A debate on the motion of no confidence is now scheduled for Tuesday, rather than Wednesday as had been expected, although it is subject to final approval by the Parliament’s business bureau on Tuesday morning.

The motion has been tabled by the Scottish Conservatives after the party’s leader at Holyrood, Ruth Davidson, claimed there was “no question” the First Minister had lied to Parliament.

The Tories had threatened the motion of no confidence prior to Ms Sturgeon’s appearance before the Committee on the Scottish Government Handling of Harassment Complaints, set up after a successful judicial review by Mr Salmond resulted in the Scottish Government’s investigation being ruled unlawful and “tainted by apparent bias” in 2019.

But following a leak the inquiry has reportedly concluded that Ms Sturgeon gave an “inaccurate” account of meetings with Mr Salmond, the party repeated their calls for her resignation.

Another inquiry, carried out by the independent adviser to the government on the ministerial code, James Hamilton, has concluded and will be published on Monday.

According to Sky News, the leaked report by the Holyrood committee also finds it “hard to believe” Ms Sturgeon’s testimony of when she first heard about concerns relating to the former first minister’s alleged behaviour.

The SNP leader’s spokesman said she stands by her evidence and accused the committee of resorting to “baseless assertion, supposition and smear”.

In her evidence to the committee, Ms Sturgeon said she first became aware of any potential inappropriate conduct by her predecessor after a media inquiry in November 2017 about an alleged incident in 2013 involving female Edinburgh Airport staff.

MSPs on the committee reportedly believe Ms Sturgeon knew of concerns about Mr Salmond’s conduct before this and should have acted.

Further leaks suggest the committee’s report, due to be published on Tuesday, states a majority of members are “concerned” it took Ms Sturgeon two months to tell the head of Scotland’s civil service she knew about the investigation.

Ms Davidson said: “If Nicola Sturgeon has a shred of integrity, she should be considering her position. She has every opportunity to do the right thing and resign.

“No First Minister is above the fundamental principles of honesty and trust.

“There is no question that Nicola Sturgeon has misled Parliament and broken the promises she made to tell the truth.”

Asked about the leak on Thursday evening, Ms Sturgeon told Sky News: “I stand by all of the evidence I gave to the committee, all eight hours’ worth of evidence.

“What’s been clear is that opposition members of this committee made their minds up about me before I uttered a single word of evidence, their public comments have made that clear.”

A spokesman for the First Minister said some opposition members “appear intent on breaking every rule in the book in a blatantly transparent attempt to damage her before the coming election”.

He added: “The latest leak from the committee, suggesting they find it hard to believe that the First Minister did not previously know about inappropriate behaviour on the part of Alex Salmond, is not supported by a single shred of evidence.”
