A section of the M25 has been brought to a total standstill following a road accident.
According to National Highways, four lanes have been closed on the anticlockwise side of the motorway between junction 25, Waltham Cross and junction 24, Potters Bar.
At the time of publication, all we know is that there has been a road traffic collision involving multiple vehicles, with delays of more than an hour from junction 24 onwards.
On the National Highways website, it suggests that the incident will not be cleared until at least 7.45pm, and on X a spokesperson added that an air ambulance has been called to the scene.
