Prime Minister Keir Starmer Calls for Diplomatic Resolution Amid Escalating Israel-Iran Tensions
London, June 2025 — Amid growing fears of regional instability in the Middle East, UK Prime Minister Sir Keir Starmer has issued a strong appeal for calm and diplomacy in response to the recent escalation between Israel and Iran. His statement comes at a time when global powers are increasingly alarmed by the possibility of the conflict expanding beyond existing flashpoints.
Speaking at a Downing Street press conference, Prime Minister Starmer urged all involved parties to prioritise dialogue over military confrontation, stating that “escalation is not the answer — diplomacy must lead the way.” He stressed the urgent need for a multilateral approach to de-escalate tensions and prevent further violence.
“The United Kingdom calls on all sides to show restraint and to commit to peaceful negotiations. The consequences of continued aggression could be catastrophic not only for the region but for the wider international community,” said the Prime Minister.
The Prime Minister’s comments follow a series of provocative developments, including retaliatory strikes, heightened military activity, and inflammatory rhetoric exchanged between Israel and Iran in recent weeks. The situation has sparked concern among Western allies, including the United States and European Union members, who fear a broader regional conflict could emerge if tensions are not contained.

Starmer made it clear that the UK will work closely with its international partners, including through the United Nations and NATO, to encourage de-escalation and facilitate diplomatic dialogue.
“We are engaging with our allies to explore all possible diplomatic avenues. This is a moment for international leadership — not political posturing,” he said.
He also reaffirmed the UK’s long-standing commitment to international law and human rights, while condemning any acts that threaten civilian populations.
The UK Foreign Office is reportedly in close contact with counterparts in Washington, Brussels, and Middle Eastern capitals. According to sources, British diplomats are also encouraging backchannel communications to prevent misunderstandings and reduce the risk of accidental escalation.
Starmer’s approach has received mixed reactions at home. Opposition leaders have largely supported his call for diplomacy, although some critics argue that the UK should take a firmer stance against human rights violations and aggressive state actions.
Liberal Democrat Foreign Affairs spokesperson Layla Moran welcomed the Prime Minister’s emphasis on peace, stating, “Now is the time for Britain to lead by example and push hard for ceasefire efforts and regional stability.”
Internationally, the United Nations Secretary-General António Guterres has also called for calm, echoing Starmer’s sentiments. In a joint statement issued by several European leaders, there was a united appeal for de-escalation and a renewed commitment to the Iran nuclear deal and broader security frameworks.
With a significant number of UK citizens currently in the region, the Foreign Office has updated its travel advisories for several Middle Eastern countries. British nationals are being urged to avoid non-essential travel and register with the local embassy for emergency updates.
In Parliament, MPs from across the political spectrum have expressed concern about the safety of British citizens abroad and the potential impact of a prolonged conflict on global oil prices, security, and migration patterns.
As the situation continues to unfold, Prime Minister Starmer’s call for diplomacy underscores the UK’s broader foreign policy goal of promoting stability, human rights, and international cooperation. While tensions between Israel and Iran remain dangerously high, efforts by the UK and its allies to steer the crisis toward a peaceful resolution could prove pivotal in the days ahead.
“In times of global uncertainty, we must stand firm in our commitment to peace. Britain will do its part to bring parties to the table and prevent further bloodshed,” Starmer concluded.
