A leaked cross-government study warning of the impact of a no-deal Brexit outlines a “worst-case scenario”, cabinet minister Michael Gove has said.

Details from the dossier warn of food and medicine shortages if the UK leaves the EU without a deal.

Mr Gove, who is responsible for no-deal preparation, said the document was old and Brexit planning had accelerated since Boris Johnson became PM.

But he acknowledged no deal would bring disruption, or “bumps in the road”.

The leak comes as Mr Johnson is to meet European leaders later this week.

The prime minister will insist there must be a new Brexit deal when he holds talks with German Chancellor Angela Merkel and French President Emmanuel Macron.
