The Scottish Tories are set to back motions of no confidence in both First Minister Nicola Sturgeon and her deputy, John Swinney.
Scottish Tory leader Douglas Ross has urged other opposition parties to follow his side to “show that they have the stomach stand up to this SNP government”.
The motions followed the Scottish government’s mishandling of sexual harassment allegations made against Alex Salmond.
Meanwhile, SNP Depute Leader Keith Brown said Mr Ross is “playing political games” instead of handling the coronavirus recovery.
Brown added: “All Douglas Ross achieved with such blatantly transparent tactics was to highlight his own inexperience and lack of political nous. The Tories have always hated devolution and fought tooth and nail to stop our nation’s parliament being established.”
