Broken Britain?

The polls showing a large swing in support to the Scottish nationalists sowed panic in the British ruling elite. Cameron headed to Edinburgh on Wednesday where he begged Scots not to destroy the "family of nations" that makes up the United Kingdom.

In a hurried attempt to win back support for the union, the Labour Party rushed dozens of lawmakers to Scotland where it is the only political force that rivals the Scottish nationalists.

After two British banks - Edinburgh-based Lloyds and RBS - said they would shift their registered head offices to London if Scotland voted to break away, Salmond accused the British government of orchestrating a campaign by corporate lenders.

"Scotland is on the cusp of making history. The eyes of the world are on Scotland," Salmond, a 59-year-old former oil economist at RBS, told reporters in Edinburgh.

"Scotland will vote 'yes' next Thursday. And they'll vote 'yes' because last minute cobbled up promises from the 'no' campaign which unravel at the slightest scrutiny will not fool anyone in this country, and neither will blatant bullying and intimidation of the Westminster government."

The pro-independence camp says it is time for Scots to rule their own country and build a fairer society without being told what to do by a political elite in London whom they accuse of mismanaging Scotland's wealth.

The unionist campaign, supported by the three main political parties in the Westminster parliament, says Scotland is more prosperous and secure within the United Kingdom and says an independent Scotland would face serious financial and economic hurdles.
