The Fine Line Between Free Expression and National Security in Britain S. Rouzbeh ۱۴ اسفند ۱۴۰۴ An examination of foreign influence, threats against journalists and the legal framework discussed in the author’s account of Iranian state activity in Britain. The Fine Line Between Free Expression and National Security in Britain: Foreign Influence Under Scrutiny Britain regards freedom of expression as one of the foundations of its democracy, but does not define that right as absolute or without limits. Within its legal framework, speech that remains within the realm of opinion and political positions is, in principle, protected by law. But when speech crosses beyond debate into areas such as incitement to hatred, threats, organised harassment or cooperation with the intelligence bodies of hostile states, a case changes from a ‘political disagreement’ into a ‘security and criminal matter’. This is precisely the sensitive boundary receiving greater attention than ever in cases concerning the Islamic Republic’s activities on British soil. Security Warnings: When a Threat Becomes More Than a Hypothesis In recent years, the British government has officially stated that state threats no longer take only the traditional form of espionage. According to an official statement by Britain’s security minister, the boundary between online and offline activity, and between diplomatic activity and proxy operations, is blurring. Figures show a 48 per cent increase in state-threat investigations managed by MI5, indicating that Britain faces an unprecedented security challenge. In successive speeches in October 2024 and October 2025, MI5 Director General Ken McCallum issued explicit warnings about Iranian activity. He revealed that, since January 2022, the intelligence services and police had responded to more than 40 potentially lethal plots directed by Iran. A central point was the Islamic Republic’s use of ‘professional criminals’ as proxies to conduct assassination and abduction operations on British soil, concealing the Iranian state’s direct involvement. Examining the Recent Arrests: The Birmingham Case On 8 February 2026, West Midlands Police announced the arrest of a woman in connection with an event described as the ‘Anti-Zionist Movement’ in Birmingham. The initial allegation was ‘stirring up racial hatred’, but inquiries showed that London’s Metropolitan Police also wanted her in connection with a similar pattern of behaviour on social media. She is a journalist for Iran’s Press TV. This case shows that British police no longer view incidents in isolation. In British law, ‘context and networks’ matter as much as the words themselves. When a speech or social media post forms part of an organised campaign to intimidate people or advance the objectives of a foreign power, it is treated as a criminal offence and falls outside the protection of freedom of expression. A New Legal Architecture: The National Security Act and FIRS Britain has not confined its response to police action, but has moved towards changing the legal framework. The National Security Act 2023 gave the justice system new tools. One of the most important is the Foreign Influence Registration Scheme, or FIRS. According to the British government’s official guidance concerning Iran, the scheme, fully operational since July 2025, requires transparency about activities undertaken at the direction or under the control of foreign governments. Its purpose is to distinguish ‘free civic activity’ from a ‘directed mission’. In the same context, in May 2025 the Crown Prosecution Service charged three Iranian nationals with assisting a foreign intelligence service under this new legislation. The Iran International Case: A Symbol of Terrorism Against the Media One of the best-documented areas of influence and intimidation concerns London-based Persian-language media. The parliamentary Intelligence and Security Committee’s report explicitly states that the Islamic Republic sees organisations such as Iran International and BBC Persian as primary targets. The threats were serious enough to force the broadcaster to move its operations temporarily to the United States. The stabbing of Pouria Zeraati in March 2024 marked a culmination of this violence. Reuters reports confirmed that British counter-terrorism police investigated the attack because of his occupation and professional activities. The arrest of a third person in the case in January 2025 demonstrates the police’s continuing efforts to uncover the networks behind these organised assassination attempts. Quiet Threats Against the Diaspora Alongside the major cases, a layer of ‘transnational repression’ affects the everyday lives of Iranians living in Britain. According to Parliament’s Joint Committee on Human Rights, online harassment, threats to families inside Iran and discreet surveillance are used to create a ‘chilling effect’ and silence critics beyond the country’s borders. Although precise figures for all these smaller incidents of harassment are unavailable, Metropolitan Police guidance stresses that malicious or threatening online messages can be reported and investigated. The gap between ‘threats occurring’ and ‘reporting’ is one challenge the Iranian community must address with the police in order to achieve full security. International Consensus Against State Terrorism These threats extend beyond Britain. A joint statement by 14 countries in July 2025 stressed that Iran’s intelligence services were increasingly working with international criminal gangs to carry out abductions and killings in Europe and North America. This level of criminal cooperation has placed Iran among threats comparable to Russia. Summary and Conclusion Taken together, these pieces form a picture of a country confronting a major challenge in balancing individual freedoms and national security. Britain is moving from a ‘reactive’ approach to a ‘preventive’ one. Cases such as the Birmingham arrest and attacks on journalists suggest that British security agencies have concluded that overlooking ‘harmful expression’ can come at the cost of citizens’ lives and safety. For the Iranian diaspora, understanding these laws and using the available legal tools is the only way to counter influence and organised harassment. Britain has shown that where threats, criminal proxies and instructions from foreign governments are involved, the law will act more sharply than ever.
