Support for Scottish independence is at 39 per cent, while opposition has fallen four points to 42 per cent, according a poll published yesterday.

The ICM survey for the Scotland on Sunday newspaper revealed the highest level of support for a Yes vote since last August.

Excluding people who have not yet made up their minds, the results put Yes on 48 per cent and No on 52 per cent, leading the Yes Scotland campaign to claim it is “confident” of securing the necessary two-point swing on 18 September.
