DAVID Mundell is certain he would prefer a no-deal Brexit to the demise of the United Kingdom. And while we always knew of the Scottish Secretary’s opposition to independence, today, it seems, we can be in no doubt as to how strong that opposition is.

Over the past six months or so, a series of independent expert reports and statements have set out the dire consequences of the UK quitting the European Union without any agreement over what form the future relationship should take.

First, of course, there would be the impact on the economy, jobs and consumers. Crashing out without a deal would mean the UK and the EU would have to trade under World Trade Organisation rules. That would lead to tariffs being imposed on goods being imported and exported between the two.

According to Scottish Government analysis published in January, a no-deal Brexit will slow down the economy by about £12.7 billion a year by 2030, equivalent to a reduction of 8.5% in GDP or £2263 a year per person.

Those figures were broadly confirmed by the UK Government’s own analysis, leaked a few weeks later, which predicted Scotland’s economy would grow 9% more slowly than if it stayed in the EU.

An earlier study by the Fraser of Allander Institute at Strathclyde University forecast that 80,000 jobs would go in Scotland over the next decade if the UK tumbled over the Brexit cliff edge.

Consultants Oliver Wyman were also deeply pessimistic, forecasting that price rises resulting from a no-deal exit could cost UK households £1000 a year, with the impact disproportionately felt by poorer households. But food price hikes mighty be the least of the UK’s problems.

An analysis by civil servants in June warned of major supply problems. The contingency preparations leaked last month predicted the UK would be hit with shortages of medicine, fuel and food within a fortnight if it left without a deal.

The National:

The doomsday scenario drawn up by Whitehall officials forecast that the port of Dover, above, could collapse “on day one”, supermarkets in Cornwall and Scotland would run out of food within a couple of days, hospitals would run out of medicines within two weeks and fuel supplies would run out by the end of the first week.

On top of job losses and shortages of basic essentials, there is also the impact on security to consider. A report by the House of Lords European Union Committee warned a no-deal departure “would bring UK-EU cooperation on matters vital to the national interest – such as counter-terrorism, police, justice and security matters, nuclear safeguards, data exchange and aviation – to a sudden halt”.

The Lords analysis also said crashing out would place in jeopardy the status of about 1.3 million UK nationals in the EU, and 2.9m EU nationals in the UK.

It raised major concerns, too, about the Irish border, warning a no-deal outcome would bring customs posts back the volatile communities on the dividing line between Northern Ireland and the Irish Republic.

Drew Harris, deputy chief constable of the Police Service of Northern Ireland, told the Commons’ Brexit Committee last December that this would provide a target and a rallying call for the IRA, sparking a recruitment drive for dissident terror groups.

But for David Mundell all these scenarios are still preferable to Scotland becoming independent.
