For the past year Panorama has been filming with Kent police as they try to disrupt the ‘county lines’ that transport millions of pounds of drugs from London to towns across their county. With an estimated 1,000 county lines operating across the UK, criminals have increasingly turned to children and the vulnerable to carry out the risky job of distributing drugs. Despite months of lockdown, the illegal trade in class A drugs has flourished. Panorama films drug deals openly taking place on the streets, with police involved in a game of cat and mouse to pick off the street dealers while building the intelligence and evidence to go after those that supply them.
