A major UK motorway has partially closed after a nightmare crash between a car and a tanker.
Emergency services rushed to the M1 following reports of a collision which led to a tanker being overturned.
Motorists have been warned over travel disruption due to the issue and have been told to expect lengthy delays.
Motorists have been issued an update following a 'significant spillage' on the motorway.
Drivers have been told to expect more delays after a spillage was seen coming from the tanker.
