Question to the Home Office:

To ask His Majesty's Government, in the light of the expulsion of the Iranian Ambassador from Australia, what steps they are taking to monitor and counter state-backed interference in the UK by Iran and other hostile states.

This Government takes state threats to the UK incredibly seriously, including those posed by Iran. In concert with international partners, we will use all appropriate tools at our disposal to protect the UK, and our interests, from state threats.

In March the Government announced new measures to tackle state threats from Iran. This included placing the Iranian state, including Iran's Intelligence Services, the IRGC and MOIS, on the Enhanced Tier of the Foreign Influence Registration Scheme (FIRS). FIRS is a critical disruptive tool for the UK and went live on 1 July 2025.

The National Security Act 2023 also provides crucial powers to respond to foreign interference and we will strengthen our legislative framework where necessary, including committing to create a new state threats proscription-style tool that will further help to protect the UK.
