“Drugs devastate communities, line the pockets of serious criminals, and are a serious driver of the violence which ruin young lives right across the country,” said Ms Patel.
“We are sending a strong signal to criminals in the UK and abroad seeking to smuggle drugs into or through the UK – your efforts will fail and we will use every part of our law enforcement powers to stop drugs from coming into the UK.”
Border Force officers discovered the class A drugs after identifying “anomalies” with the cargo in the container during a routine inspection.
Tim Kingsberry, regional director for Border Force South, added: “This significant seizure has removed a large amount of dangerous drugs from the streets, which not only reduces the significant harm they cause to communities but also makes a huge dent in the profits of smugglers.”
