Sainsbury’s – Sainsbury’s do have a policy relating to provenance and traceability of the food that is on their shelves and make a general commitment to buy British (they do not talk about buying locally on their website). They say they want to work more closely with British farmers and that by 2020, they will double the amount of British food they sell. There is no commitment to buy British in their non-food areas. At least they are trying. I suggest you check where the things you buy are sourced and packaged. It is particularly good that on the Sainsbury’s website they give the country of origin for their own brand products (mostly only applies to their own brand products but that’s a good start) and they even sell British made kitchen pans. Well done Sainsbury’s.
