Starmer Condemns Trump's Threat to Iranian Civilians
Sir Keir Starmer has described Donald Trump's warning that a "whole civilisation" would perish unless Iran ceased hostilities as "wrong". The UK prime minister addressed MPs, stating he would not have employed the same language as the US president, who issued the threat prior to a two-week ceasefire agreement.
Sir Keir also confirmed that the UK would not participate in enforcing the US military blockade of Iranian ports, which was scheduled to commence at 15:00 BST.
In a statement to the House of Commons, the prime minister emphasized that the UK would "continue to stay out of the war" and was concentrating efforts on reopening the crucial shipping route through the Strait of Hormuz.

Ceasefire Agreement and Ongoing Tensions
Following Trump's threat on Tuesday, 7 April, the US and Iran agreed to a conditional two-week ceasefire. Despite this, Israeli forces have persisted in bombing Lebanon, and Iran continues to restrict access to the Strait of Hormuz.
After peace talks between the US and Iran over the weekend failed to produce a deal, Trump announced that the US would begin blockading all vessels attempting to enter or exit the strait.
On Monday, the president posted on his Truth Social platform, warning that Iranian naval ships approaching the US blockade would be "immediately eliminated."
UK-US Relations Amid the Conflict
President Trump has publicly criticized Sir Keir, including remarks that the prime minister is "not Winston Churchill" following the UK's decision not to join US-led military action against Iran.
As tensions between the two leaders escalated over the conflict, the relationship between their deputies has gained importance within the UK government.
The unlikely friendship between Deputy Prime Minister David Lammy and US Vice President JD Vance began when Lammy was an opposition MP and Vance had just been elected to the US Senate. Last summer, Vance and his family stayed with Lammy during a holiday visit to the UK.
Despite the differences between Sir Keir and Trump, Deputy Prime Minister Lammy spent Monday at the White House, holding separate meetings with Vice President JD Vance and US Secretary of State Marco Rubio.
Afterward, Lammy posted on X, stating it was "great to catch up with my friend JD Vance today in DC following his talks in Pakistan." Above a photograph of the two men shaking hands, he added:
"It is vital that the ceasefire continues and we get shipping flowing freely again through the Straits of Hormuz. We continue to work together towards a just and lasting peace in Ukraine."
Political Reactions to Trump's Threats
Liberal Democrat leader Sir Ed Davey criticized Trump's failure to follow through on his threat against Iran but warned that "these words are a stark reminder of how reckless, immoral, and completely outside the bounds of international law this president is." He further stated that Trump's plan to blockade the Strait of Hormuz "will only escalate this crisis and jeopardise the precarious ceasefire."
In response, Sir Keir said:
"In relation to the language about destroying a civilisation... that was wrong. A threat to Iranian civilians in that way is wrong. These are civilians, let's remember, who have suffered immeasurable harm by the regime in Iran for many, many long years. And that's why they are words and phrases that I would never use on behalf of this government, which is guided by our principles and our values throughout all of this."
UK and France to Host Summit on Conflict Resolution
Meanwhile, Sir Keir announced that the UK and France would co-host a summit focused on diplomatic efforts to end the conflict and reopen the Strait of Hormuz. The summit will also address military planning to provide assurance to shipping once the situation stabilizes.
Conservative leader Kemi Badenoch welcomed the initiative but emphasized the need for action beyond dialogue. She urged the government to publish its long-delayed defence investment plan and approve drilling for oil and gas in the North Sea to reduce the UK's vulnerability to energy price fluctuations.
Strategic Importance of the Strait of Hormuz
Approximately one-fifth of global oil and liquefied natural gas shipments transit the Strait of Hormuz, which Iran has effectively closed since US-Israeli strikes commenced on 28 February. While Iran has allowed some vessels to pass selectively, the US blockade aims to prevent Tehran from profiting from tolls on ships and revenues from oil exports.
The ongoing conflict has caused a surge in oil prices, contributing to increased energy costs worldwide.
