The SNP is under pressure to suspend Nicola Sturgeon following her arrest on Sunday as part of a police probe into the party’s finances.
The former first minister has said she is “innocent of any wrongdoing” after she was released without charge pending further investigation.
The former SNP leader said she has found the situation both “a shock and deeply distressing” and thanked people for sending messages of support.
Scotland’s first minister, Humza Yousaf, has been urged to suspend Sturgeon by SNP MPs and Scottish Conservatives.
Scottish Conservatives chairman Craig Hoy said: “Nicola Sturgeon and other senior SNP figures - including Humza Yousaf - must co-operate fully with this police investigation and commit to full transparency surrounding it.
“The SNP continue to be engulfed in murkiness and chaos. Humza Yousaf must now show some leadership and suspend his predecessor from the SNP.”
Ms Sturgeon’s arrest comes after her husband Peter Murrell was arrested in April.
Mr Murrell and MSP Colin Beattie, who was SNP treasurer at the time, were both released without charge pending further inquiry.
