EU protectionism that the UK will be well rid of. It also includes the GMO scare tactics.
Nothing would save UK anymore Brexit or not. Just compare once mighty Sterling to most of EM currencies. It does worse economically than developing countries right now. A third world country in a making.
It doesn’t change the fact than cheaper US food is unfit for human consumption.
The GM bit is from the UK. And the British public want these rules.
