The accounting firm used by the SNP has resigned just days after police arrested the party’s former chief executive as part of an investigation into the party’s finances.
Johnstone Carmichael had spent a decade auditing the party’s finances.
An SNP spokesperson said: “We can confirm that Johnston Carmichael will not be providing audit services to the SNP this year.
“The National Treasurer is undertaking a tendering process for alternative provision, and we have advised the Electoral Commission of that position”.
Nicola Sturgeon’s husband Mr Murrell has been released without charge pending further investigation, according to Police Scotland.
