A PASSENGER has told of the moment a car burst into flames on the M4 approaching Newport last night.

The incident, which happened shortly before 5.30pm, between junctions 23 (M48, Chepstow) and 23a (Magor Services), caused severe traffic delays.

Robbie Priddle, a passenger in the 2008 Ford C-MAX, said: "Smoke started coming out of the bonnet, so we pulled over.

"We saw black smoke, followed by flames, and we got out of the car.

"Police and fire services arrived within 20 minutes. We're all fine, with no injuries."
