The M20 is going to be closed for nearly three hours after a multi car crash.

Kent Police roads unit said the road will be shut near Swanley after a safety barrier was damaged, needing repair.

Delays are expected in the area following the incident, reportedly involving five cars.

A diversion has been put in place following the closure, which is between junction three and junction one London bound.

Traffic is building while a large number of emergency services are on the scene.

Update: One lane has reopened but there are still long delays. 

More as we get it.
