Alex Salmond’s Alba party will propose holding a referendum on whether the powers of the Scottish Parliament should be extended to include the power to legislate for and negotiate independence.
The party’s Holyrood leader and former SNP leadership candidate Ash Regan will introduce a bill to “consult the people of Scotland” ten years on from the 2014 independence referendum.
While the SNP has won every election in Scotland since then, demands for another ballot on leaving the UK have been rejected by successive Conservative prime ministers.
The Supreme Court ruled last year that the Scottish Government cannot hold a second independence vote without Westminster’s approval.
But Alba argues that a referendum on whether Holyrood should be given more powers would be lawful.
The referendum would ask: “Should the Scottish Parliament have the power to negotiate and legislate for Scottish independence?”
