SNP auditor’s resignation adds to party’s crisis amid finances investigation

Johnston Carmichael, which has produced party's accounts for more than a decade, says it reviewed its client list

The accountancy firm that audits the Scottish National party's accounts has resigned, adding to the party's crisis following the police raid on the home of its former chief executive Peter Murrell.

Murrell was arrested on Wednesday morning by police investigating the SNP's finances. He was later released without charge pending further inquiries.
