THE M40 is closed between three junctions after a 40-tonne lorry jacknifed and shed its cargo this afternoon.

Southbound drivers are being diverted onto the A40 between junction 8a, south of Oxford, and junction six at Watlington.

Traffic is queuing and drivers are warned to expect delays.

The lorry, which hit the central reservation shortly before 1pm, is currently on its side across lanes two and three.

Its cargo of thermal insulation has been scattered across the all three lanes and there is diesel on the inside lane.

Police and the Environment Agency are currently on the scene.

It is not known when the road will reopen.
