The leaders of the three main parties in Westminster have signed a letter promising "extensive new powers" for Scotland if they reject independence in Thursday's referendum.
In a letter titled "The Vow" published on the front page of the Daily Record, David Cameron, Ed Miliband and Nick Clegg say a No vote will guarantee "faster, safer and better change than separation".
One story dominates Thursday's front pages with some newspapers printing emotive pleas to voters to keep the United Kingdom as one.
In Edinburgh tonight you can hear it and feel it. The buzz, the banter of the day and the thrilling sense something big is coming tomorrow.
There is nervousness, anxiety and on the streets of Edinburgh fuelled by an atmosphere unlike anything seen before in recent UK politics.
