Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, with reference to the Written Ministerial Statement entitled Iran Sanctions, published on 8 September 2026, what assessment has been made of the likely effectiveness of the new sanctions in constraining Iran's nuclear programme.

I refer the hon. Member to the Written Ministerial Statement on 8 September, which explains that the financial measures in the Statutory Instrument will further reduce the Government of Iran's ability to access the UK financial system and raise funds in support of its nuclear programme. The legislation also expands our powers to sanction ships - strengthening our ability to target ships enabling and facilitating Iran's nuclear programme and malign and destabilising behaviour.

As part of the UK's responsible approach to the use of sanctions, the Government continues to work closely with international partners to ensure our sanctions are effective and to minimise opportunities for sanctions evasion, or unintended consequences.
