Chris speaks with intelligence historian and journalist Trevor Barnes about the Bulgarian spy ring trial at the Old Bailey, one of the most significant espionage cases in the UK since the Cold War. Barnes attended the proceedings and walks Chris through how a network of Bulgarian nationals, allegedly directed remotely by fugitive Wirecard executive Jan Marsalek from Moscow, was tasked with surveilling journalists and dissidents across Europe — including Bellingcat investigator Christo Grozev — in operations that prosecutors suggested could have enabled kidnapping or assassination. The case cracked open after a US intelligence tip-off, was jointly handled by MI5 and the Met's Counter Terrorism Command, and ultimately turned on roughly 200,000 encrypted Telegram messages. Barnes unpacks what the trial revealed about Russia's growing reliance on proxy networks and criminal cut-outs in place of traditional deep-cover officers, and what it signals for Western counter-intelligence in an era of mounting state-sponsored threats.
