A diesel spillage on the A414 has sparked widespread traffic delays across Herts this morning (Wednesday).

The crash – which saw a lorry jackknife near London Colney – forced the closure of the road, causing problems across the county.

A police spokesman said: “There has been a significant diesel spillage which means that the road will be closed for some time.”

The crash took place at 2.13am, and the driver was not injured.
