Nicola Sturgeon is adamant she is innocent of wrongdoing following her arrest on Sunday.
The former SNP leader was questioned by detectives for several hours before being released without charge, pending further investigations. No one outside of Police Scotland knows how long Operation Branchform will last. Until police bring matters to a conclusion, the investigation will hang heavy over the SNP and, by extension, the Scottish Government.
It’s for that reason Sturgeon should voluntarily suspend her party membership until the investigation is concluded. The alternative is that Humza Yousaf will face repeated questions over why he has not acted decisively against her.
