The Liberal Democrats will today open the door to working with the Scottish National Party to deliver more powers to Holyrood if Scotland votes no to independence.
The party suffered its worst results for a generation in last year's elections to the Scottish parliament, after the Lib Dems' coalition with the Toriews caused a collapse in trust for Nick Clegg.
In his closing speech to the Scottish Liberal Democrat conference in Inverness, Scottish leader Willie Rennie will pledge to make his party the "guarantors of change" after the referendum.

"And so now, we welcome the growing clamour for change across Britain."
Yesterday, former Liberal Democrat leader Charles Kennedy warned of the dangers of a "tribal campaign" to save the union, and called on Labour and its STUC allies to find "common cause" with the Scottish Conservatives.
Last month, Mr Cameron and Mr Darling both held out the prospect of enhanced devolution for Scotland, but only if Scotland rejects independence in a straight yes or no ballot.
