Brian May has continued his impassioned campaign against badger culling, branding the practice “morally indefensible” in a new documentary.

The Queen guitarist, who previously led a funeral parade through London in honour of badgers killed, and butted heads with Jeremy Clarkson over his beliefs, compared the method which some farmers use to avoid bovine disease spreading to a witch hunt.

In the BBC’s Brian May: The Badgers, the Farmers and Me, May explores what he considers the wasteful slaughter of cows and badgers, and a government policy which he feels has failed farmers.
