Long delays are expected on the M25 this morning due to a car accident.

There is currently very slow traffic and an exit slip road is partially blocked on the M25 anticlockwise at J20 A41 in Kings Langley, with congestion running to J21a A405 in St Albans.

Police have blocked off the start of the exit slip road due to an accident involving a car, however traffic can still use the slip once they have passed the accident.

It is not known if there any injuries.
