MOTORISTS have been warned of delays on the M1 because a vehicle has overturned.

Two lanes are now closed on the M1 Southbound beween Juction 36 at Tankersley and J35a because of the accident.

There's a further delay on the Southbound carriageway between Junction 34 and Junction 31 because of an earlier accident - average speed has been reduced on that section to 20 miles an hour.
