The Irish Kinahan cartel has significantly impacted the UK drug and gun trade over the past two decades, with police revealing its extensive operations. The cartel, valued at €1bn, is believed to control a substantial portion of the European cocaine market and has been linked to various crimes globally. A new BBC documentary explores the cartel's history and law enforcement efforts to dismantle it, highlighting key figures like Thomas Kavanagh, who was recently jailed for drug trafficking. Despite ongoing investigations, a lawyer for the Kinahans claims many allegations remain unproven in court.
