Iran Sanctions

Yvette Cooper Excerpts

Monday 13th October 2025 Written Statements

[The Secretary of State for Foreign, Commonwealth and Development Affairs (Yvette Cooper)]

We have long held concerns about Iran’s nuclear programme. It is for that reason that the UK was at the forefront of diplomatic efforts culminating in the joint comprehensive plan of action in 2015.

The JCPoA was designed to provide the international community with assurances around the exclusively peaceful nature of Iran’s nuclear programme. However, since 2019 Iran has escalated its programme far beyond JCPoA limits, with no credible civilian justification. The IAEA’s latest report from June details that Iran has over 440 kg of 60% enriched uranium.

That is why on 28 August, the UK, France and Germany —the E3—triggered the snapback mechanism at the UN Security Council. This started a 30-day process before the eventual reapplication of UN sanctions.

This step came after the UK, France and Germany had offered Iran an extension to the snapback mechanism in July. The requirements we set for an extension—including the resumption of negotiations, Iran’s compliance with its IAEA obligations, and steps to address our concerns regarding the high enriched uranium stockpile—were not met by Iran. These measures were fair and achievable.

Our snapback extension offer remained on the table during the 30-day snapback process. We continued intensive diplomacy with Iran to find a solution, including during United Nations High-Level Week where I twice met Iranian Foreign Minister Araghchi. Regrettably, Iran did not take the necessary actions to address our concerns, nor to meet our asks on extension.

The UN Security Council sent a clear message that Iran must be held accountable for its nuclear escalation by voting down two resolutions that would have extended sanctions-lifting on Iran. Following the conclusion of the 30-day UN process on 28 September, six previously terminated UN Security Council resolutions were reinstated.

On 1 October, the Government updated domestic legislation to reapply the designations and measures contained in these resolutions. This will ensure that the UK meets its international obligations as a UN member state. We would stress to other UN member states the importance of complying with the reinstated UN obligations.

The key UN obligations include: an embargo on the transfer of conventional arms to and from Iran; a ban on all enrichment, reprocessing and heavy water-related activities; financial and trade restrictions targeting Iran’s nuclear and missile programmes; and asset freezes and travel bans on 121 UN designations targeting individuals and entities involved in Iran’s proliferation activities.

The Government have gone further by designating 71 individuals and entities in sectors which have links to Iran’s nuclear programme. This includes Iranian financial institutions and energy companies as well as individuals and entities involved in facilitating Iran’s nuclear programme.

The Government have also announced that they intend to bring in legislation to impose further sectoral measures on Iran. In line with our EU partners, this will target finance, energy, trade, shipping, software, and other significant industries that are contributing to Iranian nuclear escalation.

These sanctions demonstrate our commitment to the international non-proliferation architecture and to the goal of preventing Iran from obtaining a nuclear weapon. Alongside our international partners, we will continue to pursue diplomatic routes and negotiations.
