There are delays on the M25 after a car overturned between Junction 21a and 22, near to Radlett.

A car overturned at 3.16pm, causing lanes three and four to close at the time.

The Highways Agency say no-one was injured in the crash.

Everything caused by the incident was cleared by 16.04.

There is currently slow traffic going back to Junction 17.

When asked how long the delays are expected to last, the Highways Agency said it was difficult to say.

They predicted it should clear within 20 to 30 minutes, however the delays are expected to be exacerbated by rush hour traffic.

At which point, it will be difficult to judge what is caused by the crash, and what is caused by rush hour on the notoriously busy road.
