The Scottish Greens are launching their campaign for a Yes vote in the independence referendum.
Key figures from the party will set out why they believe Scotland would have a better future outside of the UK.
Co-leader Patrick Harvie and fellow Green MSP Alison Johnstone will join singer songwriter Karine Polwart, former BBC correspondent Louise Batchelor and Green European Parliament election candidate Maggie Chapman at the event in Edinburgh this morning (Friday).
The Greens will likely set out why they believe it is increasingly unlikely that a Westminster government will address Scotland's needs.
They are expected to outline the track record of devolution under which politicians have kept the NHS in public hands and maintained free education.
Greens will give their views on the Scottish Government's forthcoming White Paper on independence, the transition of power in the event of a Yes vote and how this power could be used to create a better Scotland, as well as the time-scale for writing a constitution for an independent country.
A party spokesman said: "The independence debate is a chance to ask what kind of society we want, what kind of economy we want. Many voters remain undecided and by launching our own campaign, Scottish Greens can reach out to those key voters.
"We look forward to making the case that a better Scotland is possible, and that a Yes vote is the best way of getting there."
