minister Keir Starmer. 

The post claims that Starmer discussed military support and logistics with Trump to reopen the Strait of Hormuz and that the UK is working with more than 30 countries to ensure safe commercial shipping following the ceasefire. As the claim spreads online, it raises questions about its accuracy. Here’s a fact check of the viral post.

Claim: Keir Starmer and Donald Trump are forming a 30-nation coalition to reopen the Strait of Hormuz

On April 11, 2026, the X (formerly Twitter) account @AK Mandhan posted, "BREAKING: UK PM Starmer confirms he is coordinating with Trump to build a 'massive' 30 nation military coalition to force open the Strait of Hormuz." It has since gained over 4.3 million views. 

In a follow-up post, the same account shared additional details attributed to Starmer’s remarks. It claimed that the UK prime minister made these comments during a visit to Gulf states, including Qatar and Doha, following a fragile ceasefire between the US and Iran. 

The post further alleged, "He explicitly referenced pulling together the coalition and discussing these points with Trump the previous night (April 9). The emphasis is on ensuring safe passage for commercial shipping, which has been severely disrupted (traffic down to ~5-10% of normal levels, with only a handful of ships passing daily instead of ~140)."

The thread concluded by citing Reuters as a source for its context.

Fact Check: Claim about Keir Starmer and Donald Trump's plan has been debunked

The claim that Keir Starmer and Donald Trump are forming a “30-nation military coalition” to reopen the Strait of Hormuz is misleading and not supported by official statements.

Although Starmer and Trump have discussed the situation in the Strait of Hormuz, verified reports show that their conversations focused on diplomatic coordination, logistics, and maritime security, rather than creating a military coalition involving 30 countries.

Starmer has consistently highlighted the importance of international cooperation and freedom of navigation, with discussions often involving multiple countries. However, these efforts are mainly diplomatic and strategic in nature, not confirmed military commitments.

While countries are coordinating on issues related to the Strait of Hormuz, there is no verified evidence that Starmer and Trump are forming a 30-nation military coalition.
