Housing Secretary Steve Reed said there is “no assessment to substantiate” assertions made by the Israel Defense Forces (IDF) that Iran has developed long-range missiles capable of striking European capitals. He stressed there is no intelligence indicating Iran is targeting the UK—or that it currently has the capability to do so.
The comments follow reports that Iran launched two ballistic missiles toward the joint US-UK military base on Diego Garcia, part of the Chagos Islands in the Indian Ocean. According to Reed, one missile failed mid-flight while the other was intercepted before reaching its target.
The attempted strike has added urgency to an ongoing debate about Iran’s missile programme. Israeli officials, including Prime Minister Benjamin Netanyahu, have argued that Tehran is advancing toward weapons capable of reaching deep into Europe. The IDF has also warned that such systems could potentially target cities like London, Paris, and Berlin.
However, UK officials remain cautious about those claims. Reed reiterated that Britain maintains strong defensive capabilities and is prepared to protect both the homeland and its overseas assets.
Military analysts suggest that while missile range can theoretically be extended by reducing payload weight, practical limitations remain. Sidharth Kaushal of the Royal United Services Institute noted that even if Iran could extend the reach of its missiles, their accuracy at such distances would be limited and they would face heavily defended airspace en route to the UK.
Iran has consistently maintained that its missile programme is capped at a range of around 2,000km. Earlier statements from Tehran indicated this limit was self-imposed to avoid being perceived as a broader global threat.
The issue has also drawn comments from international leaders. Former US President Donald Trump previously claimed Iran was developing missiles capable of threatening Europe and potentially the United States, though such assertions remain contested.
Meanwhile, former NATO commander Richard Shirreff urged caution, saying Israel’s warnings should be taken seriously but viewed in the broader geopolitical context, including the possibility of strategic messaging aimed at widening international involvement in the conflict.
Debate Over UK Involvement Intensifies
The developments come as the UK expands its support for US operations in the region, allowing the use of bases such as Diego Garcia and RAF Fairford for strikes under a “collective self-defence” framework.
The government recently widened the scope of potential targets to include Iranian-linked threats to shipping in the Strait of Hormuz, a critical global oil route.
While ministers insist these actions are defensive, opposition parties including the Liberal Democrats and the Greens have called for a parliamentary vote, warning the UK risks deeper involvement in a widening conflict.
Reed rejected those demands, arguing there is no established precedent for parliamentary approval when acting to defend British interests and personnel under threat.
As tensions persist, the question of Iran’s true missile capabilities—and how governments respond to them—remains central to the evolving security landscape.
