Scottish independence: Scottish Green Party launches 'Yes' campaign
The Scottish Green Party has launched its campaign for a "Yes" vote in next year's independence referendum.
Key figures from the party set out why they believe Scotland would have a better future outside of the UK.
Co-convener Patrick Harvie and fellow Scottish Green MSP Alison Johnstone joined singer Karine Polwart at the event in Edinburgh.
They said it was "increasingly hard to imagine" a Westminster government which embodies Scotland's values.
The party said Scotland's political culture was "ready for the challenges ahead" and described the forthcoming Scottish government's white paper on independence as the "starting point" for the transition to new powers.
The Greens said a new constitutional convention should be created by the end of 2014 if there was a vote in favour of independence.Undecided voters
And the party said it believed that Scotland could only establish full economic independence if it was ready to develop its own currency.
Patrick Harvie, the co-convener of the Scottish Greens, said: "The debate which Scotland has embarked upon is about far more than whether decisions should be made at Westminster or Holyrood.
"We have the opportunity to ask ourselves what kind of country we want to live in, what kind of society we want to build, and what kind of economy we want to run.
"Scotland has the opportunity to take control of its future and build a political culture that's capable of change. Scottish Greens will reach out to undecided voters and make the case for choosing a better future."
Voters in Scotland will be asked the straight yes/no question: "Should Scotland be an independent country?" when the referendum is held on 18 September 2014.
