A section of the M6 motorway was closed after two tankers collided and spilled 18,000 litres of chemical waste onto the road.

Firefighters were called to the scene on the northbound carriageway between junctions 18 and 19 at about 1.13pm on Friday.

Both lanes of the motorway near Knutsford, Cheshire, were closed while firefighters wearing breathing apparatus and protective suits used high-powered jets to apply water to the spilled cargo.
