Iranian influence operations in the United Kingdom

The Islamic Republic of Iran has conducted a range of influence operations within the United Kingdom, according to government officials, researchers, and security analysts.

Reports have attributed these activities to efforts aimed at undermining British political cohesion, promoting narratives aligned with Iranian state interests, and targeting Iranian dissidents and journalists based in the UK. Reported activities include online influence campaigns, the dissemination of fundamentalist Islamic ideology, lobbying British politicians to encourage policies perceived as conciliatory toward Iran, and involvement in plots and intimidation campaigns.

Iranian operations are primarily attributed to the Islamic Revolutionary Guards Corps. In 2025, British government adviser, Jonathan Hall told the New York Times, the United Kingdom "Faces 'Extraordinary' Threat from Russian and Iranian Plots".
