A TWO-car crash is causing delays on the M4 this afternoon.

The incident happened on the westbound carriageway between junctions 15 and 16 at around 11.25am today.

Cameras show the vehicles have collided with the central reservation barrier and one of the cars is overturned.

Fire and emergency services are on the scene.

A Wiltshire Police spokeswoman said: “It involved a red Ford Focus and a grey BMW, and although nobody is believed to be seriously injured, the carriageway is currently blocked.

“We would ask people to please be patient while we arrange for the vehicles to be recovered.”

Traffic is building up near the White Hart roundabout.
