The forecasts compiled by the Cabinet Office set out the most likely aftershocks of a no-deal Brexit rather than the worst-case scenarios, the newspaper said.

Hard border: The files show that, without a deal, the government believes that there will most likely be a hard border between Northern Ireland and Ireland (which will remain an E.U. member state), because current plans to avoid widespread checks will prove unsustainable.

Response: The British energy minister dismissed concerns over potential supply shortages in the event of a no-deal Brexit as “scaremongering.”

The cabinet minister in charge of no-deal planning, Michael Gove, said on Twitter that the leaked documents reflected “a worst-case scenario” and that the government had significantly accelerated its planning in the past three weeks.
