1. Emergency planning costs balloon as the government prepares for medical shortages

The Treasury this week announced a further £2bn in “Brexit preparedness” funding, to cope with the extra costs of a no-deal exit, taking the total to more than £4bn. At the same time, the health secretary, Matt Hancock, said he had “become the world’s No 1 buyer of fridges” as part of a plan to stockpile essential medicines.

2. Truck queues at Dover may back up for miles

Simulations by Imperial College and planning by Highways England have both forecast immobile freight traffic for tens of miles along the M20 caused by delays at Dover. Kent county council said this would lead to gridlocked and rubbish-strewn streets, unburied bodies and children unable to take exams.

3. Economic growth will take a hit of nearly 10%

The government’s own forecasts say that growth over the next 15 years without a deal will be 9.3% lower than it would otherwise have been.

4. Some major industries will be hamstrung

The example of how a crankshaft for a new Mini is made shows how car parts can cross the English Channel multiple times during the manufacturing process. Tariffs on these partial exports and imports, and delays to “just-in-time” production processes would make British factories much less appealing to carmakers.

5. UK exporters face annual tariff costs of more than £6bn

Guardian analysis showed that under WTO rules, British exports to the EU would be hit by tariffs of £6bn (roughly two-thirds of Britain’s net contributions). Imports were also likely to be affected, increasing the cost of living in the UK.
