Two people have been killed after a lorry crashed through the central reservation on the A14 and collided with another oncoming lorry.
The fatal accident happened on the Leicestershire border this morning, at about 6.20am.
The accident caused hours of delays for motorists travelling on the M1 in Leicestershire, near the Catthorpe Interchange.
Police say a white Volvo LGV was travelling eastbound on the A14 in lane one, between Junctions 1 and 2. For reasons unknown, the lorry moved into the second lane and went through the central reservation, onto the westbound carriageway, where it collided with a black Leyland LGV.
The driver of the Leyland died at the scene of the collision.
The driver of the Volvo was taken to University Hospital Coventry, where he later died.
Drivers were diverted around Market Harborough whilst emergency services dealt with the incident.
Police are appealing for any witnesses to the collision to come forward with information, or for anyone who may have dashcam footage to get in touch.
Police are also asking the driver of dark or black saloon car, possibly a BMW, which was travelling eastbound towards Kettering, to get in touch, as they may have witnessed the collision and have information useful to the investigation.
