Alex Salmond has claimed there is "no obvious successor" to Nicola Sturgeon after Scotland's longest-serving First Minister announced her resignation.
The news sent shock waves through Holyrood and Westminster and saw party leaders from across the political spectrum pay tribute to the SNP leader's years of public service.
Salmond, who mentored Sturgeon during her early years in the party, warned her exit from frontline politics left Scottish independence with "no clear strategy".
