ALEX Salmond has been given until later this month to supply potentially explosive evidence to the Holyrood inquiry examining the Scottish Government’s handling of complaints against him.

The former First Minister has been asked to provide a written submission by September 23 ahead of giving evidence under oath to the panel of MSPs.

The inquiry also said it would “assess all appropriate options” after Salmond offered to take Nicola Sturgeon’s administration to court over a refusal to disclose key documents, provided the Parliament agreed to cover his costs.

The developments are contained in a letter from inquiry convener Linda Fabiani to Salmond’s lawyer, David McKie of Glasgow firm Levy & McRae.

The cross-party inquiry is looking at how the Government mishandled an investigation into misconduct claims made against Salmond in 2018.

He had the exercise set aside in a judicial review at the Court of Session, forcing ministers to admit it had been unfair, unlawful and “tainted by apparent bias”.

The collapse of the Scottish Government’s case in January 2019 left taxpayers with a £500,000 bill for Salmond’s costs, and the Holyrood inquiry is investigating what happened.

Sturgeon told Parliament at the time that the inquiry could have whatever material it wanted, but her Government has since withheld a number of papers.

Deputy FM John Swinney has said advice to ministers is protected by legal privilege, while court documents belong to the court itself, not the Government.

However, in a letter to the inquiry which was disclosed earlier this week, McKie, on behalf of Salmond, said the Government was able to release more than it had.

He said Salmond, as the “quickest and cheapest route”, was willing to supply a list of documents about the judicial review so that MSPs could ask the Government for them.

He went on: “The second option, which we are willing to undertake on behalf of the committee, would be for Mr Salmond to return to court to seek the express consent of the court to have those documents passed to the committee.

“Whilst we are more than content to make that application on behalf of the committee, we would require clarification that all legal costs would be met by the committee.”

In a reply issued yesterday, Fabiani said: “The committee will continue to assess all appropriate options in seeking the documents and information necessary for its scrutiny and will come back to you at a later stage to update you on its progress in this regard..

“The Committee appreciates the complexities involved in all of this and your client’s desire to see the full statements and evidence from the Scottish Government. However, the Committee is also mindful of the need to progress its inquiry.

“To that end, we would ask your client to make a written submission, to the extent to which he is able, by September 23.”

The former First Minister was cleared in March of sexually assaulting nine women following a three week trial and after his acquittal he made a statement outside the High Court in Edinburgh saying there was “certain evidence” he would have liked to have led but for a variety of reasons was unable to do so.

He added that it would see the light of day later, suggesting once the coronavirus pandemic had subsided.

The allegation of a political conspiracy against Salmond formed a key plank of his defence at the former First Minister’s trial.

Over the summer Sturgeon dismissed claims of a conspiracy against her predecessor as a “heap of nonsense”, saying she would “elaborate” in the future.
