A car crash and diesel spillage on the M25 is causing traffic jams by Potters Bar this morning.
One lane currently remains closed on the anti-clockwise carriageway towards St Albans, between junction 25 at Enfield and junction 24 at Potters Bar.
Highways England estimates delays of at least half an hour in the congestion, which is stretching back four miles towards the M11. More information on this as it becomes available.
