Russia’s Federal Security Service (FSB) announced on Monday, March 30, 2026, the expulsion of a British diplomat accused of conducting intelligence and subversive activities. The diplomat, identified as Albertus Gerhardus Janse van Rensburg, the Second Secretary at the British Embassy in Moscow, has been ordered to leave the Russian Federation within two weeks.
The Allegations: Informal Meetings and False Data
The FSB, the primary successor to the KGB, claims to have uncovered a pattern of “undeclared intelligence presence” operating under the guise of the British diplomatic mission.
- Economic Espionage: According to the FSB, Van Rensburg was caught attempting to obtain “sensitive information” about the Russian economy during informal meetings with local experts.
- Falsified Visa Information: Russian authorities allege the diplomat “deliberately provided false information” when applying for his entry permit, a violation of Russian law that served as the legal basis for revoking his accreditation.
- Subversive Activities: The intelligence agency stated it had identified signs of “intelligence and subversive activities” that posed a direct threat to the security of the Russian state.
The UK Response: “Complete Nonsense”
The British Foreign Commonwealth and Development Office (FCDO) swiftly rejected the claims, characterizing them as part of a wider campaign of intimidation.
- Baseless Accusations: A Foreign Office spokesperson dismissed the spying charges as “complete nonsense” and “malicious,” asserting that the diplomat was performing legitimate diplomatic duties.
- Campaign of Harassment: London accused Moscow of orchestrating an “aggressive and coordinated campaign of harassment” against British embassy staff and their families.
- Charge d’Affaires Summoned: Russia’s Foreign Ministry summoned the British temporary Charge d’Affaires, Danae Dholakia, to deliver a formal diplomatic protest regarding the incident.
Context: Escalating Tensions and the “Shadow Fleet”
The expulsion comes amid a sharp downturn in UK-Russia relations, fueled by British support for Ukraine and recent maritime enforcement actions.
- The “Shadow Fleet” Crackdown: Just days prior to the expulsion, Prime Minister Keir Starmer and Defense Secretary John Healey announced plans for British commandos to intercept and detain vessels from Russia’s “shadow fleet” in UK waters to curb oil revenues.
- Tit-for-Tat History: This incident follows a similar expulsion in January 2026, when Moscow kicked out another British Second Secretary, leading to a reciprocal expulsion of a Russian diplomat by the UK.
- FSB Warning to Citizens: In a notable move, the FSB issued a public recommendation for Russian citizens to “refrain from holding meetings with British diplomats” to avoid “negative consequences, including criminal liability.”

A Cold War Climate
The Al Jazeera and Reuters reports suggest that espionage activities between London and Moscow have reached levels not seen since the Cold War. As both nations trade accusations of cyberattacks and sabotage, the expulsion of Van Rensburg marks yet another fracture in a diplomatic relationship that has been effectively severed by the ongoing war in Ukraine and the wider regional instability in the Middle East.
