Emergency services remain at the scene of an overturned tanker which has closed part of the A12. 

The vehicle overturned on the Copdock Interchange roundabout at around 4.30am this morning.

Suffolk Police called it a serious road traffic collision.

The ambulance service and seven fire appliances also attended.

A spokesman for the fire service said the road is expected to be closed for much of the day.

National Highways says the A12 northbound is closed between Junction 32B and the A14 at Junction 55 at Copdock.

Highways had tweeted there had been a "significant oil spill" but shortly before midday reported there had been no spillage.

The A14 remains open. 

Just before 4pm Suffolk police said the tanker driver, a man in his 50s, had been pronounced dead at the scene.

A police spokesman said the road would remain closed "for some time" and encouraged any witnesses or drivers with relevant dashcam footage to come forward.
