I can't understand why we don't use our farms and farmers, support them with subsidies if necessary
Because they aren't posh ?
become self sufficient country with our own food.
Go back over 200 years then ?
I would pay more for food grown and produced in the UK by UK farmers to really high standards....
That's a nice decision to make on behalf of people who are already going hungry - let alone know where the next meal is coming from.
