British Prime Minister David Cameron said he welcomed the outcome of the Scottish Independence Referendum, saying the winning 'No' vote was a 'clear result' for Scotland to remain part of the United Kingdom.

Cameron added that the result vindicated his decision to put a straight 'Yes' or 'No' to independence choice on the ballot paper.

"It was right that we respected the SNP's majority in Holyrood and gave the Scottish people their right to have their say. Let us also remember why it was important to ask the definitive question 'Yes' or 'No'. Because now the debate has been settled for a generation," he said.
