Paramedics and police are currently on the scene of a major multi-vehicle pile-up on the A1(M).

The northbound carriageway was said to be “gridlocked” by one eyewitness and is causing delays on the road around Stevenage.

A Hertfordshire Constabulary spokeswoman told the Welwyn Hatfield Times: “Police were called just after 11am today following a collision on the A1(M), near Junction 6, northbound.

“Multiple vehicles are reported to have been involved.

“Paramedics are also on scene.”
