A crash on the M25 this morning near Potters Bar has caused long delays.
The incident was at about 7am on the clockwise carriageway between Junction 24 for Potters Bar and 25 for Enfield, and resulted in one lane closure.
There was knock-on congestion tailing back beyond Junction 23 for the A1(M) and South Mimms.
A Highways England spokesman said the lane has since reopened and traffic has eased, but there are still delays on the stretch.
