It was mildly amusing at first, Brexiters La La-ing, fingers in ears ,'there are no shortages'. Now this ignorance and refusal to believe facts its worrying, because there ARE shortages on Supermarket shelves. I've been to three Supermarkets last week and everyone had shortages: Tesco, Sainsbury's & Aldi. Aldi was the better stocked I have to say, but there were still shortages.
These are not important shortages that will cause hunger or distress (unless you can't live without frozen green beans or bisto chicken gravy) but there ARE shortages. Get over it! They have not been caused by one thing, but a perfect storm of Covid, a shortage of pickers/packers and dispatches due to Brexit visa rules, and an ageing UK HGV population that was not addressed when it should have been 5 years ago.
Some things will sort themselves out eventually, and some (visas to allow EU workers back into the UK for example) will be resolved by Boris making a massive U turn in his Exit strategies.
The EU are giggling behind their European flag as the UK squirms and comes begging for their workers back, while other countries who perhaps were flirting with the idea of leaving, are meekly looking at the floor shuffling their feet and wondering if it was such a good idea after all.
