No politicians, economists or even journalists are now saying that Leaving will bring benefits, boost the economy and lead to great prosperity, investment, boom and growth.
The most common explanations of leaving without an agreement include the following consequences:
Long term no deal will trigger a deep recession with more damaging consequences for the UK economy than the 2008 financial crisis. Estimates vary but we are looking at losing around 9.3% of GDP.
Without a bilateral trade deal with the EU, Britain will follow World Trade Organization (WTO) rules.
UK exports would face the same customs checks and tariffs as other third countries outside of the EU.
The overnight end of frictionless zero-tariff trade will increase the price of many goods and
• create chaos at the borders
•drive up food prices
•lead to a shortage of some essential goods.
Even research carried out by the Brexit department said without deals on customs and trade, parts of Britain would run out of food and some medicines within a fortnight.
Health Secretary Matt Hancock warned medical drug companies to expect six months of “significantly reduced access” to the main trade routes between Britain and Continental Europe .
Dominic Grieve warned that a no-deal Brexit would be “absolutely catastrophic” for the UK.
“We've got to be realistic about this,” he told Sky News. “We will be in a state of emergency.”
•In its report, Kent County Council also warned:
“Refuse could be left outside homes and food deliveries be disrupted as the county copes with 10,000 lorries clogging up its roads”
“Bodies may remain uncollected and children might miss exams due to gridlocked roads in the event of a no-deal Brexit”,
Amazon UK chief Doug Gurr predicting that Britain will descend into “civil unrest” within weeks if it leaves the EU with no trade deal in place.
