The UK government will begin advising people, businesses, and other groups about how to plan for the possibility of leaving the EU without a deal.
Ministers say publication of the first batch of documents will tackle what they call “hair-raising scare stories” about a no-deal Brexit.
They say reaching a deal with the EU is the “overriding priority” but “we must be ready to consider the alternative”.
The EU has already produced 68 notices on “Brexit preparedness”.
Labour said a no-deal outcome would be “catastrophic” and a “complete failure by the government to negotiate for Britain”.
The party’s Brexit spokesman Sir Keir Starmer told Radio 4’s Today programme the government was “now moving into panic mode” and this latest advice would not reassure anyone.
