Ms Sturgeon was questioned by police investigating the SNP’s finances and was released without charge on June 11 pending further investigation.

Returning to her Glasgow home this Sunday, she said: “I can’t say very much just now, what I will say is reiterate the statement I issued last Sunday, I’m certain that I have done nothing wrong.

“I intend to be back in Parliament in the early part of the week, I’ll make myself available for questions then.

“For now I intend to go home and catch up with some family.”

Asked whether she had considered stepping back from the SNP, she said: “I’ve done nothing wrong and that is the only thing I’m going to assert today.”

Ms Sturgeon added: “I know I’m a public figure, I accept what comes with that, but I’m also a human being that’s entitled to a bit of privacy and my neighbours are also entitled to a bit of that as well.”

Asked whether conditions have been placed on her arrest, she said: “No and I’m not going to get into anything other than that.”

Police Scotland confirmed last weekend that a 52-year-old woman had been arrested in connection with the ongoing investigation.

Ms Sturgeon quit as a minister and SNP leader in early April, shortly before the arrest of her husband, Peter Murrell.

Mr Murrell, the 58-year-old former chief executive of the SNP, was detained on April 5 at the couple’s home in Uddingston, close to Glasgow.

He was interviewed under caution following his arrest, before being released without charge.
