David Cameron has told the Scottish Conservative Party conference in Edinburgh there will be 'no going back' if Scotland vote yes for independence.
"Six months from now the day will dawn , the polling booths will open, the voters will come out and the people of Scotland will decide - stay or go.
"Stick with the UK or walk away.
"If the Scottish people vote Yes in September, then Scotland will become an independent country, there will be no going back, no second chances."
"We face a monumental battle to keep our United Kingdom together."
