SCOTLAND'S First Minister has resisted calls to suspend his predecessor Nicola Sturgeon from the SNP following her arrest on Sunday.

Ms Sturgeon has denied any wrongdoing following her arrest on Sunday in connection with Police Scotland's ongoing investigation into the party's finances.

The Dreghorn-born politician issued a statement on Twitter on Sunday evening, following her arrest and questioning by police, and her subsequent release, earlier that day.

Ms Sturgeon, who was released without charge pending further investigations, insisted she was "innocent of any wrongdoing".

Ms Sturgeon added: "To find myself in the situation I did today when I am certain I have committed no offence is both a shock and deeply distressing.

"I know that this ongoing investigation is difficult for people, and I am grateful that so many continue to show faith in me and appreciate that I would never do anything to harm either the SNP or the country."

Ms Sturgeon was taken into custody and questioned by detectives at a police station after she attended voluntarily shortly after 10am on Sunday.

She was released from custody around 5.30pm on the same day.

Police said a report would be sent to the Crown Office and Procurator Fiscal Service.

Today (Monday), her replacement as First Minister Humza Yousaf said he will not suspend Ms Sturgeon from the SNP.

He said he saw "no reason" to suspend a party member who has been released without charge.

The First Minister added: "She has been released without charge and I think it is so important that presumption of innocence is upheld."

Opposition party MSPs joined calls for Ms Sturgeon to be suspended, with Scottish Conservative leader Douglas Ross urging the SNP to "follow their own precedent".

And Scottish Labour leader Anas Sarwar said: "If you look at previous incidents in the SNP, normally people in that position have been suspended.

"And the question for Humza Yousaf is whether he is strong enough or whether he is too weak to show leadership."

Her arrest follows that of her husband and former party chief executive, Peter Murrell, and the party's ex-treasurer Colin Beattie in April.

Both were also also released without charge pending further investigations.
