Jurors were told of the convictions at the start of a trial of three other alleged spies.

Summary

Two Bulgarian men, Orlin Roussev and Biser Dzhambazov, have pleaded guilty to spying for Russia in the UK, admitting to conspiracy to gather intelligence for Russian benefit.

Their activities included surveillance of individuals and locations, using false identities, and advanced technology.

Three other alleged spies, currently on trial, deny similar charges.

Prosecutors described a coordinated operation directed by Roussev, who received orders from Jan Marsalek, an Austrian linked to Russian intelligence.

The espionage involved high-level deceit, including the use of “honey traps” to extract information from targets.
