THE Scottish Greens are launching their campaign for a Yes vote in the independence referendum today.

Key figures from the party, including co-leader Patrick Harvie and MSP Alison Johnstone, will join singer Karine Polwart, above, former BBC correspondent Louise Batchelor and Green European Parliament election candidate Maggie Chapman at the event in Edinburgh this morning.

A spokesman said: "Many remain undecided and by launching our own campaign, we can reach out to those key voters."
