Geronimo the alpaca will be slaughtered after his owner lost a last-ditch High Court bid to save him. The animal has twice tested positive for bovine tuberculosis and, as a result, the Department for Environment, Food and Rural Affairs (Defra) has ordered its destruction. His owner Helen Macdonald, who imported him from New Zealand, believes the tests are returning false positives, but has been refused permission to have him tested a third time.
