Polling has revealed that the appetite for Scottish independence has fallen since last year's referendum.
The survey of 1000 adults by Panelbase for the Sunday Times showed 42-percent of voters would vote 'Yes' to independence if a referendum was held tomorrow, down from 45-percent in September.
A collapse in oil prices - which were a key component of the nationalist argument - is believed to have alienated some former Yes voters.
Meanwhile, leaders of the four main parties in Scotland are taking part in another televised debate. Nicola Sturgeon for the SNP, Lib Dem Willie Rennie, leader of the Scottish Tories Ruth Davidson and Jim Murphy from Scottish Labour go head to head at 11.35am on BBC1 on Sunday morning.
Across the country, Sturgeon will meet former Labour supporters in Paisley who have dissented to the SNP.
Labour is focusing is on pensions - Jim Murphy says that under SNP plans for full fiscal autonomy (full financial control of the Scottish economy by Holyrood), pensioners will be £1000 per year worse off.
The Conservatives say voters back them on welfare cuts, and the Liberal Democrats are challenging the SNP not to hold another independence referendum.
