Prime Minister David Cameron and Scottish First Minister Alex Salmond have signed an historic agreement enabling Scotland to hold a legally-binding referendum on independence.
The deal stipulates that the referendum will take place in autumn 2014 with a single Yes/No question on Scotland leaving the UK. It also allows 16 and 17-year-old to vote.
ITV's News' Scotland Correspondent Debi Edward reports:
After the signing, Mr Cameron told ITV News he "passionately" believes Scotland should remain part of the union.
He said, "This United Kingdom can never hold a country within it without its consent. We're better off together, but now people will have the choice".
Mr Salmond told reporters he was doing his "absolute best not to look triumphant".
The Scottish First Minister called today "an historic day for Scotland", saying the agreement "paves the way for the most important decision that our country of Scotland has made in several hundred years".
