An ex-SNP MP has called on John Swinney to make way so the party can make a "fresh start" under Kate Forbes and Stephen Flynn.
Douglas Chapman, who stood down as Dunfermline and West Fife MP, has added fuel to the SNP fire which has also saw John Sillars, a former deputy First Minister, brand Nicola Sturgeon "Stalin's wee sister".
The party has tried to present itself as united since its decimation at the polls last week, despite a turbulent couple of years.
But a series of ex-MPs, including Mr Sillars and Joanna Cherry, have been openly critical about the party.
And Mr Chapman, who announced he was standing down more than a year before the election, has taken aim at the leadership as he calls for the party to "clear the decks".
He told The Herald: "I believe we really do need that fresh start, that fresh impetus, and we need to look to our members to provide that and to be brutally honest with the leadership of the party about what they think has gone wrong and what they think the solutions might be.
"We are all well aware of the shortcomings that we’ve had in recent years and that’s everything from the quality of delivery of services, the Scottish Government, and making sure that is reset and focused on, making sure we can get back to a situation where the people of Scotland actually trust us as their government."
He continued: "I know [John Swinney] has not been in the post very long, but I think it’s time to really clear the decks and use the next 700 days to make sure there is a pro-independence government in Holyrood come 2026.
"My own feeling is we need a completely fresh start and that points to a new leadership team with the attitude of putting independence at the forefront.
"The two frontrunners would be Kate Forbes and Stephen Flynn. They proved themselves over the campaign that they are articulate communicators. I think it would be a good combination with their presence both at Holyrood and Westminster."
