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."
David Cameron has condemned Scottish nationalists as "wrong and irresponsible" for dismissing warnings about the political consequences of the upcoming referendum as a "south of the border conspiracy".
Addressing the Scottish Conservative party conference, the Prime Minister said the warnings about an independent Scotland's currency and place in Europe were necessary with citizens ready to make a "major life changing decision".
Prime Minister David Cameron will address the Scottish Conservative Party conference being held this week at the Edinburgh International Conference Centre. The referendum on Scottish independence is expected to be high on his agenda.
Speaking at the opening of of the Scottish Conservative party's spring conference in Edinburgh, the prime minister is expected to say the referendum is "a major life decision" that shouldn't be made without knowing the full consequences.
He is expected to add:
And look at who's laying out those consequences: the governor of the Bank of England, the president of the European Commission, business chiefs from companies like BP and Shell; Alliance Trust and RBS; Lloyds, Barclays - the list goes on.
These are not political puppets, they are serious, non-partisan figures.
So, the idea that these are empty warnings and political scare-mongering is a myth - and we owe it to the people of Scotland to take that myth apart.
David Cameron will focus on his fight to keep Scotland in the UK as he opens the Scottish Conservative party conference later today.
He is due in Edinburgh, where he will draw on recent interventions from major businesses, such as BP and Shell, in the referendum debate.
Mr Cameron will attempt to tackle accusations of "scaremongering" over the country's future, saying he wants to "take that myth apart".
