PM Thought Of Quitting On Yes Vote
David Cameron has admitted he "contemplated having to go'' if Scotland voted for independence.
The Prime Minister, in an interview with the Sun on Sunday, said he would have been "heartbroken'' by the break-up of the UK and first considered his position when polls put the Yes campaign ahead just days before the referendum.
In the event, Scottish voters rejected independence by 55% to 45% and it was First Minister Alex Salmond who resigned, announcing hours after the result was declared that he would be stepping down in November.
Mr Cameron told the paper: "I thought about resigning because I care so passionately about this issue. If the vote had been for Scotland to have left the UK, I genuinely would have been heartbroken. I would have felt winded and wounded.
"Emotionally, one would have thought, 'I'm so saddened by this. I find it difficult to go on'.''
"Of course, I contemplated having to go. I thought, 'What's the right thing to do?' In many ways the easiest thing would be to say, 'I feel wounded by this' and walk away. I'm sure it would have been absolutely awful.
"In the end I came to the conclusion that would not have been the right thing to do.''
Meanwhile, a rally focusing on the call for a revote on independence will be held outside Holyrood this afternoon. More than 9,000 people have stated they plan to attend on the event's Facebook page.
