London (CNN) With less than 75 days until Britain is set to exit the European Union, a government report leaked to The Sunday Times newspaper reveals the disastrous effects a no-deal Brexit would unleash on the country.

The dossier also predicts the introduction of a hard border in Ireland, which has been a main sticking point in negotiations, and severe travel disruptions at UK ports that could last up to three months.

Medical supplies coming from Europe will be "vulnerable to severe extended delays," and the availability of fresh food will be reduced, causing prices to rise, the newspaper reported.
