There are long delays on the M5 due to a police incident.

Avon and Somerset Police are on the scene of the incident near junction 18 of the southbound carriageway.

Drivers heading southbound on the M5 are not able to leave the motorway at junction 18A. They will need to continue to junction 19 and head back northbound.

Drivers on the M49 are unable to join the M5 while the road closure is in place.

People heading to England from Wales are being diverted along the M4 to the Almondsbury Interchange where they can head south on the M5.

Highways England earlier reported four-mile tailbacks on the M5 back towards junction 17 as a result of the incident.
