Buy British and eat the seasons.
When is it going to sink in that we do not produce enough food to feed our population? We won't be able to 'buy British' if there's no 'British' to buy.
I know that we import food from other countries but our trade agreements with them are made through the EU and if we leave with no deal the agreements lapse and we have to go onto WTO tariffs, which will make imported food very expensive. If we start letting it in with no tariffs, under 'Most Favoured Nation' we have to let it all in regardless of standards (because standards are part of trade deals and we won't have any trade deals).
So no food standards. Lovely...
And our farmers go out of business because they can't compete with cheap imports.
Of course, all you clued up Leavers calling for 'no deal' knew that this would happen, didn't you?
