The Foreign Office summoned Russia’s ambassador, saying espionage conducted under diplomatic cover would not be tolerated. The move followed the arrest of a German-Ukrainian businesswoman, identified by prosecutors only as Ilona W., who is suspected of acting as an agent for Russia. Investigators allege that she had been in contact with a Russian intelligence officer based at Moscow’s embassy in Berlin since at least November 2023 and had passed on sensitive information, including details related to defense facilities and the movement of drones, obtained through contacts within Germany’s Defense Ministry.
