On May 11, the British government sanctioned four members of the Zaringhalam family for links to individuals whose activities contribute to instability in the United Kingdom. At least three of them are believed to reside in London.
One of the sanctioned individuals is Farhad Zaringhalam, 44, a specialist in wireless communications and financial technology who earned both his bachelor’s degree and PhD in electronics from King’s College London.
A former Nokia employee who holds British citizenship, he serves on the board of Pergas Petro Trade Group in Iran and manages a company in Singapore. An address registered under his name belongs to a company in Dubai’s Sama Tower, both of which have been sanctioned by the United States for laundering money for the IRGC.
Farhad did not respond to Iran International’s requests for comment but told the Daily Mail he would challenge the British government’s decision.
The wider Zaringhalam family has long been linked to sanctions evasion and financial networks serving the Islamic Republic.
Nasser Zaringhalam, 66, owns Berelian Exchange. Three years ago, Iran International published exclusive footage of conversations inside his exchange office in which he explicitly referred to circumventing sanctions.
In June 2025, the US Treasury Department sanctioned both Nasser and his exchange house for involvement in terrorism financing.
Documents published by WikiIran show that Nasser and his exchange office registered at least 37 shell companies in the UAE and China and maintained more than 140 bank accounts there to evade sanctions.
One document shows him asking Zagros Petrochemical Company to transfer €3 million to Fanzhian International, a shell company in China. The transaction was processed through Zhishank Bank.
The principal shareholder of Zagros Petrochemical Company is Parsian Oil and Gas Group, which belongs to Ghadir Investment Company, the holding company of the Armed Forces Social Security Organization. The CEO of Parsian Oil and Gas Group is IRGC Brigadier General Ahmad Vahidi Dastjerdi, a former deputy defense minister.
Another leaked document reviewed by Iran International indicates that Nasser Zaringhalam laundered money for Shiraz Petrochemical Company through Moderate General Trading, his UAE-based exchange house, which is also under US sanctions. The principal shareholder of Shiraz Petrochemical is likewise the Armed Forces Social Security Organization.
A separate document shows more than €890,000 transferred through a shell company into a bank account in China before the funds were moved onward to Germany.
According to available records, Nasser Zaringhalam holds citizenship from Saint Kitts and owns a house in Finchley, a district in North London with a large Iranian population.
Britain has also sanctioned Nasser’s son, Pouria Zaringhalam, 29, who holds both British and Saint Kitts citizenship. According to municipal registration records, he has lived in properties in Finchley and Canary Wharf in recent years. In Iran, he serves on the board of Mehr Shabestan Mazandaran Company. British authorities have confirmed he resides in London.
Another sanctioned family member, Mansour Zaringhalam, 63, owns Mansour Zaringhalam & Partners Company, also known as GCM Exchange. The United States sanctioned him and his exchange office last year for financing the IRGC.
One leaked document shows Mansour delivering funds belonging to Persian Gulf Petrochemical Industries Company in cash after laundering the money and transferring it back to Iran.
Persian Gulf Petrochemical Industries Company, Iran’s second-largest company by revenue, has been sanctioned for financing the IRGC Quds Force and is a major economic arm linked to the IRGC’s Khatam al-Anbiya Construction Headquarters.
In a contract reviewed by Iran International, Mansour committed himself to creating “a suitable financial structure” for transferring money and receiving foreign currency payments. Another clause stated that he would reduce transfer risks by establishing such a network “while observing security principles.”
Britain also sanctioned Fazlollah Zaringhalam, 74, brother of Nasser and Mansour. Fazlollah, who also holds British citizenship, owns Zaringhalam & Partners Exchange and resides in London, according to the British Treasury.
Eight years ago, one of Fazlollah’s sons, Farshad, who owned an exchange office in Tehran, was sentenced to ten years in prison for disrupting Iran’s foreign exchange system. Another son, Behzad, owns an exchange office in Tehran’s Saadat Abad district.
In Tehran, however, the network’s operations appear to be coordinated in part by Mitra Zaringhalam, sister of the Zaringhalam brothers. The 53-year-old owns Zarin Tehran Investment Company. Both she and her company have been sanctioned by the United States for financing terrorism.
The sanctions come amid heightened scrutiny of Iranian-linked activity in Britain following a string of incidents in North London targeting Jewish sites and media organizations opposed to the Islamic Republic.
The group Harakat Ashab al-Yamin al-Islamiya, which is close to the Iranian government, has claimed responsibility on social media for some of the attacks.
