The UK government has initiated steps to classify Iran's Islamic Revolutionary Guard Corps (IRGC) as a national security threat under the National Security (State Threats) Act 2026. This legislation aims to criminalize any form of support for the IRGC, imposing severe penalties that could include life imprisonment for specific offenses.

This legislative action follows a rise in antisemitic incidents and threats against Iranian dissidents in the UK, which officials have linked to the activities of the IRGC. The Home Secretary has emphasized that these developments necessitate a stronger stance against the group.

The decision aligns with existing sanctions on Iran and reflects the broader geopolitical tensions between Iran, the UK, and the US. Notably, the European Union has already designated the IRGC as a terrorist organization earlier this year, adding further complexity to international relations.

Reza Pahlavi, the exiled Crown Prince of Iran, may face increased challenges in returning to Iran as a result of this new legislation. Current market pricing indicates a reduced likelihood of his return by the end of the year, with the odds of a successful entry now at 5.5%, down from 6% just a week ago. This suggests that the rising tensions and criminalization of the IRGC could hinder Pahlavi's prospects.

Developments in UK-Iran relations will be critical in assessing the impact on Pahlavi's potential return. Any statements from Iranian officials or opposition figures could shape market sentiment. Furthermore, ongoing actions taken by the US and EU regarding Iran will be significant in understanding the broader geopolitical implications of the UK’s recent measures.
