YANBU, this programme was an eye opener for me and has really upset me.
I voted Brexit for many reasons, one of them being that I wanted our government to use some of the money saved to support UK farmers and produce more of our own food. UK farmers cannot compete on a level playing field in Europe, as UK farmers have higher animal welfare standards than other EU countries so they have higher costs. I also hoped that they would stop the export of live calves to mainland Europe (which used to travel via Dover but now have a much longer, more arduous journey via Ireland), because the calves fattened for veal over on mainland Europe are raised in terrible conditions that are outlawed in the UK. Now I find that we might be trading with a country that has even worse welfare and hygiene practices than mainland Europe, with pressure to stop labelling the country of origin on packaging - I really hope this doesn't happen.
People who voted Brexit had no way of knowing that 4 years later there would still be no workable trade deal with the EU. Brexit is unprecedented and is going to have unforseen consequences, but I still believe that in the long term the UK will be better off cutting free from the EU. Only time will tell.
