The UK government has maintained its long-standing policy against proscribing the IRGC under the Terrorism Act 2000, preferring targeted sanctions and a proposed hostile state framework over full terrorist designation, despite the EU's February 2026 listing and repeated calls from allies, parliamentary motions, and advocacy groups. With the June 30 deadline only weeks away, no legislation has advanced through the required Home Office review, parliamentary process, or ministerial sign-off, and officials have repeatedly signaled no fast-track plans. This sustained inaction under the current administration underpins traders' near-certain consensus on a "No" outcome. A last-minute diplomatic rupture or major security incident could theoretically trigger emergency measures, though such a shift remains highly improbable given the procedural timeline and entrenched position.
