So we already know things will get worse after enhanced checking at customs starts in October. Just two minutes research of the current views from business leaders finds this:
UK business leaders, when asked by The Herald last week whether they believed Brexit is damaging the economy, gave an emphatic response, with 75% saying “yes”.
The Food and Drink Federation, publishing the figures, noted the much-weaker picture for exports to the EU, it added overall sales of UK food and drink are down £2bn compared to pre-Covid levels, because of a sharp drop in sales to the EU. A combination of the ongoing impacts of the Covid-19 pandemic, and new barriers to trade resulting from the new trading arrangements, have led to a fall in exports to the EU of more than a quarter since H1 2019. Exports to nearly all EU member states fell significantly, including a loss of more than £0.5bn in sales to Ireland, while sales to Germany, Spain and Italy are each down around a half since H1 2019.”
UK construction sector growth slowed sharply in August, amid “formidable” supply-chain pressures fuelled by Brexit and the coronavirus pandemic, as material and staff costs went “through the roof”, a key survey has shown this week.
Expansion slowed last month across housebuilding, commercial property construction and civil engineering, the three sub-sectors covered by the survey from the Chartered Institute of Procurement & Supply and IHS Markit.
It is no wonder that business leaders, many of whom will be facing grim challenges on so many fronts caused by the European single market exit while having to navigate the extremely difficult fall-out from the pandemic, gave an emphatic “yes” when asked if Brexit was damaging the UK economy.
Or this from the Fishing Industry:
LONDON, July 14 (Reuters) - Britain's fisheries have been sold out by the post-Brexit trade deal agreed with the European Union, the head of an industry body said on Wednesday, urging the government to do more for the sector when a so-called adjustment period ends in 2026.
Winning back "control" of Britain's fishing waters was one of the main drivers for Brexit, with the industry becoming the poster child for many supporters of the country's departure from the EU during the 2016 referendum and beyond.
But Barrie Deas, chief executive of The National Federation of Fishermen's Organisations, said the government's assurances and promises made before striking a trade deal with the bloc late last year had been broken.
"It's really quite hard to convey how sudden was the fishing industry's fall from grace," Deas told journalists.
"The flags flying over our vessels for the last couple of years had a slogan which was 'fishing no sell out' and that really spelt out our fears. Those flags now seem both politically astute and prescient because that's what's happened."
He said there had been changes to quotas for fish "but at the margins", that the deal with the EU had emboldened other states such as Norway, and producers of some live shellfish had experienced real difficulties in exporting to the bloc.
Or farming:
Fruit and vegetables are being left to rot in England as Brexit deters migrants from taking up picking jobs.
Farmers have told Euronews that restrictions to freedom of movement have had a "devastating" impact.
Brexit -- the effects of which kicked-in at the start of the year -- means hiring migrant pickers from eastern Europe is now much harder.
So you see. Its business and industry leaders that are reflecting significant damage from Brexit not just a few having a moan on BlueMoon.
