Border Force says it has seized a record 12 tonnes of cannabis worth about £139 million in what it describes as the largest-ever UK bust. The drugs are reported to be hidden inside two shipping containers arriving at Southampton Port from Canada. Authorities say the containers contain around 1,200 boxes of cannabis. The Home Office statement cited by several outlets indicates the seizure is part of efforts to intercept illegal drugs entering the UK via maritime routes. The reports agree on the key operational details: the quantity of cannabis, its estimated street value, the shipment origin (Canada), and the port of arrival (Southampton). While outlets emphasize the “biggest ever” nature of the seizure, they provide the same basic facts about how the drugs are concealed and the scale of the consignment. No further information about arrests, charges, or investigation progress is included in the provided excerpts.
