Five Bulgarian nationals suspected of spying for Russia will be charged with conspiracy to conduct espionage, UK prosecutors said Thursday.
Three men and two women "will be charged with conspiring to collect information intended to be directly or indirectly useful to an enemy for a purpose prejudicial to the safety and interest of the state", the Crown Prosecution Service said in a statement.
The charges relate to alleged offences that took place between August 2020 and February 2023, the CPS added.
Orlin Roussev, 45, Bizer Dzhambazov, 41, Katrin Ivanova, 31, Ivan Stoyanov, 31, and Vanya Gaberova, 29, will appear at the Westminster Magistrates' Court in London on Tuesday.
Three of them -- Roussev, Dzhambazov and Ivanova -- were charged in February with "possession of false identity documents with improper intention", the CPS said.
