SNP Constitution Secretary Angus Robertson will set out his government’s plans for an independent Scotland to become an EU member state – pointing to “shared European values”. 

Mr Robertson will highlight how an independent Scotland would trade with the rest of the UK and Europe and insist that EU membership would be of “immense value” to the nation after separation.

The Scottish Government is publishing an updated case for independence, despite the route to achieving separation looking bleak.

Ahead of the launch of the latest chapter in the policy papers, Mr Robertson claimed the success of independent EU countries like Scotland demonstrated the immense value of being part of the world's largest single market.

Mr Robertson suggested that Westminster's disastrous Brexit-based economic approach, supported by both Labour and the Conservatives, had failed Scotland and driven down living standards.

He added that by joining a market seven times the size of the UK in the EU, new opportunities would open up for people and businesses in Scotland, despite most of the country’s trade being done with the rest of the UK.

Questions have been consistently raised about the ability of an independent Scotland to easily join the bloc, particularly over national debt a newly independent country is likely to carry.

But the latest paper in the Building a New Scotland series, to be published today, will say Scotland will use the tried and tested route to EU membership - the "article 49" process.

Mr Robertson said: "Independent EU countries like Scotland are wealthier and fairer than the UK, so with all our resources and talents why not Scotland?The Herald:

"People in Scotland voted overwhelmingly to remain in the EU but as on so many other occasions our views have been ignored by Westminster.

"Both Labour and the Tories are happy to impose a disastrous hard Brexit on Scotland which the UK Government's own fiscal watchdog thinks will cut national income by 4% compared with EU membership - wiping around £100 billion from the UK economy and leaving people on average earnings £1,300 a year worse off. 

"Today the Scottish Government is setting out an alternative direction for Scotland which will detail our shared European values, how we will trade with the rest of the UK and the EU, the immense value to Scotland of being a European Union member state and the contribution we would make to achieving the EU's goals.

"There will of course be challenges, and the tried and tested accession process to go through, but we can escape the costs of Brexit and build a new and better relationship with our friends on these islands: taking advantage of new opportunities as part of the EU and the world’s largest single market, which is seven times the size of the UK.”

A UK Government spokesperson said: “People in Scotland want both their governments to be concentrating on the issues that matter most to them, like growing our economy, halving inflation and improving public services.

“We want to work constructively with the Scottish Government to tackle our shared challenges because that is what families and businesses in Scotland expect.

“This is not the time to be talking about distracting constitutional change.”
