Badger culling and mass badger vaccination are unsafe and costly practices that interfere with protected species.

The Zoological Society of London (ZSL) and Imperial College London say culling means infected badgers travel further as neighbouring setts are killed.

Are the shortcoming of existing cattle TB tests soon to be exposed by a simple, clever blood test that has been waiting in the wings? The development may shine light on practical compromises in the extended, failing fight against TB in England - at huge tax-payers expense. Biologist TOM LANGTON looks at a growing dilemma in the world of bovine TB cattle testing

Of 5,500 badgers to be shot during the pilot culls, only 240 will be independently monitored for humaneness, it has emerged. And just 4 Natural England officials will oversee the killing in Gloucestershire and Somerset

Government says vaccination on its own is not enough to stop the spread of bovine TB in cattle and announces plans to grant farmers culling licences
