Traffic is queueing on a six-mile stretch of the M25, after a broken down crane left a trail of oil on the carriageway today.
Highways England confirmed on Twitter the spill was caused by a crash on the M4 earlier today.
Travel time is around 35 minutes, as two lanes have been closed on the main carriageway near Leatherhead while the oil is cleared up.
This is a developing story which will be updated as and if we receive more information.
