====================

ESSEX Police are appealing for information following a serious collision on the M11.

One vehicle – a blue Nissan Almera – was involved on the northbound carriageway between Junction Six for Epping and Junction Seven for Harlow shortly before 7.40pm today (Thursday 1 January).

The road is likely to be closed while emergency services respond to the collision and investigate what has happened.

There was a less serious collision on the other carriageway at around a similar time but we believe that was a separate incident.
