Delays are being reported on the M25 after “several vehicles” were involved in a crash this morning.

Highways England said at 6.43am one lane was closed on the anti-clockwise carriageway between J17 (Maple Cross) and J16 (M40 interchange).

It tweeted: “One lane is closed while we assist the fire brigade and ambulance service with a collision. Please plan ahead due to delays in the area.”

Another crash took place shortly afterwards, with one lane closed between J15 and J16 on the clockwise carriageway.

Highways England tweeted: “#M25 J15 to J16. One lane is closed due to a collision between several vehicles.”

All lanes on both carriageways have now reopened but drivers are being warned of delays still in the area.
