What is County Lines Defence?

County lines is a drug supply model that uses a dedicated phone line and a network of individuals — often young or vulnerable people — to distribute drugs from urban centres to smaller towns. Many defendants in these cases were coerced or exploited rather than acting freely.

Many county lines defendants are victims of exploitation. The modern slavery and trafficking defence — and the statutory defence under the Modern Slavery Act — can be determinative if the exploitation is established. The urgency is identifying that dimension of the case before the first court appearance.

Modern Slavery Act

Exploitation can be a complete defence.

Where someone was forced into carrying drugs, recognising the exploitation early can change the case.

How a county lines case proceeds

These cases are built from phone and location data linking a controlling line to the movements of the people carrying drugs. Arrests often happen at an address that has been taken over from a vulnerable occupant, or during a journey between towns.

The charges are usually supply or conspiracy and are heard in the Crown Court, where sentences for those running an operation are severe. For the young or vulnerable people used as couriers, the most important early step is identifying whether they were exploited rather than acting freely.

How the defence is built

Where a person was coerced or trafficked into carrying drugs, there is a statutory defence for those compelled to offend through exploitation. Establishing it can be decisive, and it can be supported by a formal referral that assesses whether someone is a victim of modern slavery.

The threshold is more protective for children than for adults. Beyond that defence, role still matters: someone directed as a runner is in a very different position from an organiser, and the evidence of exploitation, coercion, and background all bear on how the case is resolved.

Common questions

What is the modern slavery defence for county lines?
It is a defence for people who committed an offence because they were forced to through exploitation or trafficking. If it is established, it can prevent a conviction altogether. Whether it applies depends on the individual’s circumstances.
How do I know if the exploitation defence applies?
It depends on how the person came to be involved: whether they were coerced, threatened, or controlled, and how old they are, since the protection is stronger for under-18s. A formal assessment can help establish it, and that process can be started early.
What is cuckooing?
It is where a gang takes over the home of a vulnerable person and uses it as a base for dealing. Recognising that someone was a victim of cuckooing, rather than a willing participant, can change the whole direction of their case.
My child has been arrested — what should I do?
Call as early as possible, and raise any sign that they were pressured or exploited before the interview takes place. Children drawn into county lines are often victims first, and that has to be identified from the outset. A parent or guardian can be present.
