Motorists planning on using Britain’s busiest motorway have been warned of long delays after an earlier horror crash overnight in which a man was killed.
The incident happened on the M25 last night at around 10pm when a silver BMW Z4 left the road before returning to a full stop on the carriageway, when it was hit by a blue Nissan Note. The driver of the BMW, a man in his 30s, died in the incident, which has continued to cause havoc this morning. National Highways warned drivers in the area to “expect delays” owing to the closure of the clockwise lane between junctions 3 for Swanley and junction 4 for Orpington in Kent.
