An option to increase the Scottish Parliament's devolved powers may be included in an independence referendum, First Minister Alex Salmond has revealed.

There is a "willingness" to put a question on the ballot paper covering proposals put forward on Monday by the Calman Commission, Mr Salmond said.

And the First Minister announced his administration would publish a white paper on St Andrew's Day - November 30 - laying out a framework for an independence referendum.

He told STV News on Tuesday: "We're coming to a decision matter on these things and therefore we'll be publishing our white paper putting forward the SNP government's proposals on St Andrew's Day this year, with a view to a referendum of the people of Scotland next year and letting the people decide our own constitutional future.

Sir Kenneth Calman's commission called for Holyrood to have greater powers over income tax.

The cross-party commission - set up by Labour, the Conservatives, and the Liberal Democrats to examine the future of devolution - recommended giving the Parliament power over legislation such as drink-driving limits and airguns.

Mr Salmond, whose party declined to take part in the commission, called the Calman Report was "fundamentally weak and flawed in a number of areas".

But he said the public may be given the chance to vote for its proposals - or his preferred option of independence - in a referendum.

Mr Salmond continued: "We're putting forward a proposal for the Scottish government having the authority of the people of Scotland to negotiate an independence settlement with Westminster - so Scotland to become an independent country.

"The other parties, the unionist parties, they've come up with the Calman Commission proposals. If they're prepared to support the referendum, we can also have their option on the ballot paper so that the people of Scotland can decide whether they want the powers from the Calman, which I think are far too modest, or the powers of an independent parliament, which I support."

This would see a referendum allowing Scots to vote for independence or vote to remain part of Britain but with increased powers for Holyrood. 

Mr Salmond was asked if a third option would be provided for people who support the status quo. But he insisted: "I think folk who don't want any change will just have to vote no."
