An overturned trailer on the M25 is causing severe delays.

Two lanes are now closed and travel time is more than 60 minutes after a vehicle overturned on the anticlockwise carriageway between Junction 16 (M40) and Junction 15 (M4).

Initial reports were that a lorry had overturned, however the Highways Agency is reporting that the vehicle on its side is a trailer which was being towed by a lorry.

Motorists are experiencing severe delays due to the overturned vehicle in lane one, of four.

Recovery work means two lanes are blocked.
