There are serious doubts about if, how and when an independent Scotland will take its place in the EU.
Today's White Paper on Scottish independence may be 670 pages long, but many voters still say they have unanswered questions.
ITV Border's Political Editor, Peter MacMahon, gives his reaction to the unveiling of the SNP's White Paper.
The 650 page document outlines details of the SNPs plans to take Scotland out of the United Kingdom if there's a 'yes' vote in next year's referendum.
Our Political Editor Peter MacMahon was watching the press conference in Glasgow:
First Minister Alex Salmond has said that excluding an independent Scotland from the sterling currency would leave a "massive hole in the UK balance of payments".
He told ITV News it would be in the interests of both governments to continue using the pound and that he expected Westminster to "live up to their side of the bargain".
A new Scottish Broadcasting Service (SBS) could initially be based on the staff and assets of BBC Scotland, according to the White Paper.
The SBS could then enter into a formal arrangement with the BBC, whereby it would supply it with programming in return for continuing access to BBC services in Scotland.
The White Paper says: "This will ensure the people of Scotland will still have access to all current programming, including EastEnders, Doctor Who and Strictly Come Dancing, and to channels like CBeebies."
While a Yes vote in next year's referendum would end the political union between Scotland and England, the paper stresses that the Union of the Crowns - which dates back to 1603 - would continue and Scotland would keep the Queen as its monarch upon independence.
"On independence, Scotland will be a constitutional monarchy," it says. "On independence in 2016 Her Majesty the Queen will be head of state."
Scottish First Minister Alex Salmond ends the press conference saying he thinks the journalists have had a "fair kick at the ball" and that he looks forward to answering many more of their questions in the months ahead.
The Leader of Better Together campaign, Alistair Darling, has given his reaction to the White Paper:
Nothing has changed as a result of this White Paper. The nationalists have ducked the opportunity to answer the big questions about Scotland’s future.
We have waited months for this and it has failed to give credible answers on fundamentally important questions. What currency would we use? Who will set our mortgage rates? How much would taxes have to go up? How will we pay pensions and benefits in future?
It is a fantasy to say we can leave the UK but still keep all the benefits of UK membership.
The White Paper is a work of fiction. It is thick with false promises and meaningless assertions.
Instead of a credible and costed plan, we have a wish-list of political promises without any answers on how Alex Salmond would pay for them.
As for the promises, they could deliver on childcare now.
– Alistair Darling, Leader of the Better Together campaign
Their excuse for not using the power they already have beggars belief - Nicola Sturgeon said they couldn’t act now because women would go to work and the tax they pay would go to the UK Treasury. That is our treasury, not that of a foreign country.
With so much uncertainty and unanswered questions about the cost of independence, leaving the UK would be a huge leap in the dark – especially when we know that devolution works for Scotland. We can have the best of both worlds – a strong Scottish Parliament with the strength and opportunity of being part of a bigger United Kingdom.
The Better Together campaign, led by Alistair Darling, is countering the independence plans detailed in the White Paper.
Sturgeon's line on childcare astonishing, complaint is that women would get jobs & pay tax to HMT - that then transfers money back to Scot
Astonishing that at the centre of the Nationalist manifesto for separation is a proposal that can be delivered now with devolution #indyref
