The leaders of the three main British political parties have cut a deal to devolve more powers to Scotland if voters reject independence in Thursday's referendum.
The agreement, signed by David Cameron, Ed Miliband and Nick Clegg, promised to give the Scottish parliament permanent new powers.
It included a commitment to share the resources of the United Kingdom equitably and to continue the Barnett Formula, by which spending is distributed to constitutent nations of the UK according to their populations.
There was also a categorical undertaking to give the Scottish Parliament the power to determine health service funding including the ability to raise extra revenue for the purpose.
British Prime Minister David Cameron has made his final speech to Scottish voters before the independence referendum.
Mr Cameron has been in Scotland pleading for voters to remain a part of the United Kingdom.
Speaking in Aberdeen Mr Cameron said a 'Yes' vote for independence would lead to a "painful divorce" which would make foreigners of friends and family.
He said it could "end the United Kingdom as we know it", and argued there would be no way back if Scotland does decide to leave the United Kingdom.
"Why should we take one Great Britain and turn it into smaller, separate nations? What is that an answer to? How will that help? Let no one fool you that yes is a positive vision," he said.
Mr Cameron also said it would endanger Scottish pensions and the currency Scots use.
Scotland's First Minister and pro-independence leader Alex Salmond joined business leaders to argue for Scottish independence saying it will improve both the Scottish economy and society.
He used an event at Edinburgh Airport to hit out at what he called the scaremongering of the 'No' campaign.
On Thursday voters will be asked: "Should Scotland be an independent country?"
