The joint statement by France, Germany, the United Kingdom and the United States presents the June 2026 meeting of the IAEA Board of Governors as a test of whether the Agency can still carry out safeguards in Iran. In the text published by the UK Government, the four governments thank the Director General for his latest reports and restate full support for the IAEA’s independent role in verifying Iran’s obligations under the Nuclear Non-Proliferation Treaty and relevant UN Security Council resolutions. The immediate issue, as framed in the statement, is not only the status of Iran’s nuclear programme but whether the inspection system can still function when access is withheld. The four governments treat IAEA verification as the legal and technical basis on which the wider non-proliferation system depends.
According to the statement, one year has passed since the Board found Iran in non-compliance with its NPT Safeguards Agreement. The four governments say that finding followed more than two decades of insufficient cooperation with the Agency and repeated IAEA reporting on undeclared nuclear material and activities in Iran. Their argument is that, over the past year, Iran has not remedied those concerns and has instead taken further steps that deepen the breach. That distinction matters in policy terms. The language used is not simply diplomatic criticism. It is a claim that Iran is failing to meet specific legal obligations attached to its safeguards agreement, with direct consequences for the IAEA’s ability to verify declared material and report to member states.
The sharpest concern in the statement is access. The four governments say Iran has not allowed the Agency to inspect Fordow, Natanz and Isfahan for a year, and that, since the previous Board meeting, in-field verification has been permitted only at the Bushehr power plant. They also say Iran has not implemented the special measures provided for in its safeguards agreement, including the production of reports requested by the IAEA on affected facilities and associated nuclear material. Without site access and facility reporting, the Agency cannot complete ordinary verification work. In practical terms, that means safeguards accountancy moves from delayed to incomplete, and the Board is left without the evidence base it would normally expect when assessing compliance.
The statement links those access restrictions directly to the IAEA’s safeguards conclusion for 2025. It says the Agency cannot conclude that Iran’s previously declared nuclear material has remained in peaceful use because it has been unable to verify that material, including 440 kg of high-enriched uranium. It also says the Agency cannot verify whether all enrichment-related and reprocessing activities have been suspended, particularly in the context of the newly declared facility in Isfahan. The source text adds that Iran remains the only state without nuclear weapons to have produced and accumulated uranium enriched up to 60%. The policy significance lies not only in the enrichment level but in the absence of on-the-ground verification. As presented in the statement, material of high proliferation concern has remained unaccounted for by inspectors for a full year.
The four governments also draw attention to two technical compliance issues that carry significant weight in safeguards practice. They say Iran is still not implementing modified Code 3.1, which requires earlier notification of design information for nuclear facilities, and they say Iran continues to ignore Security Council and Board resolutions calling for the immediate implementation of the Additional Protocol. The statement places those points alongside the Director General’s longer-running concern about possible undeclared nuclear material and activities in Iran. Taken together, the argument is that the current dispute is wider than access to a small number of sites. It concerns both declared material and unresolved safeguards questions that the Agency says remain open.
On safety, the statement acknowledges that Agency verification activities in Iran have been affected by conditions on the ground. It then argues, by reference to the Director General’s reporting, that Iran has shown it is able to facilitate inspections when it considers visits to be in its interests. The four governments add that the Agency has repeatedly stated there is no current technical or nuclear safety reason preventing inspectors from resuming in-field verification at all declared facilities. That framing narrows the dispute. If safety is not the present barrier, the issue becomes one of state cooperation and legal compliance rather than operational feasibility. The statement therefore presents Iranian obstruction, rather than external conditions, as the main reason the IAEA cannot fully discharge its mandate.
The statement supports a draft resolution introduced by the United States and the E3, setting out what it describes as concrete and immediate steps for Iran to return to full compliance with its safeguards obligations and relevant UN Security Council resolutions. It repeats the Director General’s position that implementation of the NPT Safeguards Agreement cannot be suspended under any circumstances and says the Board must act to uphold the authority of the IAEA. At the same time, the four governments say they remain committed to diplomacy and to a negotiated outcome that would ensure, in a verifiable and durable way, that Iran cannot acquire a nuclear weapon. The statement closes by taking note of IAEA reports GOV/2026/33 and GOV/INF/2026/9 and asking that both be made public. That leaves the immediate policy focus on two tracks running together: a stronger Board response on safeguards compliance and continued diplomatic work towards a negotiated settlement.
