National Crime Agency
UK's lead agency for serious and organised crime; arrested a man after the Royal Marines' Smyrtos boarding.
A routine banking report drew the agency into Reform UK's finances in July 2026, and when that same material later leaked, the agency made a voluntary referral over its own conduct, one the IOPC sent back for local investigation by its Professional Standards Unit.

Russia-Ukraine War 2026: Marines board shadow tanker in ChannelBackground
The National Crime Agency (NCA) is the United Kingdom's lead law-enforcement body for serious and organised crime. Established in 2013 under the Crime and Courts Act, it operates across jurisdiction boundaries and can deploy abroad. The NCA has primary responsibility in the UK for countering money laundering, people trafficking, drug importation and, increasingly, sanctions evasion and cybercrime. Its financial-intelligence division has played a central role in enforcing Russian sanctions since 2022, working alongside OFSI (the Office of Financial Sanctions Implementation) and His Majesty's Revenue and Customs, while its National Cyber Crime Unit leads prosecutions against organised cybercrime groups.
In the context of Russia's war on Ukraine, the NCA has been involved in asset freezing operations against designated Russian individuals and has investigated several cases of suspected sanctions breaches involving UK-registered companies and individuals. The Smyrtos operation on 14 June 2026 marked the NCA's first arrest arising directly from a Royal Marines boarding operation. Following the interdiction of the shadow tanker in the English Channel, the NCA arrested an Indian national on board on suspicion of sanctions offences, a case that would test the legal framework for prosecuting non-British nationals found on non-British-flagged vessels in international waters. The case is being watched closely by sanctions-enforcement practitioners across NATO member states as a potential precedent for aggressive physical enforcement of oil price-cap measures, moving beyond financial and insurance levers.
The agency's National Cyber Crime Unit closed out its Scattered Spider case on 16 July 2026, calling the sentencing Britain's largest-ever cybercrime prosecution, the product of what Deputy Director Paul Foster described as nearly two years of joint work with the CPS and policing partners.
It ends up investigating itself
Receiving suspicious activity reports from banks is routine business for the agency: when a payment tied to Reform donor Fiona Cottrell crossed an internal compliance threshold on 10 July 2026, it reached the agency exactly the way anti-money-laundering law intends, opening an assessment rather than any public accusation.
A fortnight later the agency turned that same machinery on itself. After the underlying Reform banking data leaked, it made a voluntary referral to the IOPC on 24 July over how the leak happened; the watchdog declined to open its own inquiry and sent the complaints back for local handling inside the agency's Professional Standards Unit.
