A van fire on the M25 saw all lanes closed this morning - and there are still delays while emergency services are on the scene. 

There is currently one lane closed and queuing traffic on the clockwise carriageway between junction 16 for the M40 and junction 17 for Maple Cross. 

Congestion goes back to junction 15 for the M4 and travel time is currently around half an hour. 

Lane one of four is still closed around half a mile after the viaduct. 

Traffic was halted completely whilst the flames were extinguished, but two lanes reopened at 9.50am and the third at 10am.
