Starmer Says No Evidence Iran Is Targeting Mainland Britain

Prime Minister Keir Starmer told reporters there is no assessment indicating mainland Britain is being targeted by Iran, following reports that Iran fired two ballistic missiles at the U.S.-U.K. base on Diego Garcia. He emphasised routine security assessments, the need to protect British interests, careful evaluation before any action on the Strait of Hormuz, and plans to consider measures to address cost of living pressures linked to the conflict.

Key Points

  • Prime Minister Keir Starmer stated there is no assessment that mainland Britain is being targeted by Iran.
  • Statement followed reports that Iran fired two ballistic missiles at the U.S.-U.K. military base on Diego Garcia in the Indian Ocean.
  • Government will prioritise protecting British interests, de-escalating tensions, carefully consider any reopening of the Strait of Hormuz, and review measures to tackle cost of living impacts related to the conflict.

British Prime Minister Keir Starmer said on Monday that government assessments do not show mainland Britain is being targeted by Iran. He made the comment as he answered questions prompted by media reports that Iran had launched two ballistic missiles at Diego Garcia, a U.S.-U.K. military base in the Indian Ocean.

"We carry out assessments all the time in order to keep us safe, and there’s no assessment that we’re being targeted in that way," Starmer told reporters.

Starmer framed his immediate priorities as protecting British interests and working to de-escalate tensions arising from the reported strikes. He stressed the importance of careful judgment before taking steps related to the Strait of Hormuz, saying any attempt to reopen the strait would demand "careful consideration and a viable plan."

In addition to security considerations, the Prime Minister said the government will examine all available options to address the cost of living impacts tied to the Iran conflict. He indicated these discussions will form part of an ongoing response to the situation.

The Prime Minister's remarks came in response to questions about whether Britain could be a target following weekend reports that Iran fired two ballistic missiles at the U.S.-U.K. military base on Diego Garcia in the Indian Ocean. Starmer reiterated that the government routinely conducts assessments to ensure national safety and that, at present, there is no intelligence assessment indicating a direct targeting of mainland Britain.

While emphasising the absence of an assessment that Britain is targeted, he nevertheless underscored the dual objectives of safeguarding national interests and seeking to reduce tensions. He also highlighted the procedural requirement for a robust plan before any consideration to alter access or operations related to the Strait of Hormuz.

Finally, Starmer said ministers will review measures aimed at mitigating cost of living pressures that have arisen in connection with the Iran conflict, noting the government will discuss every available option to respond to those economic effects.

Risks

  • Ongoing regional tension after reports of missile strikes creates uncertainty for government security planning and public reassurance - impacts defence and public policy sectors.
  • Potential changes or policy decisions regarding the Strait of Hormuz require careful planning and carry operational uncertainty - impacts maritime and government planning sectors.
  • Cost of living pressures tied to the Iran conflict may necessitate policy interventions, adding uncertainty for household finances and fiscal planning - impacts consumer affordability and public finances.
