Scottish pro-independence parties and groups divided yesterday over how to build on the 1.6 million Yes votes in Thursday’s referendum.

A group of SNP MSPs suggested that a “Yes Alliance” could be formed to contest the Westminster election in May, as it emerged that as many as 12,200 new members had joined the Greens, the SNP and the Scottish Socialist Party since Thursday.

But the Scottish Greens have not ruled out a Holyrood coalition with Labour, despite campaigning on different sides of last week’s divisive referendum.
