The North East of England may not have a vote in the Scottish referendum, but it does have a view.
Both the Scottish and UK Governments have been criticised for not giving Scottish voters enough information ahead of the 2014 referendum.
Businesses in the North East fear an independent Scotland could suck money and jobs across the border.
The Scottish First Minister Alex Salmond said his government plans to investigate building high-speed rail links between Scotland and the North of England.
He made his speech in Carlisle. He said public spending on transport infrastructure was £2,700 per head in London and only £5 per head in the North East of England.
Councils from both sides of the border are meeting for the first time today to discuss the economic future - if the people of Scotland vote yes in September's independence referendum.
The five cross border councils, which includes Northumberland County Council, will meet in Peebles.
The Scottish government announced the launch of the initiative last August after Northumbria University published the Borderlands report.
The report encouraged local authorities on both side of the border to work together to exploit mutual economic and social links.
In six months time, the people of Scotland will decide whether or not to remain part of the UK. But the powers they decide on directly affect the powers the North East will be left with.
Without Scotland's contingent of Labour MPs, a Conservative government in Westminster would become much more likely - which could leave the North East, largely a Labour heartland, with less of a voice.
Political Correspondent Paul Brand reports:
The North East of England may be affected more than most other regions of the UK by Scottish independence, if the people of Scotland choose to vote Yes in the referendum in exactly six months time.
Political Correspondent Paul Brand looks at the economic impact on the North East:
David Cameron has been speaking to ITV Border's Scotland Political Editor Peter MacMahon at the Scottish Conservative Party conference.
When asked whether there would be border controls between Scotland and England this was Mr Cameron's response.
The Sedgefield MP Phil Wilson has warned his colleagues that Scottish independence would damage the economy of the North East of England, as he led a debate into the issue at Westminster.
He said the effect of Scotland leaving the UK after September's referendum would reduce trade and travel, affecting workers and business from both countries. However, the Scottish National Party called the claims "scaremongering".
Watch Phil Wilson MP (Labour) and Angus MacNeil MP (SNP) in the debate:
It could be one the most important documents in the history of the country.
The Scottish government has finally published its vision for an independent Scotland.
It reveals how the country could develop if Scots vote yes in next year's independence referendum.
The SNP says it would keep an open border with England, but listed a number of policies to attract more business to Scotland.
Dan Ashby looks reports.
The Scottish Government says if the country went independent, it would aim to have an open border with Northumberland and keep the pound.
Today, November 26, it published its vision for independence, which also included a commitment to lower corporation tax.
But one business in Alnwick said it would not be tempted to move north of the border.
The SNP has published a 670-page White Paper setting out its plans for independence.
The long-awaited document includes a wealth of policy details.
If in power in an independent Scotland, the SNP would roll back many of the UK Government’s policies including the so-called ‘bedroom tax’, Universal Credit and the married couples tax allowance.
They would also slash air passenger duty by 50 per cent and corporation tax by three per cent.
