A lane of the M25 has been shut anti-clockwise - with traffic moving very slowly - after a car erupted into flames close to J2.

Traffic is being caught up in delays and one lane is closed two miles before the Dartford Tunnel, following the fire at the A2 junction.

Congestion stretches back to J3 for the M20.

Meanwhile there is queueing traffic on the opposite carriageway as a result of the car blaze, but all lanes are now open.
