Suspected operatives of Iran's Islamic Revolutionary Guard Corps (IRGC) continue to hold diplomatic cover inside the European Union, according to an exclusive report by Rapporteur.

The designation matters for immigration and consular practice. Under the Vienna Convention on Diplomatic Relations, accredited diplomats enjoy immunity from arrest and prosecution in host states. That protection does not depend on the sponsoring organisation's legal status in the receiving country. As a result, individuals posted to Iranian diplomatic missions in EU member states can retain their privileges even where national authorities suspect IRGC affiliation.

Who is affected

The report concerns individuals accredited to Iranian diplomatic and consular missions across the EU whom European authorities reportedly suspect of ties to the IRGC. Their diplomatic status shields them from standard immigration enforcement. Host states cannot detain, search or prosecute them in the ordinary way.

The main remedy available to a host state is declaration as persona non grata. This forces the sending state to recall the individual or waive their immunity. Expulsion of this kind removes the person from national territory but carries no criminal consequence.

The designation question

The European Parliament has repeatedly called for the IRGC to be placed on the EU terrorist list, arguing that designation would change how member states handle suspected members and affiliates. Listing would tighten sanctions, asset freezes and entry bans applied to individuals linked to the organisation.

Until the Council acts, however, terrorism listings do not automatically strip accredited diplomats of immunity. The report indicates that the current framework leaves suspected IRGC operatives with their diplomatic cover intact.

What changes in practice

For immigration authorities, the situation creates a split track. Ordinary visa applicants with suspected IRGC links can face refusal, sanctions screening or entry bans under existing EU restrictive measures. Accredited mission staff stand outside that track: their presence rests on state-to-state accreditation, and their status can only be revoked through diplomatic channels.

Member states retain national discretion. Any government may expel a diplomat at any time and without stating reasons, a step several capitals have taken against Iranian personnel in past espionage-related disputes. The report suggests that, in these cases, that step has not been taken.

Why it matters

The gap between sanctions policy and diplomatic immunity sits at the centre of the EU's debate over the IRGC. Parliament's designation demands point one way; the Vienna Convention framework points the other. Suspected operatives benefiting from diplomatic cover illustrate the limits of immigration and sanctions tools when the person in question arrives on a diplomatic passport.
