Mr Salmond’s lawyers have written to prosecutors over concerns that evidence that was given in court ran contrary to statements that were later given to MSPs on an inquiry.

Mr Salmond faced 14 offences, among them attempted rape and sexual assault. He was found not guilty on 12 charges, while another was found to be ‘not proven’. One charge of sexually assaulting a woman was abandoned by prosecutors.

Following the case, MSPs resumed the investigation into the overturned Scottish government probe.

The Crown Office has appointed lawyers to look into the allegations of perjury.

A COPFS spokesman said: “Correspondence from Mr Salmond’s solicitor has been received and will be responded to in due course.

“As is standard practice in any case regarding politicians, this will be dealt with by a procurator fiscal and independent Crown counsel without the involvement of the law officers.”
