Nicola Sturgeon is facing a triple threat to her political career as a Holyrood inquiry and opposition MSPs demanded the evidence that would corroborate Alex Salmond's claim she had repeatedly breached the ministerial code. Ahead of the First Minister's appearance on Wednesday, the committee conducting the inquiry is on Monday expected to formally request a cache of documents from Mr Salmond's solicitors that he claimed proved there was a "malicious" plot against him. It is understood a majority of the committee supports the move, which was suggested by Mr Salmond in his closing remarks of his six-hour evidence session on Friday as a means of circumventing the Scottish Government and Crown Office. MSPs hope to have the evidence cleared by the committee's legal advisors in time for Lord Advocate James Wolffe and Crown agent David Harvie giving evidence on Tuesday and Ms Sturgeon on Wednesday. The First Minister is believed to have set aside five hours in her diary. The Scottish Tories also lodged a motion of no confidence in John Swinney, the Deputy First Minister, over his refusal to hand over the SNP government's legal advice during Mr Salmond's successful judicial review. Douglas Ross, their leader, gave Mr Swinney 24 hours to release the advice or face a vote to remove him after the SNP government ignored two Holyrood demands for it to be provided. The Liberal Democrats said they would back the Tory motion and it will be considered today by Anas Sarwar, the new Scottish Labour leader. It is understood that the Greens will wait to see what is said in the motion before making a decision. Mr Salmond told the inquiry that the external counsel appointed by Ms Sturgeon's government advised that it would probably lose the case and later threatened to resign unless it was conceded. The Scottish Government has been accused of wasting £600,000 of public money by only collapsing the judicial review case at the eleventh hour, a potential breach of the ministerial code.
