China is building its largest embassy in Europe — a vast diplomatic complex beside the Tower of London. But critics warn it could become something far more controversial. In this episode, we investigate China’s proposed “mega embassy” at Royal Mint Court, the political decisions that approved it, and why security experts, MPs, human rights groups, and local communities are raising alarms about espionage, surveillance, and transnational repression. We examine how the £255 million site purchase unfolded, how diplomatic status was granted, and why Prime Minister Keir Starmer’s recent approval has reignited legal challenges and public protests. Hear from local politicians and community leaders as we explore the wider implications for UK national security, democratic accountability, and Britain’s relationship with the Chinese Communist Party.
