Leaked documents show UK government thinks hard border will be likely under no-deal
Under no-deal, avoiding a hard border would be "unsustainable".
A hard border would be required on the island of Ireland in the event of a no-deal Brexit, according to documents leaked to The Sunday Times newspaper.
The paper reported that avoiding the return of the hard border would likely be "unsustainable".
The documents also say Britain will face shortages of fuel, food and medicine if it leaves the European Union without a deal.
The forecasts compiled by the Cabinet Office set out the most likely aftershocks of a no-deal Brexit rather than the worst case scenarios, said the Times.
The contingencies for no-deal show there will be "direct action" with road blockades.
"Compiled this month by the Cabinet Office under the code name Operation Yellow hammer, the dossier offers a rare glimpse into the covert planning being carried out by the government to avert a catastrophic collapse in the nation's infrastructure," the report in the Times read.
"The file, marked 'official-sensitive — requiring security clearance on a 'need to know' basis — is remarkable because it gives the most comprehensive assessment of the UK's readiness for a no-deal Brexit."
Johnson has repeatedly vowed to leave the EU on 31 October with or without a deal.
