FIRST Minister Alex Salmond has promised to negotiate with the rest of the UK in "comradely friendship" if there is a vote in favour of independence.

Mr Salmond said he isn't taking the result for granted, claiming Westminster leaders would change their position on sharing sterling if there was a Yes vote.

He said; "On Friday, when the Yes side have won this campaign, and I hope have won it with a decent margin, then you will find Westminster politicians singing an entirely different tune.

"The central mistake the No campaign has made is to actually tell people in Scotland it is not capable of running its own affairs financially.

"That message has been thoroughly rejected by Scotland and, whatever the result, this huge movement towards Yes is an outstanding feature of the campaign."

He said if there was a Yes vote, he would invite his political rivals to join Team Scotland to negotiate the terms of independence.

He added: "I shall be inviting people from across the political spectrum to be part of that Team Scotland so we can negotiate in comradely friendship with our neighbours."

Mr Salmond's comments come after a report from a centre-right think tank claimed Scottish nationalists have severely underestimated the economic risks of independence.

The Centre for Policy Studies said an independent Scotland would face three major risks in oil, finance and pensions.

Its report, titled Why Scots Should Say No, suggests the North Sea revenue for the Scottish government would fall from £10.1bn in 2011-12 to £3.7bn in 2016-17, some £3.2bn adrift of the £6.9bn predicted by the Yes campaign.
