A protection zone has been set up in Suffolk after government vets confirmed bluetongue disease was circulating in the UK and was classed as an outbreak.

Deputy chief vet Fred Landeg said test results had shown the disease, which is transmitted by biting midges, was passing between livestock.

So far there have been five confirmed cases of the disease. All the animals which tested positive have been culled.

The zone will be a minimum of 150km (93 miles) around infected premises.

A stricter 20km control zone has also been set up around the known bluetongue cases, with restrictions preventing animals being moved out of both zones.
