Summary

A BBC investigation has named Bulgarian nationals Cvetelina Gencheva and Tsvetanka Doncheva as key figures in a Russian spy network previously operating from the UK.

Gencheva, an airport worker, exploited her access to obtain private flight details of the cell’s targets, even coordinating with convicted spies in Berlin.

Doncheva conducted surveillance in Vienna, including on a journalist, and engaged in anti-Ukraine propaganda.

While six other network members await sentencing in the UK, Gencheva and Doncheva have not been charged.
