There are big problems on the M25 in Hertfordshire after a lorry overturned last night.

A man's died after the accident just before the exit at junction 25 for Enfield at around 9:30pm - Police have closed the road off clockwise back to junction 23 for South Mimms and the A1M.

Stuart Evans from the Highways Agency has been telling Heart it involved a car transport:

"It was carrying around 10 vehicles and I believe half of the vehicles escaped from the transporter and were strewn across the carriageway. That caused significant damage to the barriers and took out two street lighting columns at the same time."

It's not clear when the road will be reopened as the carriageway has to be resurfaced.

We're being told that diversions are in place though as drivers exit the motorway at junction 23.
