Britain will be `fully prepared' for no deal exit from EU

The Sunday Times reported that models for mild, severe and "armageddon" reactions to no-deal exits were created by officials, with a source saying that even the severe scenario saw the Port of Dover "collapse on day one".

But the prime minister's official spokesman said: "The Department for Exiting the European Union has said that these claims are completely false.

"A significant amount of work and decision-making has gone into our no deal plans, especially as it relates to ports, and we know that none of this would happen."

Asked if that was a "cast iron guarantee", the spokesman said: "We are planning for all scenarios and we will make sure that we are fully prepared in the event of any eventuality."
