Former SNP MP Joanna Cherry has called on Nicola Sturgeon to apologise to those who lost seats at the General Election.
Ms Cherry added that she felt "ashamed" for the SNP "that both our reputation of governing competently and for integrity has taken a severe battering in the last couple of years".
"It was difficult to persuade people to vote SNP in this election," she added.
The vocal ex-frontbencher has been at the centre of controversy in recent years.
She was sacked from the frontbenches at Westminster due to her criticism of Ms Sturgeon, particularly over gender recognition reform.
Then-Westminster group leader, Ian Blackford, has since described Ms Cherry as "bitter", over her post-election criticism.
He said: "She is just someone who is bitter, never mind losing her seat. I have to look at everything I did when I was Westminster leader and of course I did have a good relationship with Nicola.
"Should I have pushed more on certain things? I don't know."
Mr Blackford also admitted that "there isn't really anyone else" for the First Minister's job, when asked about the party's chances under John Swinney.
