Scottish independence: Salmond accuses 'bullying' ministers
Scotland's First Minister Alex Salmond has written to David Cameron to accuse his ministers of bullying behaviour.
He claimed recent interventions had been contrary to both the letter and spirit of the Edinburgh Agreement.
Earlier this week, UK Chancellor George Osborne said a vote for independence would mean walking away from the pound.
The Herald newspaper also quoted a "senior coalition source" saying a yes vote might not guarantee independence if talks did not go smoothly.
In the letter, Mr Salmond urged the prime minister to distance himself from such a position as quickly and publicly as possible.
Mr Salmond said: "Failure to do so will be interpreted, at best, as complicity and, at worst, endorsement of this deeply anti-democratic position.
"We remember how Scotland reacted to the poll tax, and we have seen the groundswell of reaction to the arrogance we have seen in the past week. I am calling on them to cease and desist."
Meanwhile, the leader of the Better Together campaign and former Chancellor, Alistair Darling, accused Mr Salmond of being a man "without a plan".
He said people in Scotland needed to know what currency would be in their wallet or purse if they left the UK.
He said: "With just over 200 days until the referendum Alex Salmond is running out of time to develop a plan for who would set our interest rates, control inflation and back-up our banks."
Mr Osborne's statement on currency union with an independent Scotland came in a speech in Edinburgh - a position echoed by Labour and the Liberal Democrats.
Mr Salmond accused the three main UK parties of "bluff, bluster and bullying", and said the move would "backfire spectacularly".
BBC Scotland correspondent Laura Bicker said it had been a key week in the referendum debate.
The Edinburgh Agreement was the deal in October 2012 between the UK and Scottish governments for a referendum on independence for Scotland.
