'Labour has said it is "more important than ever" that Parliament is recalled after the government published its no-deal Brexit assessment.
Shadow Brexit secretary Sir Keir Starmer said the Yellowhammer documentconfirms there are "severe risks" if the UK leaves the EU without a deal.
MPs forced the government to release the file before Parliament was suspended - or prorogued - on Tuesday.
The government said no-deal mitigations would be published in due course.
Sir Keir said recalling Parliament would allow MPs "the opportunity to scrutinise these documents and take all steps necessary to stop no-deal".
His comments followed a ruling by Scotland's highest civil court on Thursday that the government's proroguing of Parliament was unlawful.
The Yellowhammer file, which is redacted in parts and almost identical to a version leaked to the Sunday Times last month, says a no-deal Brexit could lead to:
- a "decrease" in certain types of fresh food and "shorter supply" of key ingredients
- price rises for food and fuel, which would "disproportionately" affect those with low incomes
- "disruption lasting up to six months" potentially affecting medicines and medical supplies
- protests and counter-protests across the UK
- lorries waiting for more than two days to cross the English Channel
The document also says some businesses could cease trading, the black market could grow, and some adult social care providers might fail.
Michael Gove, the cabinet minister with responsibility for no-deal planning, said "revised assumptions" will be published "in due course alongside a document outlining the mitigations the government has put in place and intends to put in place".'
