SCOTLAND’S BREXIT Minister Michael Russell has called on the UK Government to come clean over their “Doomsday” modelling and share their findings with Edinburgh.

Over the weekend it was revealed officials in David Davis’s Department for Exiting the EU had drawn up scenarios as part of their contingency planning, on what might happen if Britain crashed out of Europe without a deal.

Civil servants have modelled a mild reaction, a slightly more severe impact and another dubbed “Armageddon”.

The second scenario suggested Scotland’s supermarket shelves would be bare just two days after Brexit.

It suggested medicine and fuel would run out shortly after.

Russell told The National he had been asking Davis for this sort of modelling to be done, but had always been rebuffed.

“Now, less than a year to go until the UK proposes to leave the EU, we find out through newspaper reports that the sort of modelling we have been asking for appears to have been done and is so potentially challenging that it is alleged to have been locked away.

“Nothing about this is acceptable. If a hard Brexit might lead to food and fuel shortages in Scotland then the people of Scotland have a right to know. It is also imperative that the UK Government co-operates with the devolved administrations on its contingency planning as a matter of urgency.”

In a letter to the Brexit secretary, Russell said: “Food security and the operation of the health service and the Scottish transport system are central to the responsibilities of the Scottish Government. It is essential to the interests of all those we serve that we are meaningfully engaged in your planning on these and a wide range of other matters.

“I trust that there will be an opportunity for us to discuss as a matter of urgency how that can be made to happen, and I would therefore ask that this issue be added to the agenda of the next meeting of [the Joint Ministerial Committee].”

The report says the Port of Dover would, effectively, collapse on day one, and the up to 10,000 trucks that pass through each day could be forced to park along the motorway, stuck in interminable queues.

Around 17% of the UK’s entire trade in goods by value, and just 2% of the trucks passing through face customs checks. Bosses at the port say even just a two-minute delay in processing truck arrivals could cause a 17-mile line of traffic.

Yesterday, Davis’s department were sticking to the line they’d given the Sunday Times three days ago.

A Department for Exiting the EU spokeswoman told The National: “These newspaper reports are completely false. A significant amount of work and decision-making has gone into our no-deal plans, especially where it relates to ports, and we know that none of this would come to pass.”

Theresa May’s official spokesman told reporters that “none of this will happen”.

He added: “We have always been clear we are planning for all scenarios and we will be fully prepared.

“We are equally clear that we are working towards a deal because it’s in the interests of both sides.”

Meanwhile, the Supreme Court announced that they have scheduled July 24 and 25 to hear the UK Government’s case against Holyrood’s own Brexit Continuity Bill.
