The Scottish National Party's treasurer Colin Beattie said on Wednesday he would be "stepping back" from the role until a police investigation into the party's finances was concluded.
Beattie was arrested and questioned by Police Scotland on Tuesday, before later being released without charge pending further investigation.
"This afternoon I informed the party leader that I will be stepping back from my role as SNP National Treasurer with immediate effect," Beattie said in a statement, adding that he was doing so to avoid futher distraction from the work of new party leader Humza Yousaf.
