No idea what you are on about. Are you suggesting that Coronavirus is in some way connected to Brexit? An act of God sent to punish us for voting to leave ? If so he seems to have missed his target punishing the rest of the world for our act of defiance.
As for the farming business, what are you trying to say about that? That in the middle of a pandemic we should be flying in 70,000 people from throughout Europe to do the job? There are more than 70,000 unemployed people in the UK. The farmers and government need to get organised and use those, not to mention the additional hundreds of thousands (if not millions) who will probably be out of work for at least three months who will be desperate for the money.
You mat not have noticed, but whilst we have left the EU in name, nothing else has actually changed yet.
