Are people hunting 'canned lions' in South Africa?

The World Conservation Congress has backed calls to push South Africa to ban the hunting of lions bred in captivity – and something known as “canned lion” hunting.

South Africa is the world's biggest exporter of animal heads - mainly to hunters who pay thousands of dollars to hunt lions and take their heads home as trophies.

Cameraman Derek Cobbett has shared his footage of a "canned lion" hunt with the BBC.
