Commuters are facing hour-long delays on the M25 as Friday evening rush-hour traffic has been worsened by an earlier accident.
Seven miles of traffic is being reported after one lane was closed off following a brief accident at the Dartford Crossing.
Although all lanes have been reopened, traffic is still extremely heavy due to earlier congestions.
Congestion is being reported as far back as Junction 4.
More as we get it.
