The M1 northbound near Bricket Wood has reopened after two people died - one of whom reportedly fell from a bridge.

A spokesman for the East of England Ambulance Service (EEAST) said two ambulances, an emergency response vehicle and an air ambulance were dispatched to the scene but stood down after midday.
The northbound carriageway was closed for several hours before reopening just before 4pm.
