Helen Browning is an organic farmer and Chief Executive of the Soil Association. For one very lovely summer's day, she was also our host and tour guide at her mixed organic farm in Wiltshire - introducing us to pigs, piglets and cows on the way.

We ask Helen what organic farming really is, why the produce costs so much, and her views on Brexit, Michael Gove and pig slaughter.
