SNP leaders today hailed a poll which showed support for independence had increased, with two fifths of Scots now in favour of ending the Union.

The survey found 41% of those questioned approved of Scotland becoming independent - only slightly less than the 43% who disapproved of such a move.

Deputy First Minister Nicola Sturgeon said the poll put support for independence and the status quo at "neck and neck"

Progressive Scottish Opinion carried out the survey, questioning 1,112 people between April 2 and 8.

The results showed a rise in support for independence compared to a survey carried out by the same firm in August last year.

Then 31% said they backed independence, while 49% were against.

This latest poll suggested support for independence was greatest amongst younger adults and lower earners, with 47% of both 25 to 34 year olds and the C2 socio-economic group giving it their support.

Those in the oldest and youngest age groups were least in favour, with 50% of those aged 65 and over against independence and 48% of those in the 18 to 24 age range also opposed.

And men are marginally more in favour of Scotland becoming independent than women, with 42% of males surveyed supporting this compared to 40% of females.

Ms Sturgeon, also the SNP depute leader, commented: "The poll shows a surge in support for independence of 10 points since last summer, and is now running neck and neck with the status quo.

"It clearly demonstrates that support for equality for Scotland is on the increase, along with the SNP's poll ratings, and is being boosted by our solid record of delivery in office - including freezing the council tax, cutting business rates, abolishing prescription charges, and restoring free education in Scotland.

"As the SNP administration delivers good government in the devolved areas, so we will build the case for Scotland to be governed equally well in all areas."

She also claimed that the "negative attitude" of the UK Government to the Scottish administration was helping increase support for independence.

There have been rows between Holyrood and Westminster over issues such as whether Scotland would keep the money it currently receives in council tax benefit if a local income tax was introduced.

But Ms Sturgeon said: "The more the London Treasury tries to lay down the law to Scotland, the greater the support there will be for independence and equality for Scotland."

She added: "The Unionist parties are running scared of the right of the people to decide Scotland's future in a democratic referendum - and no wonder, on the basis of these figures."
