A poll for the Scottish Daily Mail newspaper released Friday showed that support for independence has surged by 4 percent, to 47 percent ? just 6 percentage points behind the "No" campaign.

The Survation poll found 47 percent of respondents would vote "Yes" to independence, compared to 53 percent who would vote "No," excluding people who were undecided.

This is the first survey after the final TV debate between Alex Salmond, the leader of the pro-independence Scottish National Party, and Alistair Darling, the head of the anti-independence "Better Together" campaign.
