Six Bulgarians convicted in London spying ring for Russia targeting multiple European countries, with sentences ranging from 5 to over 10 years.
A London court sentenced six Bulgarians to multi-year prison terms for espionage activities on behalf of Russia across several European countries including Germany, Austria, Spain, Montenegro, and the UK. The spy ring leader received a sentence of ten years and eight months. The group also targeted a military base in Germany. Jan Marsalek, the former Wirecard executive implicated in the financial services scandal and wanted by Interpol since 2020, was alleged to be the Moscow contact with close ties to the Russian military intelligence agency GRU. Thousands of messages between the alleged spy ring leader and Marsalek were part of the trial evidence. The defendants received significant sums of money for their espionage work.
Confidence: High
Article clearly describes a hostile Russian espionage operation involving a spy ring arrested and sentenced in London, linking Russian intelligence via GRU and a Moscow contact, representing hostile hybrid warfare activity inside Europe.
