Two new polls have been released on the eve of the Clash of the Cabinets in the north-east - with fieldwork carried out in the wake of George Osborne's warning on the pound.

An ICM poll for Scotland on Sunday indicates support for independence has stalled while backing for the union has returned to previous levels.

Some 37% told that they will vote Yes against 49% who said they will vote No.

The most significant factor in the latest poll is the swing from those who say they "don't know" towards voting No.

An ICM poll in September found 32% support for Yes, 49% support for No and 19% undecided.

The Yes camp took five points from No in a second ICM poll in January, with Yes rising to 37%, No dropping to 44% and a steadfast 19% still undecided.

The latest ICM poll shows undecided voters have dropped to just 14%, with the No camp taking all the gains and the Yes camp standing still.

Polling began four days after the Chancellor warned "if Scotland walks away from the UK, it walks away from the UK pound", and the day after European Commission president Jose Manuel Barroso said it would be "extremely difficult, if not impossible" for Scotland to join the EU.

But the poll, surveying 1,004 Scottish adults between February 17 and 21, found most Scots believe they would keep the pound and stay in Europe if Scotland becomes independent.

Some 47% said Scotland would use the pound much as it does now, against 35% who said it will not, while a substantial 57% said Scotland would get into the EU against 23% who said it would not.

Separately, the Scottish National Party published results of a poll it commissioned from Panelbase.

The main finding on the headline indy voting intention was: Yes 37%, No 47%, Undecided 16%.

Panelbase also asked about Mr Osborne's statement and voting intention, finding:

More likely to vote Yes: 26%

More likely to vote No: 19%

Unchanged: 55%.

The sample size was 1,022 people interviewed 18-21 February.
