3pm UPDATE:

Original story:

A LORRY has jackknifed on the M5 southbound near junction four and is across all three lanes.

Motorists are being warned to expect long delays, with the lorry just after the A38 (Bromsgrove/Stourbridge) slip road.

Two fire engines and police are on the scene, with traffic being diverted via the exit slip road, up to the roundabout and back on the M5 using the entry slip.
